Golden Trick, Applying Different Symbols to Different Elements Automatically

Have you ever tried to apply different tags to targeted elements by elements property, for example, a door with different Fire Rating, has to get a different symbol, how you would do it?

Yes, it could be tedious and time-consuming if you go and do it manually.

Well, you want to do it by Dynamo or developing your own plugins!??!

Wait a moment, watch this video and then try again to handle the case.

Hope you like it,

Demolition Phase and infill wall


One of the common issues that many Revit users are talking about it the demolition phase in Revit and the way Revit will try to fill the Door or Window opening in walls, once you chose a demolished phase for your element.

By searching about this matter you will find some workaround with pros and cons and I believe that the solution I’m suggesting here is the fastest way that we can address this not just graphically but also with regards to schedule and QS.

You can find the solution in the video,


Hope you like it and let me know what is your opinion,


Addressing issue for Level and Grid Bubble size in different view scale?!


Let’s address another issue that we can face within our projects,

As you already faced with this issue, when you are changing your view scale from 1:100 to other scales like 1:200 or 1:50, your grids and level symbols will not be presented with the proper size,

We can find some solutions in different blogs or websites, like design options or using separate link files for different scale, which can make some other problems and make our management process more complicated.

Let see how we can address it through below video,

Control Room Separation Lines across different Disciplines

Hi again,

Tonight i want to share another tricks which i shared in BiLT ANZ 2018,

Let’s solve one of the big issue and answer to this question, How we can control Room separation lines in Link file, when we are sharing model across different disciplines?

This is one of the biggest request from M&E people, when they are creating space in M&E file they need to define their spaces with freedom and without any restriction from Archi layout.

You can see one example in below.  in left side we have Room separation lines, which you can see with red color.


Regarding to Archi discipline for this building we have separate area for manager, reception, counter and lobby. And the way they are defining this separation is according to furniture placement, different material or partition system.

But maybe for M&E, all of this area are part of one space and no need to define separate space for each portion.

Now if we go for M&E file and make try to define Space in according to Archi Layout, this will not be possible.


Go to Archi Model and make try to define new Phase, you can call that “Room Separation Line”


Select all Room Separation line from model and after that for demolition phase, define Room Separation Line.

Yes just this, make save your file and go to M&E file, make delete all Space that you have for Manager, lobby, etc.  You should do it with Space schedule and select those space that you want to delete and make them delete from schedule.


Now if you retry it again still you can see same effect and you cannot make one space for all area.

Select your archi model link and go to Edit Type from properties panel. In Edit Type dialogue box go for Phase Mapping and change phase mapping system like below picture.

Everything is set up now and you can define new Space without any limitation from archi room separation line.


I hope you enjoy and this could help you for managing your project,

I received comment, trick was very simple, perhaps it is. 🙂

Revit is much simple than we think and in most of the time we can solve issues without Dynamo and scripting,

Take care,


How we can define 2D Tags/Symbols with Rotate option?!?

Hi to all,

Now after while i just want to share one tricks with you, which i shared in BILTANZ 2018,

This is very useful tricks and i’m sure when you are delivering projects, you will face with this issue or you already face with it.

Just take a look to below picture, did you saw this before? one Tag with two label text, for example : Type Name, Column Location.



But, but because you need to present this label text with different direction you have to make duplicate from that and you have to define extra parameter for visibility to say for 45 degree which item should be presented, or for vertical and Horizontal.

let’s finish this story one time at all.

Just define one new Generic Annotation, you can say this should be Furniture Tag or any other Tag.




Define Label Text as you need and define right location regarding to reference point of two reference plane.

Go for another Generic Annotation Family, you can call that “For Angle Definition”. Define one annotation line like below picture,

Now just load it into your Furniture Tag Family and define location for placement like below picture.

Select Generic Annotation Family “For Angle Definition” and label text object and put them in the group.


Define one Reference Line with 45 degree like below picture and make it Pin.

Now you need to define one Angular Dimension between Reference Line and that annotation line from “For Angle Definition” family.

Call that “Overall Angle” and define another parameter “Angle”. In formula row for Overall Angle define this ” Angle+135 “.

Select angular dimension and make it change to Overall Angle.

As you can see in below picture, suddenly you will get sort of result like reverse for you text element.


Go for edit group and make edit your group according to below pictures and step that you can see.


Make click and drag on the grip that you can see and do this clock wise .


You will get result like below picture and say Finish Edit mode for group.


Move you group from reference location like below pictures to the center of family, which is intersection of two reference plane.


Like below.


Now go to family “For Angle Definition”  select annotation line and say turn off visibility. Load it into your Tag family.


Orwrite Existing Family .

Now you can define new family type regarding to any angle as you want. Like H,V,30,45,60 or any other.



Next trick will be next week.




My promise, For Golden Tricks in BiLT ANZ 2018!?

In this year, 2018, my proposals become accepted for four BiLT Event around the globe. I am very excited and i know it’s not possible to find better opportunity for sharing knowledge in four different continent.

We just finished BiLT Asia 2018, three weeks ago and next one will be BiLT ANZ.

In passed one year i wasn’t active in my blog and i didn’t shared with you about new tricks which i can say no body knows in the world,

Now i have chance to share “Golden Tricks for saving your life!?!?” with you in this event and I truly believe BiLT ANZ 2018, is the right event for sharing all new tricks with you,

Some of major Tricks are as below:

  1. If you want to know about making active or deactivate your Room/Space separation line across discipline!?!
  2. If you want to know about 2D Tags and Symbols with Rotate Parameter!?!
  3. If you want to know how you can do your project lighter ten times than normal way!?!
  4. If you want to make your BIM Model optimized with simple process!?!
  5. If you want to compare four number with each other and find bigger/smaller one with one formula in one line!?!?
  6. If you want to define Structural column but with calculation in your GFA!?!
  7. If you want to know about fast and simple way for FFL and SFL in your project!?!
  8. If you want to make optimize your BIM Model for CFD Simulation, with simple workflow!?!

And many other “IF”, you can attend for this session and you will never find this type of tricks anywhere else.

At the end of this session you will left the room with big smile, you know why!?! just because all of those tricks are very simple.

ReInvent Revit Users!

Since around 15 or 16 years, i starts my journey with Inventor and i was joying to work with this software. One of the best software for manufacturing and construction stage in the market.

Also,  when first time i starts to work with Revit, i found lot’s of familiar tools and icons. Which is common in Autodesk platform. Step by step after i start with Revit journey, i understood in many parts logic and the way we are defining parameters, doing modeling, assembling elements, defining rules, providing drawings is same with Revit.

In market, every time and every where i meet different Architects or Engineers, who were very interested to learn one software for construction stage or for providing construction details for different products or complex shape that they designed.

But every time sort of concern or doubt about manufacturing software make them disappointed to learn anything about this category.

In next April, i will deliver one talk in BiLT Asia 2018 “ReInvent Revit Users” and i will show to all, how with 2 hour you can become Inventor User.

If you are currently Revit Users and you want to become Inventor Users in 120 minutes this session is for you.

You can receive more information from below link:

See you all, in #BiLTASIA 2018


How we can create Hatch Pattern with Notepad?

I know this is not unique post but i’m sure this could be one of the useful post for all Revit or AutoCAD users,

I think that was around 12 years ago, i bought one book and i read one interesting thing about how we can understand what is happening in AutoCAD.pat file and how we can make decode that.

For that year, regarding to my experience and knowledge and also regarding to the explanation of that book , that was very hard for me to understand what is happening in *.pat file, but that was first start.

With many try i understood more about *.pat file, but every time i didn’t try for create more than 1 or 2 years i forgot something.

Now i want to make it documentary and share this with you my friend, then every time i forgot something i can make review this post for myself.

Let’s start this.

As you maybe know we can try to create *.pat file with notepad in our computer and after we wrote our codes we can save our files with .pat extension.

I want to explain this with three different type of Hatch with three separate post in my blog, all dimensions are mm. 

  1. Tile 300×300 Grout 10


2. Tile 300×300 Grout 10 Round Corner


3. Brick 300×80 Grout 10


Ok, let’s talk about first item ( Tile 300×300 Grout 10 )

At first i should tell you one important point, if you need to define any new hatch, my offer is try to draw that hatch with line in AutoCAD regarding to simple X,Y axis like to the below picture.

Honestly, this is very important for you if this is first time you are making *.pat file and if you are making complex hatch pattern.

Because you can understand what is happening in pattern, for example for each pattern you need to have information about separate item like below list:

  1. what is the base shapes for pattern? 
  2. How many line you need to create that base shapes shape?
  3. What is the Angle for Lines? ( We call that Angle )
  4. What is the start Point coordinates for each Line regarding to 0,0? ( We call that A for X and B for Y )
  5. What is side offset for each lines? ( We call that C )
  6. what is the exact side distance between line pattern? ( We call that D )
  7. what is the length of that lines? ( We call that E )
  8. what is the Gap between lines? ( We call that F )

In next steps i will answer to above question one by one. But before we start that i want to show you final result ( *.pat file ) for this simple hatch. take a look to below pictures. as you can see



1. what is the base shapes for pattern?

Take a look to below picture, as you can see we have one simple square ( Main Tile ) and we should make pattern from this shape along to X and Y axis.

As you can see in below picture Tile (Square) size is 300mm and Distance between Tile is 10mm.


2. How many line you need to create that base shapes shape?

As we said we have Tile with 300mmx300mm and for create any square we need four line. Take a look to the below picture, you can see four line and as you can see, this lines have sort of pattern .



3. What is the Angle for Lines?

Line 1 and 3 are parallel with X axis, that means is the angle value for this line is 0.

Line 2 and 4 are parallel with X axis, that means is the angle value for this line is 90.


4. What is the start Point coordinates for each Line regarding to 0,0?



line 1


Line 2


Line 3



Line 4



5. What is side offset for each lines?

Ok, take a look to the below picture, as you can see we have line 1 along to X direction and we said, angle for this line is 0. But if you pay attention we should have have parallel pattern from Line 1 for Tiles, that are duplicating along Y Direction. Number of this pattern is unlimited.


Now take a look to below picture, as you can see if you need to move Parallel pattern of Line 1 along to X direction you can add value for ( C ).  This number is side offset for Line 1.


6. what is the exact side distance between line pattern? ( We call that D )

Take a look to below picture, as you can see we have distance between Parallel pattern of Line 1.  you can see same thing for other lines.

Line 2

Line 3


Line 4

7. what is the length of that lines? ( We call that E )

Take a look to below picture, as you can see, length for all lines is equal with 300.

8. what is the Gap between lines? ( We call that F )

Final item is Gap between co-linear lines. Take a look to below picture, you can see we have Gap between Line 1 Co-Linear pattern and that one is equal to 10.

The only point is, we should use minus number. then -10.



Now we have final result as new pattern for our usage in Revit.

Good Luck.

Top Ten Speaker in BiLT Asia 2017

That was my first experience of BiLT Asia 2017,

I become one of the Top Ten Speakers in this event ( Rank 8 ) and i should say tank you to all Speakers for what you are doing for sharing your idea and making this event more valuable year by year.

Also I should say thank you to BiLT Committee for what they did for preparing this great event and gave me this chance to be Speaker for this.

I was very lucky because i meet many great and knowledgeable people.

I should say Thank you to Wesley Benn, Phil Lazarus, Richard Kuppusamy, Chris Needham, Phil Read,  Heidi Lam.

And also i should say thank you DP Architect and my two friends Hui Min Chan and Kelvin Tam for Supporting me.

And i hope to be speaker in next BiLT Events.

What i Learnt from AU Proposal Submission?!?!?!

At first i should say congratulation to all Speakers for this year.

I was thinking about the Title for this Post and many things comes up in my mind, but at the end i should say this is the best Title : What i Learnt from AU Proposal Submission?!?!?!

Let say why :

In past three years i sent many proposal and i learnt many thing that i can share with you year by year. For each year i will tell you about two condition, Before, and After proposal rejection.

In 2015 :

Before Rejection : I sent some proposals, and i was thinking everything is ok for me to be a Speaker for this event, in this year we had to make upload video from our desktop to describe about what we are going to explain in AU.

After Rejection : Honestly when i was recording that video’s I understood my language isn’t good enough for talk in AU ( Still it’s not prefect but in 2015 that was sort of night mare and also AU it’s not about English Course if i be correct it’s about unique idea and experience and workflow …  ) , then i start to read more English paper and listen more, but because always i was busy, i hadn’t any time for study English. Also, i said maybe AEC judge need more prove regarding to my words and skills, because of this and my interest for ACP ( Autodesk Certificate Professional ),  i went to Dubai and i passed Six ACP Exams in Revit ARC, STR, MEP, AutoCAD, Inventor, 3ds MAX.

Also for my interest and after many years work with Dassault System software i went to India for 10 Exams in three day. And i passed all professional Solidworks and Catia Specialist levels.

In June of 2016 i was Speaker in AU ASEAN for one Title, Excellent Detailing in Wall, Floor, Roof, Ceiling. That was one of the best experience for me, that i will never forgot it, not because of the Event, because i meet many nice people, Like Phil Lazarus and  Takrit Jirawudomchai, Gianluca Nicholas Lange.


In August of 2016 i understood two items of my Proposals in BiLT Asia Event was accepted.


In 2016 :

Before Rejection : OK, my perception was this, now i have many prove for my skills and knowledge, i just tried to find title from what i did in passed year. I had more experience in English language. I was Speaker in AU ASEAN too.

After Rejection : I understood this is not about the Unique Idea, Experience or Knowledge, because of many reason. ( In more than three items my proposal was hundred percent Unique that was coming from real experience )

But i make decision for sharing my Idea with others with this Blog. This was really nice experience, because i found many friends around the globe through to this blog and Linkedin.

Also i wrote two Paper for AUGI. About unique Idea in Revit for 3d Detailing and Historical Building with Inventor.

Also i changed my location from Iran to Singapore, i was looking for new Environment with cloth relation with community and people and for passing sanctions.

I was thinking i should have experience with International Company, Because they have different experience that could be more valuable from Iranian construction market.


In 2017 :

Before Rejection : I think for this year i was ready enough, anything for proving my words and experience. I had BiLT Experience with great feedback and also BIM Manager in DP Architect. Regarding to AU Blogs in this year we had this opportunity to add weight to our Proposal with Vote ( Toooo much Weight ) . I received more than 80 vote for my Revit Proposal; Golden tricks in Revit. And more than 70 Vote for Re Invent Revit: Inventor for Revit Users.

Honestly around 8 of votes that was coming from my laptop and mobile phone and four of my friends.

After Rejection : Currently i’m shocking,  i’m thinking i am really stupid for sending Proposal in AU Vegas. Maybe in next one or two weeks i will forgot this sense.

But, let’s see what is Autodesk Respond to me in each Year after i sent more than 10 proposal in three year.




You can see what i received every time for rejecting my proposals.

Also you can see my blog views jus in four weeks i sent some post regarding to my proposals:


How i should add weight?!?

But i have one question from those people who are judging about the proposals:

Do you believe to below words ???

( AU selection is based on the strength of an individual proposal, a speaker’s past conference experience or industry expertise, and the collected feedback of Autodesk employees and AU community members. It’s the combination of these factors that shapes AU’s selection process.. )

I can’t say anything ……………


Big secret in AU Session ; How we can create Tag with Rotate Parameter?

Every time i’m talking about tricks i’m receiving many feedback and in many case my friends around the globe, they are saying we are following precise workflow for doing this and we never though that could be easy as this way.

Always, at that momement i am very happy, because i think i’m teaching and also learning from their workflow.

One of the big tricks i want to explain in my AU Session for this year is about Tag with Rotate Parameter . That mean is you don’t need to have separate family for horizontal or 45 degree and also you don’t need to have one family with many Label Text in different angle.

Take a look to below pictures,


yes, it’s possible and this is the way we can push the limits.

I will share with you about this tricks in the future but for now i need your help.

Currently i sent proposal for AU University 2017 and i need your vote. If this type of tricks are interesting for you please go to the below website and make search for this two title:

  1. Revit : Golden Tricks for save your life!
  2. Re Invent Revit: Inventor for Revit Users!




Good Luck.

Big secret in AU Session ; How we can make active/deactivate Room separation line in Revit!!!???

It’s become around 7 years ago when for first time i start to make link from Archi model into Revit MEP and i found some road blocks , many of those difficulties was solved after i did many projects and many of them was remained.

Now i want to show you how you can make turn on/off Room separation line from Archi Link model in MEP discipline and important things is when you are making turn off you can create your space without any limits that is coming from Archi Separation line.

As you can see in below picture we have simple plan with Room Separation line in Archi model.


In below picture you can see after i make insert Archi model in MEP project, still i can see Room Separation lines and if i try for create any room or space i will receive affect from room separation lines.


And now i make turned off all room separation line from Archi Link and then i make new space according to Space separation line in MEP.



I will share with you about this tricks in the future but for now i need your help.

Currently i sent proposal for AU University 2017 and i need your vote. If this type of tricks are interesting for you please go to the below website and make search for this two title:

  1. Revit : Golden Tricks for save your life!
  2. Re Invent Revit: Inventor for Revit Users!





Good Luck


Re Invent Revit: Session 4, 2D Sketch assignment

I think without assignment we will not achieve to anything, hence I thought maybe i should prepare some record from 2d Sketch environment. In some part of this records I will show you how we can do something in Revit and how we should do that in Inventor.
You can watch records in below, also i should say in next few days i will make more record about 2d Sketch.



After you tried for this, if you need any help just ask I will tell you how you can make fix problems.
Good luck.

AU Proposal for 2017 : “Revit : Golden Tricks for save your life!”

Dear All,

This is my second proposal for AU Vegas 2018. Again i want share with you my knowledge. I don’t know how much you had suffer for managing Room Separation line in M&E side but, One of the hottest trick for this session is about how you can make turn Off/On for Room Separation line in M&E side. Yes in Revit. Also about Room and design option and many other tricks for you.

Take a look to the description from below link, you can make search with “Golden Tricks” (I know my English it’s not prefect) and do vote for idea if you think i deserve for this.

you can find more info about me from below links:

Re Invent Revit: Session 3, 2D Sketch

Now you know about many thing in Inventor, we can go for first modeling feature.

Like Revit or any other software, when you want to make extrude at first you need to have one 2d Sketch and after that you can go for Extrude command.

As you can see we have separate icon for create 2D Sketch.

But we have two major difference here:


  1. In Revit you don’t have separate command for create 2d Sketch and each time you are hitting Extrude command you will go to the Sketch environment and you can have access to 2d Tools like line, circle, rectangle and etc. But in Inventor you should have 2D Sketch at first and then you can go for Extrude. Take a look to the above pictures.

2. Another thing is about the Work Plane , in Revit if you are in Reference Level, Current Work Plane is Reference Level and if you are in Front/Back or Left/Right view you can use Set Work Plane command to make set one Reference Plane for 2D Sketch, but in Inventor after or before you run 2D Sketch tool you should select one Origin or User Work Plane or like in Revit You can select One Flat Surface for create new 2D Sketch.

In Inventor you have many tools for create 2d Sketch and honestly in some case you can’t find any equivalent tools in Revit but still you can find many similar tools and workflow, I can give you short brief about this tools in Inventor and you can read about that in below.

Note : In Revit we hadn’t any 2D Constrain until to Revit 2017, in this version you can see only new item and that one is about Tangent Constrain for Arc shape and you can see relevant picture in below:


Note : In Revit you can’t use Array Command for make Array from elements that we have in 2D Sketch.

Option Bar:  Before of short brief i should explain about Option Bar in Revit and equivalent item in Inventor, as you know after we run any tool in Revit we can find some option according to that tool in Option Bar i want to explain about this with two simple example :



1. Revit : Copy = Inventor : Copy  : As you can see in Revit you can run Copy command at first and after make select your objects, press Enter and then you will receive some option in Option Bar , but in Inventor after you run Copy command you can receive dialogue box regarding to the Copy and all option are appearing in dialogue box.



2. Revit : Offset = Inventor : Offset   ; As you can see for Offset Command After we run this tools in Revit we can see different option in Option Bar but in Inventor after we run Offset command we are not receiving any dialogue and with Right Click we can see some option like Loop Select or Constraint Offset and also if you make click at any objects you can define value for offset tool.

Note : In 2d Sketch environment we have 2d constrain which could be little strange for anyone who hasn’t any experience with this. But if you are that type of user in AutoCAD who is using Constraint then you can find many similarly way for apply 2d constrain.

In Inventor you can see after you run move command you will see Move dialogue box and then you can select your objects with selection button and define two point with location.

Note : All tools for draw are very similar to Revit.

Note : All tools for Modify are very similar to Revit

2d Rectangular pattern in Inventor : In Revit you can make duplicate 3d elements with Array Linear, the biggest problem is you can define one axis for this but here in Inventor you can define two axis for make array from 2d elements and actually this tools is very similar like AutoCAD Rectangular Array.

2d Circular pattern in Inventor : In Inventor we can make pattern from 2D Elements with Circular Pattern and the only thing you need to define here is about the object for duplicate and Center of array, also this tool is like AutoCAD.


Inventor Mirror : Take a look to above picture

Note : In Industrial Software like Inventor we have different color for 2d Sketch elements and also if we have any sketch with all dimension that we need to make control for size and location of sketch, we can call that Fully Constrain. I will show you one simple example in below pictures and in the future we will learn more about this:


You can see one Rectangle with all dimension as full constrain and another Rectangle without dimension as a free shape. pay attention to the color.

As we said we will discuss about this in the future.

Good luck.

Re Invent Revit : Session 2

Ok, Second Session is about modelling procedure, after short explanation in “Session 1″for file type in Inventor and compare that items with Revit now it’s the right time for start new model in Inventor.

But before we start to talk about this item, i should tell you one things about what we are doing usually in Revit and what we should do in Inventor.

Every time i’m teaching Revit, i’m explaining about Project Environment at first then after that i’m going for Family.

The point is in Revit because of two thing:

  1. Template for create new projects. (In every project template, we have different type of Wall, Floor, Roof, Ceiling, Stairs, Railing, as system families and also we have different type of Loadable family like Furniture, Columns, Beam, Door, Windows)
  2. Default Content Library. (We can find many different type of Furniture and Column, Door, Window, Tag, … etc that are very useful for start new project)

we can start from project.

Just for one moment imagine this in Revit, you starting new project, but you don’t have any family?!? I’m talking about all family like Systemperature Family, Loadable Family or Model-In Place Family.
Now what you should do?!?! Yes, you should create all things by your own.




Note: If we try to make compare as this way it’s not fair , because I can say in Inventor we have biggest default content in the world for industrial usage. Pay attention, Industrial. It’s not Door or Window it’s Screw, Nuts, Washers, Pin, Ball bearing, Roll Bearing, O Rings and etc. If i remember correctly more than 650,000 parts.


Hence, we have all basic requirements for create new Building ( Project ) in Revit because of what we have as a predefined Project Template and Default Family Content (Library).

I think now you know why we are going for Family in Inventor at first, let’s go for Part Modelling with IPT file and at same time we will try to make compare between this item and “Metric Generic Family” in Revit. Just follow below step for create first part (Family) in Inventor.

Or you can go for new part according to below picture :

Note : If you have need to make change for default Template according to different Unit like Imperial to Metric or vise versa, you can go for setting like above picture and change the Unit and Standard as you can see in below.


Now you should have result like below picture, yes we are in Part ( Family ) environment.

At the same time you can go for create new family in Revit, as i said before that Family could be “Metric Generic Family” which is None Host Family.

As you can see in above picture we have many similar item in User Interface. Ribbon, Graphic Window, Project Browser/ Properties Panel=Design Tree.

Note: In Inventor if you need to go to the Isometric view ( 3D View in Revit ) just press F6 from your keyboard and if you need to make orbit, you can go for Shift+Click and drag with Scroll like in Revit. Also if you need to make zoom in or zoom out go for F3+Click and Drag with Left mouse button. You can use F5 for go to the previous view.

Now, i have one question, did you ever think why when you are working in Project Environment you have North, South, East and West view but when you are making model for Family, you have Front/Back and Left/Right view?

Answer is, Because you are making Product, yes Product and Inventor is very powerful for this part.

Ok, lets see what we have as Work Plane in Inventor?!!? Maybe you want to say what is the Work Plane? Work Plane is same like Reference Plane in Revit.

Like Revit in Inventor you have Default Reference Plane ( In Inventor you can call that Origin Work plane ) that is coming from the Family (Part) Template, Like Front/Back , Left/Right and Reference Level in Revit we have XZ, YZ and XY Work Plane in Inventor.  You can see how we can make compare between this item in below picture.


Ok, until now you know about Reference Plane, but one thing is remained here and that one is Family Type Dialogue in Revit !?! do we have anything like this in Inventor. Haha , yes, we have. Take a look to below pictures:



Please don’t forgot about this, Inventor is Mechanical Software and because of this we have more ability than Revit, in the future session we will discuss about many things for creating Parameter in Inventor but for now i can tell you one simple thing and that is about the name of parameter.

If you have parameter in Revit Like ” Frame Length” in Inventor you should type that as this way “Frame_Length” that mean is you can’t use space between words in Inventor and you can use “_” .


Good Luck

Re Invent Revit : Session 1

First Session is about how we can start to work with Inventor. Remember, my mindset is, currently you are working with Revit, then you know about 3d Modelling and you know about Project and Family well.

but be aware about this in Inventor we have different way for modelling and different solution for do anything, hence when i’m explaining anything that item could be about usual items and maybe we could find many different way for do same things, another things is, every time i;m trying to find any method or item to make compare with Revit and say about same solution with Inventor

OK, every time i had any class for anybody or any groups they have one similar question, when we opened Inventor software at the first time we saw one dialogue box and we was confused what we should do and which item is correct for our work.

Take a look to below Picture, yes this is what they saw in first try with Inventor.


Let me explain about first dialogue according to Revit perception.

Description : As you know every time you want to make any project in Revit you need to put some family together, Like Wall, Floor, Roof, Ceiling (System Families) Window, Door, Furniture, Mechanical Equipment, Case work (Loadable Family=User Family ) Mass , Generic Modelling in Project (Model in-Place ) . Hence any project is combination of Family.

Here in Inventor Part is equal to Family and Assemble is equal to Project.

Simple clarification :

1. Revit : You can make a Project in Revit and bring other projects as a link into that = Inventor : In Inventor is same you can make an Assembly and bring other assembly as a Subassembly the only different is in Inventor you can make edit in any subassembly as you want but in Revit you cant make edit in Link object.

2. Revit : You can Make a Family in Revit and load it into other family as a nested family ( With this Method you are trying to make Sort of assembly in Revit )= Inventor : Usually in Inventor when you want to make assembly you can put Part object in Assembly file, (( I should say still you can make a Part and load that Part in new Part as a Drive Part) ( Also you can load Assembly in Part ))

3. Revit : In Revit you need to do modelling for Projects, in Project Environment = Inventor : In Inventor you need to make your Parts and put them together to make your Assembly ( Project ) .

Note: Actually you can do modelling in Assembly Environment with two different way and you can read about that in below .

5. Revit : In Revit Project Environment you can create Model in-Place Family and you have all feature according to Family Modelling in Project Environment = Inventor : In Inventor is same, you can use Assembly Feature and make join or cut with Part solid models, but you can not save this Feature as a new *.ipt Part and they are part of Assembly environment

6. Revit : In Revit Project Environment you can create Model in-Place Family and you have all feature according to Family Modelling in Project Environment = Inventor : In Assembly Environment you can create new Part and make active your Part Feature and create parts inside of Assembly , Difference is in Inventor you can save that part as separate Family but in Revit normally you can not do this.

Revit Family = Inventor Part

File Extension for Revit *.rfa = File Extension for Inventor Part *.ipt

Revit Project = Inventor Assembly

File Extension for Revit *.rvt = File Extension for Inventor *.iam

Simple clarification :

Q 1 ; What is the Sheet Metal.ipt ?

A 1 ; As you can see Sheet Metal.ipt is sort of Part in inventor but you can find different feature for modeling, all feature are relevant to Sheet Metal Objects, Like Water Tank, Metal Cabinet, Metal Desk, Metal Door, Cladding,

Q2 ; What is the Weldment.iam ?

A2 ; IN any case that you need to do Welding projects you can use Weldment.iam.

Q3 ; What is Standard.idw ?

A3 ; With Standard.idw file you can create drawing from any *.ipt or *.iam file , important point is in Revit you have Sheet Subset in Project Browser and Annotate Ribbon for Dimension and Symbol. But in Inventor you have separate file type (*.idw) and environment for prepare drawing.



Q4 ; What is Standard.ipn ?

A4 ; Naturally Inventor is a software for Mechanical Engineers and Product Designers, in many case this people needs to make a presentation from their Assembly, that how we should make assemble or disassemble any mechanism .  If we want to make example like this in Revit we should talk about Displacement tool. you can see similar result in Revit and Inventor in below picture.



We will discuss about modelling workflow and we will compare Revit solution with Inventor solution in the future.

Good luck.

Re Invent Revit : 1.Introduction


I was speaker for BiLT Asia event and I had two session, one for Revit and another for Inventor.


Assembled Stair


BIM and Manufacturing
Assembled Stair

I mentioned that session is for Expert but after I start my session I understood we don’t have any audience with depth knowledge about Inventor in room.

Karbandi Model
Karbandi Drawing

Then I asked is anybody familiar with Inventor?! Respond was terrible, just one person had little experience with Inventor. Important things is my session was about Building Industry and as I understood at least here ( Singapore ) we don’t have many people who are using Inventor in Building Industry.

Decorative Shelf Model


Decorative Shelf Drawing

After that I make decision to write and talk more about what we can do with Inventor in Building Industry. Also I want start new serious of post for teaching Inventor to all of my blog readers. And in the same time I will explain about what we can do with this software.



I had short discussion with Phil Lazarous from BiLT Committee and he preferred a blog with name ” Re Invent Revit ” . But I don’t want to make new blog, because currently many of my readers are from Building industry and they are involving in BIM Process and i’m looking for this people, why I should create new Blog.


Hence, I will go for this serious at this blog and I am writing about this with name “Re Invent Revit”

I will provide many file for practice, then you can use Inventor 2018 Student Version (  Autodesk is very generous ) if you don’t have subscription account for Autodesk Inventor in your PC or Laptop.

Mullion Profile and behavior with Curtain Wall Panel

Good night every body,

after 4month i think it’s the time i should write again,

I think many of us had some difficulty according to Mullion Profile and Curtain Panel.

Let’s see what is the problem, take a look to the below picture, as you see we have profile with more than one slot.



According to that profile we need to provide curtain Panel with two solid panel like below picture, distance between two panel is around 20 mm.



Now if we make upload this two family inside of the project and make curtain wall and mullion according to that we will receive resault like the below picture.

Ok, how we can solve this problem? we have two method:

  1. For solving this method we should add one parameter in Curtain Wall Panel, like below picture.


With this method every time according to different profile with different depth we should make adjust “Slot Depth” parameter for our Curtain Wall. And this is boring.

Then first problem is Manual Adjustment and also we have another problem, if we have different Profile for horizontal and vertical with different Slot Depth, we should add parameter like Slot Depth Vertical and Horizontal for Curtain Wall Panel.

Method 2:

for Method 2 we can do all of things automatically and we don’t need manual adjustment.

Lets see.

Important things is, we should understand why Revit is making model for Curtain Panel until to certain location, like below picture.

If you take a look to below picture you can see we have two Reference Plane as Origin Reference Plane.


Both of them are sensor for define limits of Curtain Wall Panel Modeling. That means is the first line has intersect with Front/Back Reference Plane are that two line in the above picture and because they have intersect with Front/Back reference plane Revit is making decision about Limits of Curtain Panel until to this two Line.

Lets change the Profile and see what is happening.

As you can see in below picture i tried to add new lines like the below picture and this time Front/Back Reference Plane is Sensing different limit line.


Let’s make upload this profile inside to the Project and watch the result .

Ok, i think until know you understood what we should do.

Just make change Front/Back reference Plane like below picture, and add parameter according to that .

Select Front/Back Reference line and make turn off define origin.

Create new reference plane and make Define origin for this.


Add one parameter ” Offset From Origin” and make setup according to the line of Slot. make upload your profile inside project.

You will receive result like below picture.

Go for Edit Mullion and say -30mm for offset.

Now you can try for any slot Depth and you can see everything could be ok.


Also you can change the value for “Offset From Origin” parameter to more than half of Profile Width and this will give you gap with zero distance.


ok, Good luck

I’m happy after long time i wrote something.

Room Legend with Full of Information



2 years ago I was a member of Iranian Group in Telegram Social software, I saw a question about the Room Legend with all of information that we need for explained exact space with name , area, perimeter, Number and etc…

I tried to find the best answer for this question and I found this workflow, which could be very useful for everyone who need to this type of presentation.

For explain this workflow I used a simple project with to Floor plan , GR and ST 1.

In Regular workflow you have Room Legend like the below picture.




Try to make new Color Scheme with the Number Rule.






Now you should create new Schedule for Room , You can follow the rule like the below picture ( Very Simple )



Make rename for new Schedule and call this one for example (Room Legend GR)


For visibility management per Level you can use Filter Tab and try to filter the list according to the Level GR. Like the below picture.


Make change in the Sorting/Grouping Tab to by Number.


You can try same method for next level and change the Filter rule to ST 1.


Go to the appearance Tab and change the item like the below picture.



Now go to the Sheet view and add Schedule that you prepared for GR.



Select the view and make active the view, go to the Color Fill Legend Type properties and make change the Swatch Height for 7mm .


Now you can go to the Schedule view and make hide the Number Column like the below picture.




Do the same for next level, You have nice Room Legend with all Information as you need.




Good Luck.

Curve Mullion with Revit

Hi again,

let’s check how we can create curve mullion and panel with regular tools in Revit, honestly I have not enough experience to do this with Dynamo and every time I want to create any thing which is unusual I try to do that with Regular tools.

We have System Family:Curtain wall in Revit and this could be very useful for many shape of modeling , but as you know panels are not curve for curtain walls.


If you add Mullion for curtain wall you can see Mullions are not Curve too.


For fix this problem we can use simple trick, this could be fixed with Basic Wall type in Revit.

Every thing you need is just create a wall with thickness like 2cm and then change the material as glass.


Go to the Edit type Properties for Curtain Wall and make change for Curtain panel to the new Basic wall , that we called Glass.



Now we have Curtain wall With Curved Panel and I can say some useful tricks at this situation.

Because of the base category for Curtain Panel ( Which is Wall Category ) you are able to use Door and Window over the Curtain Wall.

Another things is about the Opening, you can make any type of opening and place them over the curtain wall like the below picture.


Also, you are able to use Edit profile command like before without any limitation. ( if you create any curtain wall panel family then try to use Edit Profile command then you miss some panels )


Ok, Next step is about the Mullion, If you try to add vertical Mullion everything is ok, but for Horizontal Mullion no.


This problem could be fixed with Simple Sweep Shape in your Wall Type ( Glass )

You can create simple shape for Mullion Profile Like Rectangle 50×150 and make some adjustment for position like the below picture.




Perhaps you are thinking about many sweeps here but we need just one sweep.

Then create a sweep in the Edit Assembly Dialogue and make change material as Aluminum.

Go to the 3d View, Select the Wall and make some edit like the below picture, Change the Horizontal Grid to Fixed Distance and Horizontal mullion to None.

Now you have good result as you can see.


For top panel of this wall you can use two different way.

First: You can create new type of Wall sweep with Profile 50×150 and use this sweep manually over the top edge of curtain wall. ( I prefer this )




Second : you can create another wall type With two sweep with the different Constraint at the Base and Top like the below picture.  Then you should change the Top panel manually to the new Wall type.


Final step could be about the Schedule, if you create schedule for curtain panel then you have exact with for each panel, horizontal mullion length is the same with panel width.

But you should be careful about the Panel Area Because for the Sweep With. You can create Calculated value for Panel Area like the below picture.



And final Schedule could be about that wall Sweep Length.

Good Luck.
