RTC Events Singapore 2017, 2nd Abstract Steel Structure Detailing with Autodesk Inventor and iLogic Parts

This is my honor to be a part of RTC Event 2017 in Marina Bay Singapore as a speaker.

In my opinion Inventor is one of the best software for customization around what you want as a fabrication modeling and documentation. Because of this and because of many other ability that we could find on this software, I used  this software for Steel detailing. Combination between regular modeling and iLogic ability gives us huge power for complex job like Shop drawings.

If you are interest to be attendance at this event I will say welcome to you and I hope to see you in RTC Event 2017, Singapore at 30 March – 1 April.

Also, thanking the RTC Committee , Richard Kuppusamy  , Heidi Lam and Phil Lazarus for what you are doing as a volunteer for RTC .



Taking Stair from design to fabrication with Revit and Inventor, just in 10 minutes.

Many of my friend in the fabrication industry asking me about the workflow for making documents for stair fabrication.

I refer them for using Autodesk Inventor because of ability of this software.

At this post I want to show you how it could be simple for Revit and Inventor users to create an assembled stair with full of detail just in 10 ,

Let’s start,

What we need as a material is very simple, First step is design what you need with the precise overall dimension in Revit and this could be very easy in Revit. Like the below picture I create an stair with spiral shape between two level with 3.24 meter height.

Stair Width = 1 m

Stair tread Depth = 0.3 m

Maximum Riser Height = 0.18 m

Stair stringer Size = 0.05 m x 0.4 m

Structural Depth on Run = 0.15 m

Structural Depth on Landing = 0.3 m



you can use Isolate command in the project area for which stair that you want create detail.

Go to File > Export > Cad Format > ACIS *.sat

Now Start Autodesk Inventor and open SAT file in Inventor as a Part with multi solid body


Make sure about where you are saving the file.


The result should be like the below picture. you can save it with ipt format.


You can create regular helper object ( Work Axis and Work Points ) for the future modeling like the below picture.


Create 3d Sketch like the below picture according to the Helper object ( Work Axis and Work Points )


Create two Sweep as surface according to 3d Sketch and two simple 2d Sketch like the below picture. You will need this surfaces for manage the sweep command for that profile you want create with Generative shape design tool.


Create a hole and make pattern from that hole with rectangular pattern like the below picture.


Create an iLogic part with several option that you need as a tread for stair and use this for final stair.


Create a new assembly and place that part you open as SAT format with multi body and saved with ipt format like part.

Now you are able to create structural frame for body of stair according to what you have in the basic model that you import from Revit and mange in the Part environment.


Now you can place the first tread as iLogic part and the dimension for this tread is depend to the basic shape of stair in Revit.


For the next step you can create pattern for this tread and use Feature pattern depend to the Hole pattern in the Basic stair part.


Now go to the IDW environment and make some drawing.


This is very fast and unique workflow for everyone who looking for fabrication in stair category.








Enjoy this.


How you can Create Timber Wall with precise Schedule and good presentation ?

At this post I want show you how you can create Timber Wall in Revit and I will follow two important things :

First is precise schedule Like volume of the wood or quantity of Timbers and Length for Timbers.

Second is Good presentation in the 2D and 3D View.

Page 10 B


perhaps you make some guess for this wall but if you want to go for do this with wall Sweep I can say you are going wrong because you can’t create schedule for which Wall sweep then coming from the edit structure Layer of the wall , another things is you should create thin layer in the Wall Layer dialogue box for create wall sweep in the height you want, this layer make your wall wrong.

Ok, Lets start

First thing is wall and you can create a Wall with thickness equal with the Timber Diameter For example  200mm

Timber 2

Then you need to Create 2 Profile for Reveal in the Edit Structure dialogue box.

Timber 3

You can see two circle for Timber separation in the below picture.

Timber 1

Now you can create some Reveal into the Wall structure like the below picture.

Timber 4

You can see what happened for your wall.

Timber 5

Try to place Door and Window in the Plan View.

Timber 6

You can see what happened in the 3D View.

Timber 7

Select the wall and go to the Edit Profile.

Timber 8

Like the below picture and hit the Finish button.

Timber 9

You can see the Result.

Timber 10

For the final part you can use Design option and make copy from the Walls without any door and window.

Timber 11

Then you can use Create Part command , you have good result and if you select any part in the project you can have access to what you need.

Good Luck.

How We Can Create Stud Behind the Ceiling and Plaster board Panel of Ceiling in Revit ?

Hi I was a business trip in pas 3 days and now I came back , Lets start new trick

As I said before Sloped Glazing Roof is amazing tool in Revit , then for this trick we want use this command for Stud and panel in the Ceiling System.

I prepared all things you need for this method of Modeling :

  1. Profile for Stud ( Profile Type : Mullion ) with two Type .

you can see Type A in the below picture and as you can see this profile is connect with the base reference line of Profile Family.


Ceiling 17


you can see Type B in the below picture and as you can see in the ark ( 2 ) we have distance between Origin and bottom of Profile .

This distance is equal with the Width of the Stud Profile.


Ceiling 18


3.  Load the profile into the Project and use them for new Mullion Type as you can see in the Mark ( 1 , 4 ) and change the Profile family for each of them.

Ceiling 21



4. Another Part is Hanger for Stud. You can use Curtain Wall Panel for this.

Ceiling 19

5. Final Part is Plaster board panel and for this part you can make duplicate from solid panel and change the properties for panel like the below picture.

Ceiling 20

After preparation for this parts you need to make four new type in the Roof Sloped Glazing Type .

Type 1 ; Call that Mullion A and change the properties like below picture.

Ceiling 22

Type 2 : Call that Mullion B and change the properties like below picture.

Ceiling 23

Type 3 : Call that Hanger and change the properties like below picture.

Ceiling 24

Type 4 : Call that Hanger and change the properties like below picture.

Ceiling 25


After all preparation you can start with the procedure I will say in the next . I should say at this example I create base ceiling for project before I start to create stud.

Select the ceiling ( 1 ) and select Edit Boundary ( 2 )

Ceiling 1

Select all of the boundary line ( 1 ) and select Copy clipboard ( 2 )

Ceiling 2

Create new Roof by Footprint ( 1 ) and go to the Past drop down and select align to current view ( 2 )

Ceiling 3

Click on the Finish button , Select the Roof ( 1 ) change the height for placing the roof behind the ceiling ( 2 ) and select Copy clipboard ( 3 )

Ceiling 4

Hit the Align Same Place for 3 time to have 4 Roof in the same Place .


Ceiling 5


Select one of the Roof and change the type to Mullion A

Ceiling 6

Select another one and change the type to Mullion B

Ceiling 7

Select the third one and change the type to Panel 1.5×3 Meter

Ceiling 8

Select the Final one and change the type to Hanger

Ceiling 9

Select Delete Type

Ceiling 10

and then Select Replace Type.


Ceiling 11

Make your view as Isolated View . ( For selecting this panel I used Single Select method but for big boundary you can use Filter )

Ceiling 12

And change the type to Empty Panel .

Ceiling 13

Like Below Picture.

Ceiling 14


You will see your Stud System perfectly in the Project and other information like the shape of Panel and quantity of Panel.

Ceiling 16


Good Luck.


Quick trick, How you can create boundary for front view of wall when you have Sweep on that ?

Did you ever use Wall Sweep for your Wall in the Project modeling ? You can add many detail into the wall model but you have many limitation with this tool.

For example if you use Wall sweep in the edit structure dialogue then you are able to add many wall sweep simultaneously into the wall and all of them creating automatically , but the problem where coming you want to create schedule from this wall sweep , you are not able to  create schedule for this type of wall sweeps.

But if you use Wall Sweep Command every thing is different , you can create schedule for this but you can’t create many of them simultaneously in the project area.


Other problem for both of them is about the font view of wall , in the normal wall which has not any wall sweep you can use Edit Profile Command for change the boundary of the front view for your wall , but you can’t use Edit Profile Command for this type of Wall !!?! maybe you think you can do this , pay attention what is the result for the final model of wall?? could you cut your sweeps as you want ?? with the shape you want ??


In the Next I will explain how you can solve this problem.

Let’s start, I prefer to you create four wall and use Edit Profile command for them like the below picture as you see every thing is ok.

sweep 1

Then make a copy from them and change the type for this walls to another type which has wall sweep. You can see what happening when you have wall sweep into the wall . every thing is for cutting wall sweep are wrong.

Sweep 2

If you select a Wall for example like the below picture and go to the Edit Profile you can see the boundary line.

Sweep 5

And when you finish Edit profile command if you select the wall and pay attention to the Wall sweep point you can understand what happened . In fact the wall sweeps are finishing in the intersection point between the boundary line and guide line of wall sweeps.

Sweep 6

Go to the Edit structure dialogue and check the wall sweep and option for them like the below pictures.

Sweep 3


Sweep 4

Now we can fix this problem very simple. go to the Model in Place area

Sweep 7


You can choose Generic Model


Sweep 8

Run Opening Command ( 1 ) click on the ok button for choosing host of opening ( 2 ) and select which wall you want ( 3 )

Sweep 9

Create your own area s you want and then press Finish icon.

Sweep 10

Select Finish family too.

Sweep 11

you can watch what is the result for your wall, every thing is ok.

Sweep 12

You can do this as the same way for other walls.

Sweep 13


In fact you can add some parameter for which wall has wall sweep in the Edit dialogue of wall and get the correct result for scheduling sweep material.

Good Luck

How we can create drainage system in Revit ?!?

Ok, I saw many people , who are creating drainage system with model in place tool and in my opinion they are working too much for doing this.

Now I want show you how you can create drainage system more than simple then you can think.

All thing you need is a Wall and a Profile.

Let’s start.

Create New Wall ( 1 ) and go to the Edit Type ( 2 )

Drainage 1

Create Duplicate form the Type and Call that Drainage System

Drainage 2

Make change the Thickness for this wall.

Drainage 3

You will have wall like the below picture.

Drainage 4

Now you need to create a profile for Reveal like the below picture and change the usage to reveal , load this profile into the project area.

Download Family : http://s7.picofile.com/file/8259765142/R9.zip.html

Drainage 5

go to the Edit Type and add Reveal for Wall like the below picture.

Drainage 6

Now you have new Drainage wall in your project and good information then you can use for schedule and you can count your Walls in the project area.

Drainage 7

Go to the plan view and Run the Wall Command , turn on Radius option and change the value for Radius .

Drainage 8

Create your Wall .   What you feeling now ????

Drainage 9

But something is remaining , What happen if you create branch from the main line ?

Drainage 10

Go to the 3d View for recognizing the problem. How we can fix this?!?!

Drainage 11

Drainage system is very similar to Duct system, then we can create some Fitting part for this system and this family can fix the problem for us.

You need to create family like the below picture. the family should be wall based.


Drainage 12

Load the family into the project area and place the family in the floor plan view and change the branch angle in the Instance properties dialogue .

Drainage 13

Now you can use Align command for aligning between wall center line and the reference plan of the fitting.

Drainage 14

Go to the 3d View and use join command for joining the family and wall together.

Drainage 15

For cross section you have same problem .

Download family : http://s6.picofile.com/file/8259765100/Cross.zip.html

Drainage 16

And you can use same method .

Drainage 17


Drainage 18


Drainage 19

At the Final you have every thing you want , Fast modeling , Precise schedule , Fast Editing , etc.


Good Luck



Just Experience sharing , Steel Structure Detailing with Autodesk Inventor Professional !?!

I Said before my opinion About the Autodesk Inventor Professional.

Then three or four years ago is start to create my own plugin to build steel structure with Inventor Pro.

And I did some project with this plugin , Autodesk Inventor is very useful and very powerful for modeling.





I Send This Proposal For AU Las Vegas , but ……

Good Luck.
