Vertically Compound Wall - Adding Splits and Layers

[ari.monteiro]

Hi,

I need to write code to vertically cut the layers of a wall, as shown in the video below:

I found in the API documentation the Autodesk.Revit.DB.CompoundStructure.SplitRegion () method, but I don't quite understand how I can use it.

I looked for code examples on how to use this method, but didn't find it.

Any Suggestions?

I searched the Internet for SplitRegion samples as well:

https://duckduckgo.com/?q=revit+api+%22splitregion%22

I did not find many examples, but here is one that looks pretty useful indeed to me:

On closer examination, I discover that the sample I found is part of the Revit SDK:

• .../SDK/Samples/CompoundStructure/CS/Command.cs

You should always search the Revit SDK before going anywhere else, you know.

The samples there are created and shared exactly for this purpose and no other!

Hi @jeremytammik !

I didn't really look at the SDK examples, but here in the forum. I'll remember to look at the SDK first next time! Good hint!

I will try to use the codes in the links you gave me.

Actually, I'm trying to solve my problem in Dynamo using a Python Script node.

But, I also know C# and my idea was to know how to solve my problem in C# and then transcribe the solution to Python in Dynamo.

Thank you!

Merry Christmas and Happy New Year, my dear! 🙂

Hi @jeremytammik!

I used part of the logic you provided me last year.

https://csharp.hotexamples.com/examples/-/CompoundStructureLayer/-/php-compoundstructurelayer-class-...

But there was a question: is it possible to edit the split dimension programmatically (see figure)?

I need to change the material and dimension of the wall split.

I've already verified that I can access:
    1. Access Wall Regions = GetRegionIds ()
    2. The layer associated with region = GetLayerAssociatedToRegion ()
    3. Material associated with layer = SetMaterialId ()

How can I change the region dimension from RegionId?

I did not find in the API documentation a class for manipulating the region in the split wall context.

Thanks!
