Built-in models created with GeometryCreationUtilities cannot be edite

[Anonymous]

I used GeometryCreationUtilities to create a built-in model, but the created model can't be freely edited like the model created by the Revit interface operation. What is the cause?

Maybe you can find out yourself by exploring it in depth with RevitLookup?

Yes, it is not built-in model created by revitlookup. It seems that revit api does not currently support the creation of built-in models.

Hi,

I think you are talking about some sort of DirectShape elements.

DirectShape has been introduced for import purposes.

Using DirectShape, you can write *any* import tool, coping with arbitrary formats.

But on the other hand, the generated elements are static, their geometry cannot be modified by user, as you have seen.

In-place families *still* cannot be created via API (as of Revit 2020).
