Re: 2D symbologies for BIM projects

Are you referring to a case similar to that of Revit, that when you add a 3D switch object, when cutting to make the technical part, it already gives me the symbology?

About hybrid 3D/2D objects, that's certainly a possibility at some point. Many BIM apps do that. Honestly I'm no fan of it, it is not supported by IFC, and it seems overly complicated while there might be many other possibilities to achieve the same result (have a different object in the 3D view and in the 2D view), maybe even some more interesting.

Basically we need something that says: "this object's shape must be switched with this other shape when viewed in that section plane"

Yes, something like that. For example: An arch object would have some sort of "2D Representations" property, which could contain several things like "Top:Shape006", "Front:Shape004". If that object is seen by a horizontal (top view) cut plane, the Shape006 would be used, instead of actually cutting the 3D object.

I was here researching more on the subject of symbologies, I have now done it for the new Fire Prevention course. Then I came across this video of a girl configuring the symbology on the object in archicad. of course with FreeCAD it would be executed in a different way, but I think this logic is very interesting.

Here are some images from the Fire Prevention library.

Therefore, the library of 2D symbologies in Draft is increasing and will soon be composed in the Macro created by Eng Maykon to insert in a simple way:

I've already highlighted it here and even a campaign to run 100% is an official tool of the BIM bench (laughs)
