Does the Geometry inside Families have their own boundingbox?

[MJB-online]

Hi all,

Does anyone hapen to know if the geometry inside families have their own (nested)boundingbox?
This would give me more accurate info about the element size (when elements/families are positioned non-axis-aligned in the project).

No they don’t

Any geometry has a bounding box - the question is more aptly this: is your family built in a way where you can easily isolate the geometry in question?

The revit api provides two separate methods of fetching the geometry of a family instance. You can either read the transformed geometry of the instance or read the “original” geometry of the family. Either way the result is a GeometryElement on which you can call “GetBoundingBox”.

Thank you very much @Dimitar_Venkov, now I have a nice study project. I’ll see how far I can get.

I thought I would need Python to do this, but OOTB nodes are sufficient. Thanks again @Dimitar_Venkov you certainly sent me in the right direction.
