Curtain wall `Element Bounding Geometry` outcome not as expected

Hi there,

While using Element Bounding Geometry for curtain wall;
As image shown below, 2 elements are identical but only base level different,
the Bounding Geometry result differently… Any ideas?

I’m seeing this as well, thanks for reporting. Its adding in the levels below to the overall height for some reason.

Using a bounding box with a plane derived from the Element will give an accurate representation.

Hi @Japhy
The bounding box method may not work with a curved curtain wall condition, hopefully it will get resolve soon :grinning:

Just found its the same result for Basic Wall type.

Yes, this is a bug and in the queue to be fixed.
