BiMTOOLS Dimensioning


I am trying to use the auto dimensioning tool from the BiMTOOLS 2021 Add-in.
I use curtain walls as window, which seems to cause the tool to not function correctly. Only 1 overall dimension is shown. As a test I created a new job with simple walls and window elements, the dimensioning tool works. As soon as I add a curtain wall, it does not.

Does anyone have experience using the tool?
