As title implies, so it seems to be.
I cannot reproduce your issue. I tried to execute the vaExtractSolids command in a wall inside a block, inside Block Edit. Is that what you’re trying to do?
That’s correct, and I could reproduce the issue reliably on a version of the project I an working on. I can’t seem to find that version, so I’ll just have to keep my eye out in the future for this. It seems to be working now.
