I am just passing this weirdness along, as it happened to me.. and I resolved it (sorta).
I have elevations of 4 sides of a home. All has been well while working on the project. Turned vector hatching on "south' elevation.. normal. Turned vector hatching on east.. frozen solid. North.. fine. West.. frozen solid.
So, one direction fine.. one freezers AC and results in a force quit. I tracked it down to one composite wall. Isolated the wall and sure enough, generating an elevation of the end condition freezes AC. However, for whatever reason I was able to delete the wall, and redo the same composite and it is ok. I don't know.. but something is not right. On the attachment, only the block/brick wall froze AC, but not aftrer deleting it and replacing it "fresh"????
Moral - if AC is crashing with vector hatching on while generating an elevation, look for an end wall condition.
During this, all 3d's worked fine.
If any commits, I might not see them for a few days.
