I walked away from the drawing for a break, came back, it was locked up. had a warning "unhandled exception" If I remember right. It generated a crash report. It on my desktop. it wont open for me? Maybe it sent it to IMSI? I don't know. The drawing is attached. I also noticed that some how, it doubled all my parts up. So, if you click on one sheetmetal roof panel, now there are 2 in the same position to choose from? Used to be one?
You did something that, while possible, is not the usual way we do things in TurboCAD. The Polylines that you converted into the (what looks to be) fiberglass roofing was done by applying a value in the 3D / Thickness
setting under the Properties
Normally, when we convert a 2D outline to a 3D object, we use Simple Extrude
(different commands are used when using two 2D outlines to create a 3D object).
I rarely use the Thickness function, so I honestly don't know if it will cause the type of problems you are seeing, but it was recommended that I avoid it for what I was trying to do when I was getting used to the software lo, those many years ago.
