Hi, I’m trying to make wire frame on surface. I used command contour, but contour lines are messed up.
I want to make frame of curtain wall like sketch. Does anyone know how to make it?

Hi @ryu
You are a long away from W0,0,0 which tends to cause trouble for some commands.
Your units are mm and your tolerance is set to 1. This might also cause trouble.
There are a couple of duplicates joined to themselves.
There’s a bad object in there as well.
Your surfaces overlap themselves in multiple areas.
Almost none of the surfaces match, so there’s a ton of naked edges (meaning any sections you make will not be closed curves but open segments).
There’s a LOT of cleanup to be done before you can get clean contours from this
