Input is empty/no closed volume found
Hi, guys. I'm facing a basic problem that hinders me performing the next steps.
When i try to mesh the igs. file exported from Rhino, it always shows that the input is empty.
So i suppose that the file is not a solid, then i use the 'bounding surface' to make it solid.
It shows that no closed volume found.
I can't figure out what mistakes i have made.
Please help me, thanks!
