I have a purchase part that I downloaded, and is part of my machine. The downloaded part is all imported surfaces with some surface bodies. I need to do a cut section of my machine on the detail print, and when I section through this imported surface part, my cut section shows errors. I can hide the part in the view, but still get the errors. Converting it to a mesh body just slows my system way down. Is there any way to ignore the surfaces in this part when creating a cut section of it on a drawing? What's weird is I can do a cut section in the 3d model just fine(most times that doesn't work for me with a surface model).
