Need help with object conversion

[TheWebExpert]

I have a highly detailed .OBJ file, which was originally a 3DS Max file.  The file loaded just fine; however, when I converted it from Mesh to Breps, a lot of the objects were these things (), whatever they're called.  I need to be able to convert them to normal bodies so that I can cut, combine, etc.

Can anyone help with this?

Those are surface bodies (not-closed, infinitely thin geometry).  You will have to use the Stitch command in the Surface toolset to join them together:

if those surfaces form a watertight boundary, they will be converted to a solid body.
