i have a part that was created in rhino, and exported as a 143 iges, and i have it stitched together in dwg and ipt formats. however, my problem is that i need to dimension the complex part. i have been trying to get drawing views for the part, but when i select the ipt file for a base view, it says "cannot create drawing views for empty model documents."
as far as i am aware, the part is completely stitched together as a solid (the part has grey, opaque faces. no transparencies), but the mass and volume properties say that it has no mass or volume.
i hope someone can help me.
thanks
