We have a file at my work of one of the machines we sell. They want to do an animation of how the machine works...in steps Carrara, right? The file we have is a CAD .dwg file. I had someone convert it to a .dxf file to import into Carrara. When I open it, I get nothing. I have downloaded .dxf files (from 3D Cafe) with no problems. Is there something in the way the dxf file is saved? If anyone knows I would be very thankful.
