If your AutoCAD file only has lines, arcs, etc, then export as DXF
If you have solids and/or surfaces, try using STP ( this can be imported into Mcam and then get your wireframe geometry from it ( create curves on 1 edge, or all edges )
IGES will work, but it may be awkward getting user-friendly from it as it comes in as a tessallated mesh ( triangles )
if creating geometry from surfaces, you will double-up on curves ( best to get them from the solid )
PS-- there is also a Mastercam forum here for further info/searches |
