VCarve Pro only imports the calculated toolpaths from a V3M file and not the
actual 3D model. So as Chuck said, you first need to,
Open a V3M design in Vector Art 3D Machinist
Specify the required sizes for Length, Height and Thickness
Calculate roughing (if req'd) and finishing toolapths
Save the V3M file - ideally with a new name to prevent overwriting the original
The new V3M file can then be imported into VCPro.
The imported toolpaths can then be moved / positioned by
selecting the preview image in the 2D window and dragging
or aligning this as required. The associated toolpaths are
linked to this image and are moved to the same XY position.
I hope this makes sense and help,
