I am not more experience in artcam , I input and work 3d models thru auto-cad,SketchUp, or 3d max and export to twin motion the enhance the graphic and render and fast walkthru animation 

I am not aware as I use other world standard tools.

Save your 3D drawing in PDF & then import it in artcam

any type format page he need for page net 

Artcam usually work with textures and images at its best, if you wish to import the drawings i suggest to export those drawings as a PDF and then try to import in artcam. You will find this approach more reliable and fast for your 2d drawing to 3d conversion.

Scan it using any sort of a scanner :)
