Nope, don't understand at all. A picture is worth a thousand words to me. Hopefully someone with a few more active brain cells will be able to help.
I attached the .crv of the parts holder. Basically what I want to do is create some stepped sleeves from dowels by placing them in the parts holder. It would be nice if VCarve would allow you to put a 3D cylinder in the drawing then you could cut it out. Basically you would need two jobs, one would be the part holder and the other would be a dowel. To picture this would be a lego (spare piece with the little tabs sticking out).
This is a picture of the part holder. What I will do is place dowels in the cutouts and carve different steps in them. What I would like to do in VCARVE is actually place the cylinders (dowels) into the original job.
