Well i tried it and did get a prinatable item.

But all the back and forwards in the menu system was confusing, and I could not get my head around how to make the object thicker without changing all the other dimensions as well.
Also the add hook menu system was almost unuseable and I gacve up on trying to get the loop aligned. Just could not move anything consistently in the direction I wanted.

To be fair I was just trying to turn a black and white drawing into a printable object - I wasn't trying to make a pendant.

And it did sort of do that.

But I think I'll learn how to use inkscape to make dxf files in future. It has to be simpler :-)
