Hi again Rich,
Try SECO, they have a CAD site full of DXF, next best to solids I suppose
SECOtools
As a suggestion start your search simple ie
c5- sometimes a space or letter in the wrong place stuffs the results

Just checked Sandvik, they only have what I've just suggested...DUH
Just querying.. CAS uses STL ( a very coarse STL ) does it not ?? You may have to mod a DXF to a solid
