making Helical gear with fly cutter

[ozzie34231]

Don't see why not.
I don't know much about the various formats. I seem to remember that STLs are made of triangles and DXF probably can use true radii where they exist. While an involute gear might not have any radii, a timing pulley does.
If true, a DXF would be better for the timing pulley; don't know about the gear.
How does DXF handle the involute curve?

Ozzie:

I think youd want dxf in all cases. STL's are 3d shell objects, dxf is the only real way to get any accuracy on evolutes.
