Circle/Diamond/Square

This is a NAS 979 circle/diamond/square with an inverted NAS 979 cone test in the center. This part was used for early STEP-NC testing forums and both three and five axis versions have been used.

The STEP-NC file includes geometry for starting piece, final piece, and tools, toolpaths for roughing, finishing, and tool parameters.
