Unfortunately it won't run on a PC, without emulating a Mac. Yuk.
As bad as running a PC application on a Mac with an emulator, even
worse.

Use Amapi, it costs 1/2 of Rhino, and comes with both Mac & PC
installs on the CD.

CAD= Computer Aided Design, which both Rhino and Amapi fit exactly.

CAD <> (does not equal) AutoCad Look alike interface.

For radially shaped parts, it may be possible to use the Vector
unwrap cylinder function. This will work for cones and cylinders, but
the math is only a step away. Circumference=PI*D For a cylinder,
the length of the wrap is the same on both sides, for a cone, it gets
shorter. Draw the two sides, with a symmetrical center and connect
the ends to form a Trapezoid (a quadrilateral having only two sides
parallel). The parallel sides are the ends that will be wrapped into
a circle. Put a couple of tabs on the angled sides, cut'em/burn'em &
pop rivet them together.
