Thank you Michael.

So if Larry decides to use CW vs CCW, the dies only need to be set up once, which can be done before tangent scripts are used...

The parametric order of crv.getTangentsToPoint( pt ) would be from circle start to circle end, around the circle. Or from arc startPt to arc endPt, around the arc.(?)
CW FLIPS to CCW (?)
