Brian made corrections to post 11632.34. MoI v5 API does have those two methods documented.
PEER had made the additions some months ago.
I do not know how or where they learned of the new methods.
I had an old copy on both computers.

For closed curves, the GetTangents script( crv, dir ) will place an extra tangent point at the end of the curve (if it exists there).
I guess I can add code for if crv.isClosed, reduce params.length by 1, and not do the extra horizontal or vertical tangent point (if it exists there), for the end of the curve.(?)
To be tried later...
I need to learn about how this curve parameter thing works...Are there any recommended (NURBS?) references or forum information??
