Clothoid 2 point curve script

Hi Michael

Is there some way to get the end point tangent of a curve, by script?
I was thinking of correcting the interpcurve version of a clothoid curve between two existing curves, and to
correct the slight errors in the beginning and ending tangents by doing a MoI Blend between the start point, and the second interpcurve point,
and also a second Blend between the next to last point, and the end point.

Or maybe there should be extra points between the beginning and first point, and also between the next to last point, and the end point?

I have read that for these types of curves, it is not possible to perfectly display the curves by NURBS, but only to within some tolerance?

Also wondered if you will be improving the slide bars for scripts, as the sliders that you do for your factory commands work so much better?

Thank you
