I will give that a try, what a pain though.
I tried my idea of ChangeDegree then -_Rebuild but it lost the tangent CPs at either end of curve. so -_Rebuild master doesnt keep tangent aspect of MASTER. damn !!!
I cast lines across from my original 5/8 curve and dragged the control points to them then proceeded to nudge them until the curve visually matched the offset one. It does not take 30 control points to recreate the offset 0.5 curve so why offset has done this to me is annoying. 10 mins per curve and 13 more to do.
apart from my V5 now acting up and not letting me know when I have selected something, I managed your method though it also loses the tangent control points in that they are angled and need putting back, and then tweaking to match curve.
I have several curves to do and two halves for each. all my hard work being done all over again. This has to be wrong.
I did try for joining the two halves of my curves together (egg shaped profiles) but extend surface doesnt work when they are joined, so no shortcut there, that would have retianed the tangent controls if it was possible. Why is that ?
I had also scale 1D’d every profile so I have that to do all over again as well.
when I use offsetSrf on a model it causes all sorts of issues, naked edges, holes etc and minute twisty aberations, I didnt think it also attacked healthy curves.
from your linked thread… Learn a great ‘hack-nique’ for off-setting clean curves with equally clean new curves, as opposed to the usual complicated mess. These cleaner curves will make a huge difference in creating higher quality organic surfaces.
This needs fixing please McNeel.
