I`m using Windows version:
Version 7 SR28
(7.28.23058.3001, 2023-02-27)
Why preserve “other end” in match curve command doesn`t work for me? Is that broken?
The first and last points are G0 with neighboured curves.
please share the file containing those 3 curves.
my guess:
the middle curve already has 5 or 6 CVs - so the preserve other end option will not have any affect.
the preserve other end option will increase the degree of the curve to get more CVs.
1st CV = responsible for Position
2nd CV = responsible for Tangent
3rd CV = responsible for Curvature.
so for example if you want to match a single span Degree 3 curve with 4 CVs - and you match by Curvature and preserve Curvature on the other end - you will get a Degree 5, 6 CV result.
(3 CVs for each end, to match curvature and to preserve curvature)
kind regards -tom
The middle curve has 4CV because my goal was to set tangent on both sides (2CV on the left and 2CV on the right). I think it was done right.
Is that working on your v7 Rhino well?
ok.
but if you set
match = tangent
preserve = curvature
you should get a 5 CV Curve ?
why do you thing something is broken here ?
if you want to match both ends, you have to run the command twice - one time for each end of the curve.

To expand on Tom’s comment: Rhino does not have a tool for matching both ends of a curve simultaneously. “Preserve other end” keeps the requested characteristic at the other end of the selected curve from changing as the curve is modified for matching. It is independent any adjacent curves.

Ok. I`ve thought that it works for both ends of the curve not only on one. Same as matchSrf.
Thanks a lot. I think it would be a lot faster if I would need to click match only once per curve (not twice).
