i am reading here for some months and the forum helped already a lot. thank you all.
but now i have a problem i cannot solve and ask for help.
i am trying to flip the end of curves upwards for a ramping profile for cnc engraving. the ramp should follow the curve.
i was able to make a working grashopper design. but sometimes the design does not work, i suspect when the rhino curves were trimmed or mirrored or manipulated with the control points before importing into grasshopper.
attached is a simple example of the curves. the above ones were manipulated with control points. under them are three simple nurbs curves.
i divide the curves, then shatter them. with the manipulated curves the result is not correct, with the nurbs curves it is correct.
does anybody know why that is?
thanks for your help,
