TweenCurves not always working

Hi There seem to be a few cases where TweenCurves does not work as expected. Here’s one examplenotweencurves.3dm (82.5 KB). 2 simple lines, and TweenCurves tries to connect the endpoints.

This is in the latest build of V5


Hi Eric- I can see from a couple of similar posts that it is not obvious enough, but the UI tries to show you how the curves are to be tweened - see how that diagonal line shows? Click on the point at one end or the other of that line to flip the end-matching (the curves are in opposite directions) and you’ll get, I think, what you want.


I never realized there was an interactive aspect to that command!

Thanks Pascal
