generative modeling for Rhino
What I would like to do is be able to query the length along a curve from a point on that curve back to the start (or end) point. I thought there would be a component that acts like the reverse of the Evaluate Length component, but I can't find it.
How would this best be done for one or multiple points?
SubCrv was one of the ways I was looking for and had not found it - I was looking in the wrong place - thanks for the reminder. Still seems like a lot of components needed to get this data though...
Ahh, Evaluate Curve has a length to start output... That's really what I had been looking for from the beginning, and somehow I didn't find it... Thanks taz! Oh, and thanks too for reminding me that you can reparameterize the curve inside the component...
The parametrization of a curve does not necessarily correspond 1:1 with its length - except where the curve is a straight line... So you can't just multiply the parameter of the point on the curve with the overall length... Also if the parametrization is other than 0 to 1, this will not work...
