Grasshopper

algorithmic modeling for Rhino

Hello. will you please help me out with this one. I can't figure out.

I have got base curve 'A'

I evaluated point on the curve.

But as per Curve 'C' I was not sure how can I have a line from start point of the curve to the Evaluated point, so that the length of the line changes as I change the parameters of the evaluated point on the curve.

If you want to shorten a curve based on length, it's easiest to use the extend curve component and use a negative extension length.

If you want to shorten a curve to a specific curve parameter, you'll probably need subcurve or trimcurve or something. I'm on an iPad without access to gh and can't remember what it's called.

Hello David,

Subcurve worked. Thanks a lot for your reply.

Regards,

M
