Curve curve projection

I know this was brought up before, but I’m running into it a lot today. It would be great if Project accepted a curve as the thing to project onto. Curve curve projections would result in a point.

Thanks,
Sam

I think I’m really dense today, but how, in general, would a curve “project” onto another curve? Do you mean that the tangent at one end just happens to point directly at another curve and you would like to know where the tangent would intersect the second curve?

Oh, wait! Do you mean coplanar 2D curves?

Hi Sam, yep, I have heard this before, and I think I made a script for it- I’ll see if I can dig that up for the short term anyway.

It’s an oldie but it seems to work.

Ooo, a 2007 vintage :wink: Thanks Pascal

Hi Pascal - any chance this functionality could be integrated? I haven’t used the script you posted (I may try it), but I’ve had to do this for years. The workarounds are easy but time-consuming. It could live in Curve->PointObject->Project Curve on Curve. I suppose it is not quite as trivial as I had originally thought (since there are some weird cases to consider, such as identical curves, or partially identical curves). The result would be 0, 1 or many points… Just a thought! Cheers, Tom
