Project curve projecting double at times, possible error

Hi,

I have a set of circles that I wish to project onto a surface. I also have a set of vectors for the direction to project into.

I wanted to know why I’m getting the projections in both directions.I tried reversing the vector as well, to no avail

Any help is appreciated, thanks!

you’ll have to cull using something like ClosestPt, or extrude and intersect. Since project goes in 2 directions always, the curves on the opposite side will also get projected.

I have done it for multiple branches, but I am only having problems with this specific branch. The other branches work flawlessly with just a single projection.

But I think I know what you mean now. The other surfaces I have are slightly angled so the projection isn’t reaching the other side.

Thanks!
