Hello, I have a problem and I need some help.
I have some vertices of multiple polylines that I want to project onto a mesh. I’m not sure if the vertices are above or below the mesh. The idea was to use the Mesh|Ray component twice: once with a positive Z vector and once with a negative Z vector. Each vertex should have only one intersection. So, for each vertex, one Mesh|Ray should return a value while the other returns null. Then, I would add the two lists together to get all the intersections.
The issue arises when a polyline vertex is exactly on a mesh vertex. In that case, both Mesh|Ray components would return values simultaneously, creating complications in the addition process.
Refer to the table. Polyline {329} works as expected, but for polyline {330}, both ray and mesh components yield a solution at vertices 0, 2, and 10, indicating that the addition is clearly incorrect.
Do you have any suggestions on how I can solve this problem?
