Hello!
How would you check which points are on a straight edge, and then rotate them 90 degrees?
I know how to check if a point is on a straight edge, but I don't know how to rotate the normals to be perpendicular to the edge they're on…
Any ideas that might involve the VOP?

The steps I have taken:
1. Point normals to next point.
2. Calculate the dot product of the current point normal and the next.
3. Calculate the dot product of the current point normal and the previous.
