Thanks so much for the help. I’ll attach a sample file.

Basically what I’m doing is trying to reorient a bunch of head models that I have. I have three landmarks on the mesh I use for this, A_Tragion_R, D_Tragion_L, and B_Infraorbitale_R. I’m using two points on the y axis as targets: Align Right Tragion (A_Tragion_R -> Align Right Tragion) and Align Left Tragion ( (D_Tragion_L -> Align Left Tragion). Ideally the midpoint of A_Tragion_R and D_Tragion_L would be at the origin, but for some reason its based on Align Right Tragion (not a huge deal since I could translate everything afterwards so that the midpoint is at the origin). I then rotate the scan+landmarks so that B_Infraorbitale_R is in line with the x-axis line. I made 4 layers: sample (which contains the mesh), Landmarks (contains the 3 points), FP_Align (contains 2 points and a line), and Aligned (which contains the mesh and landmarks oriented to give you an idea of what I’m getting at.) (Side note: I can rename the 2 align target points if spaces in the names are a problem)

I have many more points on my project meshes, so picking these specific points out away from a highlighted mesh can be hard to see. Since my naming of the points is consistent, i was hoping to use that to my advantage.

Thank you so much! Would be open to suggestions if this process seems backwards.
