Hi all, Does anyone know of any tools (preferably free) that can extract and measure arc and chord lengths easily from 3D surfaces? I have laser scans (.ply, .obj or .stl files) from joint surfaces. I'd prefer something where I could "draw" on the arc of interest if there is such a program.
I also need a tool to find the coordinates of a centroid that lies on the surface if you have any suggestions for that. Thanks for your help.
