3D Measurements > Surface Measurements
Surface Measurements allow you to make measurements from the currently rendered surface(s).
- Positions: Measures the X, Y, Z coordinates of each point on the surface
- Curvatures: Measures the local radius curvature (in um) at each point on the surface . The averaging radius controls the extent (in um) to which the surface positions are averaged prior to the local curvature calculation.
- Thicknesses: Measures at each point on the surface, the distance to the other side along that point’s local normal
- Normals: Measures the local normal at each point on the surface
