Coordinates and Angles

You may use this function to examine the surface shape at any location. The function may operate in one of two modes:

• Search Angle

  Function input is two principal planes. The first is cut with the selected surface to get a curve, and the curve is then cut with the second plane. The tangent angle of the curve (as measured towards one of the principal axes) at the intersection point is reported.

• Search Coord

  Function input is a principal plane and an angle towards a principal axis. The plane is cut with the selected surface to get a curve, and all points on the curve where the tangent angle equals the input are reported.
