Solving a Flat Face with UTD

To solve a model with the uniform theory of diffraction (UTD), you must activate UTD for each relevant flat face.

1. Select the face(s) in the 3D view or in the details tree that you want to solve with UTD.
2. In the details tree, from the right-click context menu, select Properties.
