Description Retrieves the parameters of a Linear Diffraction Grating assigned to a specified surface.
Syntax GetDiffractLinear n, angle, freq
Parameters n As Long Node number of the surface.
angle As Double Returns the orientation angle of the diffraction grating lines.
freq As Double Returns the frequency of the diffraction grating in inverse system units.
Remarks This subroutine retrieves the values of the Linear Diffraction Grating of a particular surface. If there is a problem, the subroutine sets an error and returns without modifying the parameters.
