This is a User Defined Object DLL, which allows users defining a polygon plate with 8 x and y points data and thickness. The polygon is linked in order of the points defined in parameters. If a point is set with (0,0), it’s ignored. To consider a point at (0,0), users need to use a smaller but non-zero number, like 1e-8 to replace the 0. All the value of x, y will be multiplied by the parameter “Scale”. If “Scale” is zero, then it’s converted to 1.0 internally. If the parameter “Z Center mode” is 0, then the local origin (0,0,0) is located on Face 1. If “Z Center mode” = 1, the local origin is shifted in z direction by -Thickness/2 so it’s centered between Face 1 and Face 2. If “Z Center mode” = 2, the shift is -Thickness so the local coordinate origin is at face 2. If “Diffract back Face” is non-zero, the grating is on Face 2 instead of Face 1.
