Hi Niki,

thank you for coming back to me. The parasolid library box is ticked. 

I just tested unticking the box, and on exporting I get the error message "surface 12 failed to export". This is the standard surface just in front of the diffraction grating, making a tilted prism surface as the element is a grism.

 

 

On the plus side, the remaining surfaces are at the correct positions now. So I get the grating, but not the two tilted prisms around it. It is the 2nd element from the right now, the yellowish rectangle. 

So chosing the parasolid library causes a mess up of tilted surfaces. Deselecting the library causes wedged surfaces not to export.
