Hello community, I have a CAD object created from a STEP file loaded into the lens editor. When I run a raytrace and save rays, I see a correct raytrace. When I try to use the X_HITFACE(n,b) filter to isolate and visualize specific rays it does not work. I set up the filter to show only rays that pass directly thru the faces that define the lens region. The filter returns no rays passing thru the lens face even though I can clearly see rays passing and refracting at the lens face. I have correctly identified the lens faces using the CAD tab under the object of interest. Does the filter not work on CAD objects.  

I am using Ansys OpticStudio 2025 R2.01
