Hi Giorgio,

Thanks for your question here!

Unfortunately, currently there is no way to export the diagram in order to get all the coordinates.

Currently, as a workaround, you could achieve this by running a macro looping over an array of single ray traces and saving the coordinates at the desired surface. You will need the following keyords and numeric functions: RAYTRACE, RAYX(n), RAYY(n), RAYZ(n) for the coordinates and RAYL(n), RAYM(n), and RAYN(n) for the direction cosines following the surface.

You may find more info about this in the Help file under:

The Programming Tab > About the ZPL > KEYWORDS (about the zpl) > RAYTRACE

This idea to give acces to the coordinates from the Spot Diagram or Footprint Diagram has been brought up before our customers and there's a feature request for it. I have gone ahead and voted for this feature request in our internal system on your behalf. Please keep in mind that feature requests are weighed based on impact, difficulty to implement, and the number of users who request it. A request is not a guarantee that the feature will be added to a future release. However, these feature requests are very important to us and shape the future of OpticStudio, so we appreciate your input!

Thanks, 

Csilla
