Hi Lucy,

Thanks for your question here!

Did you try to run the full Standalone example, or just tried to run the above code snippet from a modified file?

Running the complete Standalone Application example #14 - Tolerancing, worked fine for me, and in this case I got 24 tolerance operands using the Double Gauss 28 degree field.zmx sample file from the \Documents\Zemax\Samples\Sequential\Objectives folder. Please find the resulting system attached as a .ZAR archive file.

I also ran a similar code from the Interactive Extension, while I had different files open in OpticStudio. In this case the code worked fine too, and I only got 2 operands when I had an empty new file open in OpticStudio, like this:

Is it possible that the file loading was not correct in your case, and you tried to set up the tolerance wizard on such a simple file?

Please find my .m MatLab files attached, and try to run these on your end.

I hope this helps, but if not or if you have any further questions, please let us know and we will be happy to help!

Best,

Csilla
