I have created a custom object based on the sample of the HalfCylinder.DLL object. So far, this works. I would like to return a value directly to the non-sequential component editor. E.g. for the half cylinder, add a field volume and return the current volume. This way during optimization, I can control the volume of the cylinder without using extra scripts to use the volume. I tried to use an extra field, and then attribute a value inside the code:

in the given half cylinder, in line 64 (just before the switch(code)):

data[104] = volume;

but the volume field in zemax’ non-sequential component editor is not updated.

I hope to get along the idea of I want to do. For the volume, I could use a script in zemax, but imagine it is value that I calculate in cpp anyway, it would be more efficient to reuse this. Is this possible?
