Hi Paula,

I don’t believe there is a way of changing between an individual config and using all the configurations.  However, this option appears to be saved in the CFG file for the analysis.  So you can setup your Huygens PSF window with the different CFG files (one for Current and one for All) and then use win.LoadFrom() to switch between a single configuration or all the configurations.   

@David.Nguyen has a really good writeup for a step-by-step guide in the following answer: 

How to change 3D layout properties via ZOSAPI | Zemax Community

Thank you Michael for your quick response. I’ll try it right away. Thanks!

However, this option appears to be saved in the CFG file for the analysis.  So you can setup your Huygens PSF window with the different CFG files (one for Current and one for All) and then use win.LoadFrom() to switch between a single configuration or all the configurations. 

Just out of interest, would it be possible to then do the following using the API:

1. Create a new analysis
2. Use GetSettings().LoadFrom(file.cfg) to switch to all configurations
3. Adjust other settings using GetSettings() as one would normally do using the API
4. Run the analysis

That way, this flow can be kind of implemented without having a different configuration file for every possible (or desired) combination of settings. 

Of course, this is only relevant if you want to run all the configurations at once, as requested in this post. Else, you could simply switch configurations and run the tests.
