Good day, everyone

I've recently come across Xarial Xcad and started exploring how to create custom add-ins. I've been learning bit by bit and have managed to grasp some of the basics. That said, I find the tutorial somewhat scattered—I can follow the steps, but I don't fully understand the purpose behind certain parts of the code. I assume this might be due to proprietary reasons, and I just want to clarify that I'm not complaining.

So far, I’ve successfully set up a "Hello World!" message to appear in SolidWorks at startup. Now, I’d like to take it a step further by incorporating one of the examples from GitHub—specifically, the parametric box. From there, I plan to build on it and explore more features.

Can someone please help me how to do this. Thanks.

Below is the link to the GitHub repository I’m referring to:
