First of all, thank you for your reply. Currently, I am developing a CAM application on Windows using Qt to add Open Cascade, and I found a lot of what I was looking for in the Analysis situs APP. However, I don't know how to integrate analysis scenarios into my application. Or, how to use the profiling sdk, as with open cascading, I haven't found a way to download the profiling sdk. I am a newbie, thank you for your reply.
