Rolling your own Brep isn’t for the faint of heard. There is quite a bit of work in putting together the most basic shapes, let alone a patched face with a bunch of holes.
The famous Brep data structure:
Here are a couple of samples, in C#, to chew on:
Now if you really want to trim, not split, then it is possible to create a disjoint Brep, with a bunch of extruded surfaces, and then use Brep.Trim. I can work up a sample if you want…
