OpenCascade is an almost 30 year old C++ codebase that's known for being notoriously difficult to integrate.

The bigger issue is that OpenCascade is error tolerant to a fault, which allows it to import a lot more legacy geometries, but it also means that it silently exports a lot more bad geometries much more often than commercial kernels

So, there's a reason why commercial solutions don't really use OpenCascade over ACIS/Parasolid for authoring.
