Remarks
This is not a general-purpose function: it only works properly for simple configurations.
For other configurations, it may return an incorrect result.
Some configurations for which the function might return a correct result are:
- A planar face that fully intersects another face in a single curve, when the other face is planar or cylindrical.
- A cylindrical face that fully intersects another face in a single curve, when the other face is planar.
