Summary0027906: Intersection algorithm between trimmed cylinders having common base returns empty result
DescriptionSee Steps To Reproduce.

Indeed, the cylinders have common base. I.e. the circle is expected as intersection result. However, it is empty.

This bug is reproduced even on OCCT 6.7.0.

The behavior of the intersection algorithm is as expected. Two trimmed cylindrical surfaces built on the same cylinder must not have intersection.

Dear bugmaster, please close this bug.
