Summary

0027906: Intersection algorithm between trimmed cylinders having common base returns empty result

Description

See 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.

Steps To Reproduce

cylinder cy 100
trimv s1 cy 0 200
trimv s2 cy 200 500
don s1 s2
ax
fit
intersect result s1 s2
# Empty result

mkface f1 s1
mkface f2 s2
bopcurves f1 f2 -2d
# has no 3d curves
# has no 3d points

Notes
(0058189) msv (developer) 2016-09-27 11:41	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.
