| Summary | 0028279: Greater oscillations and higher degree of resulting B-Spline in cylinder-cylinder intersections in 7.1.0 | ||||
| Description | In 7.1.0 the surface-surface intersection algorithm produces resulting B-Spline curve which is somewhat greater distorted and has higher degree comparing to 7.0. See screenshots. This can be a consequence of the fix of 0023178. It is impossible to claim the result is worse than in 7.0.0 (i.e. a regression) as there can be other factors to be taken into account (greater number of sampling points in the marching algorithm, etc). So this is rather a FYI for the OCC team to double-check as needed. | ||||
| Steps To Reproduce | In both 7.0 and 7.1: intersect r s1 s2 and zoom the result | ||||
