After integration the fix for issue #26132, test case bugs modalg_1 buc60462_2 changed its behavior. Now it throws an exception. The main reason of the exception is creation not same-ranged edge by Boolean operation. The algorithm cannot find interference between the seam-edge of one face and the edge of another face. Try the following script for clarifying: Draw[]> restore [locate_data_file buc60462c.brep] a Draw[]> restore [locate_data_file buc60462d.brep] b Draw[]> explode a f Draw[]> explode b e Draw[]> ax Draw[]> donly a_9 b_46 Draw[]> toler b_46 #0.0044857456383894396 Draw[]> distmini dd a_9 b_46 #0.00167963807727123 ==> b_46 "intersects" the seam of a_9 Draw[]> bclearobj Draw[]> bcleartool Draw[]> baddobj a Draw[]> baddtool b Draw[]> bfillds Draw[]> bopds Draw[]> bopindex b_46 # Index: 158 Draw[]> bopsp #Edge 158: z158_158 ==> b_46 were not split. Later, 2D-curve (on a_9 face) with range [0, 0.0336066450154111] will be added in z158. At that, 3D-curve of z158 already has range [0, 1]. As result, z158 will become invalid. In short, edge b_46 is coincided with face a_9. Therefore, in IntTools_EdgeFace::Perform() method, full range of b_46 edge is used as common-block between b_46 and a_9 (range is [0, 1]). And edge b_46 is not split. Before fix (on the current MASTER) b_46 edge was split by the point found by IntTools_BeanFaceIntersector and result seamed to be valid. The good idea of the fix is that the reason of failing Edge-Edge intersection (between b_46 and seam of a_9) algorithm must be clarified. If edge-edge intersection find intersection point then myRange in IntTools_EdgeFace::Perform() method will contain correct range for checking coincidence. |
|
In the current version there is no exception. The test buc60462_1 is OK. The test buc60462_2 reports error condition that the result of fuse contains 2 solids instead of 1. This test case always generated bad result. So, the current state of the test result cannot be considered as regression. Removing word 'regression' from the title. |

I propose to close this bug. |
