The fix for the issue 0029421 creates three faces (as it is needed). However, the face f_3 is invalid in terms of BRepCheck. I have attached it in the file InvFace.bin (is opened by "binrestore" DRAW-command). Please note, that visually this face seems to be OK. So, maybe here BRepCheck algorithm works wrongly. It should be analyzed. Faulty status is returned by BRepCheck_Wire::Closed2d() method. It uses BRepTools_WireExplorer algorithm, which finds only one edge in the wire (in spite of wire's containing 4 edges). binrestore InvFace.bin ff explode ff w wexplo ff_1 ff puts [llength [directory WEDGE_*]] # 1 but must be 4 Please note, if we use BRepTools_WireExplorer only for 3D-space then it works correctly: binrestore InvFace.bin ff explode ff w wexplo ff_1 puts [llength [directory WEDGE_*]] # 4 ==> OK |

As result, the tests "bugs modalg_7 bug29807_b5a" and "bugs modalg_7 bug29807_b4a" changes self behavior. The number of entities has become as expected but checkshape result finds faulty entities. |

Please note that the degenerated edge is not trimmed by the intersection point with another edge. See NotTrimmedDE.PNG attached picture, where p-curve of InvFace.bin is shown. I think, it is a problem of Boolean operation in "bugs modalg_7 bug29807_b5a" and "bugs modalg_7 bug29807_b4a" test cases. |
