| Summary | 0033482: Modeling Algorithms - Bad result with BRepAlgoAPI_Common | ||||
| Description | Hi ! BRepAlgoAPI_Common can give no result although there is clearly a big common part between 2 shapes (see attached picture) | ||||
| Steps To Reproduce | You can use Tool and Argument joined in "NotDetected.zip" | ||||
| Additional information and documentation updates | A very slight transformation in Z of one shape give the right result. You can check with Argument and Tool in "Detected.zip". It looks like the result is bad when the shapes are perfectly aligned in Z (see picture). It seems that "curves" value in myDS can be wrong. Behaviour between good case and bad case is different in getBoundPaves (hierarchy is PutBoundPaveOnCurve / MakeBlocks / ... / IntersectShapes) : vertex and point compared are sometimes too different. | ||||

Dear @j.bourgoin. current problem can be solved by decreasing the tolerance for boolean operation (to 0.00001). If it is not your case, we can continue investigate this problem. |
