If SetNonDestructive is set to false it does not fail. |
(0062079) msv (developer) 2016-12-23 18:11 |
I have obtained 3 solids (see the picture) without setting any flags. What is wrong in your case? |
(0062080) Istvan Csanady (developer) 2016-12-23 18:12 |
If I set the SetNonDestructive flag to true, it returns an empty compound. |
(0062081) Istvan Csanady (developer) 2016-12-23 18:14 |
BOPAlgo_MakerVolume volumeMaker; volumeMaker.SetArguments(facesList); volumeMaker.SetRunParallel(true); volumeMaker.SetNonDestructive(true); volumeMaker.SetAvoidInternalShapes(false); |
(0062082) msv (developer) 2016-12-23 18:21 |
With setting these options, I obtain the same 3 solids. However checkshape complains about IntersectingWires.Draw[111]> checksh r On Shape faulty_1 : BRepCheck_InvalidPolygonOnTriangulation On Shape faulty_2 : BRepCheck_InvalidPolygonOnTriangulation On Shape faulty_3 : BRepCheck_IntersectingWires Faulty shapes in variables faulty_1 to faulty_3 With non-destructive=false, only 2 first faulties occur. |
(0062083) Istvan Csanady (developer) 2016-12-23 18:22 |
Interesting, I tried it with and without fuzzy, and got the same results. |
(0062084) msv (developer) 2016-12-23 18:24 |
I test on Windows compiled with VC12 in release mode. |
(0062085) Istvan Csanady (developer) 2016-12-23 18:25 |
If I copy the shape before performing the operation, it will work fine. |
(0062272) Istvan Csanady (developer) 2016-12-28 19:16 |
I have the same issue with the new attached file, but in this case the result does not depend on non-destructive mode or on fuzzy, it always fails (debug and release mode). |
(0062331) msv (developer) 2016-12-29 18:07 |
The case with splines.brep needs additional investigation. |
(0062334) Istvan Csanady (developer) 2016-12-29 19:12 |
Would more test data be useful? I find that in similar cases VolumeMaker is not very robust, and I can easily create similar cases where it fails. |
(0062336) Istvan Csanady (developer) 2016-12-29 20:43 |
Exception.brep fails because one of the face-face intersections throws an exception. |
(0062347) Istvan Csanady (developer) 2016-12-30 01:26 |
Applying MakeVolume on broken_solids.brep leads to invalid shapes. |
(0062348) Istvan Csanady (developer) 2016-12-30 01:38 |
I have successfully reproduced the issue with similar geometries that I converted to NURBS geometry. This means that the problem can be related to periodic and/or closed surfaces. |
(0062383) Istvan Csanady (developer) 2017-01-01 17:43 |
Another similar issue: only_one_solid.brep generates a only one solid, instead of two. |
(0069985) mkv (tester) 2017-08-28 15:14 |
Problem described in issue is reproduced on current state of OCCT. |
