Still crashes here with the OCE from tanderson, OCE patches over OCC 6.9.1 OS: Ubuntu 12.04.5 LTS Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.16.6523 (Git) Build type: Release Branch: master Hash: ecd6517cb00fcf05edd41a38b3ce1fa8b16ec3ad Python version: 2.7.3 Qt version: 4.8.2 Coin version: 3.1.3 OCC version: 6.9.1.oce-0.18-dev |

@joostn do you mind re-uploading the attachment? It didn't survive are previous tracker backup restore. |
|
|
I hope this is the file (it has the same name). |
|
|
@normandc do you mind weighing in ? |
|
|
With occ7.2 it still crashes and shows the identical stack trace. |
|
|
@chrisb would you please test to see if issue is still present. Thanks! |
|

Adding to 0.19 roadmap so that bug gets attention |
|
|
I have reported the bug upstream and provided a possible patch to avoid the segfault: https://tracker.dev.opencascade.org/view.php?id=31601 @Kunda1 For your administration ;) |

Can we hope this 4 years bug to be solve in a near future ? I can see proposed patch but always testing newer version never solve the problem... This bug really kills Freecad experience and adoption because it prevents the realization of even simple shells that are the most common operation for boxes and enclose cases... So we have no workaround than using another 3D CAD... Really too bad ! |

I am coming back on this issue with the following example showing a weird behavior that can lead to better understand the bug. In the following example, removing the face without fillet and trying to create a thickness of 1mm inward leads to the famous bug... But if first of all I create a thickness of 0mm inward I obtain a new solid that then enables to create a thickness of 1mm inward without leading to the bug. So the bug could be on freecad side ? |
|
|
When I do the same steps (thickness of 0 mm inward), the body is also rotating 90 degrees on the x axis As I understand it, problems arise when there are chamfer (or fillets) in the part. When a wall is created inward, the chamfer also scales, and at some point it seems to invert and create self-intersections. I more or less learned how to bypass this problem by adding fillets to the chamfers or chamfers to the fillets, but this is not the solution to the problem, because it takes a long time to guess the right values. |
|
|
Here, I managed to make desired (2,4 mm) inward thickness and chamfers, but I have to add Fillet001 to apply Thickness |
