| Summary | 0004076: Freecad crashes when using Part Design Chamfer tool on a feature. | ||||
| Description | Freecad crashes when creating a Part Design Chamfer on a feature that has a subtractive path on it. I tried 4 times with smaller chamfer values but I am always receiving a segfault. | ||||
| Steps To Reproduce | Using the Part Design Workbench in a body full of features, then, trying to make a chamfer in some Edges makes Freecad crash immediately. For example, the edges that make Freecad break include: - Edge1 - Edge165 - Edge165 | ||||

@leoheck can you reproduce on 0.19_pre ? Also there is no linked discussion thread (as requested in the ticket posting guidelines (top of the page), please bring the community's attention to this by posting about it. |

Hi Kunda, sometimes I just don't know how to reproduce the issue. I mean, the Freecad file is the only thing I know/remember on how to reproduce it. I've been updating Freecad 0.19 every day, and the feeling is that is it is more robust now regarding the Chamfer tool. I also noted that we have a better way to remove chamfer features with the del key, which is really nice since sometimes the feature is missing or hidden somewhere. Now, my current problem is the Subtractive Polar Pattern. Sometimes when I have to update the base feature, this feature won't work properly anymore, and I don't know/have a way to fix it. My base feature is usually a revolution and the Subtractive Polar pattern usually can't make N copies of the object that subtract the main feature. I don't know why this happens but the effect is like it is not revolving in the z-axis (or it is shifted). Should I open a bug report for that? I really dont know how to reproduce. But I also want you to know these things. |

@leoheck : As a simple question : could you still reproduce this bug with latest 0.19 ? Regarding your new problem, please follow guidelines and open a new topic on the forum. |
|

This is crashing inside the OpenCASCADE code. I checked with latest binaries of OpenCASCADE TKFilletd.dll and the issue is not reproducible. I think it is fixed in the latest version of OpenCASCADE. I am new to FreeCAD development so it will be really great to know what action needs to be taken on this issue given the above observation. |
|
|
@rajendrasp79 : it may depend on OCC build flags. See 0003436:0012736 |
|
|
@leoheck can you reproduce this per 0004076:0013932 |

This should be resolved by the fix in 0004543, but the download of the test file from the OP is failing for me, so I cannot test. If there is a forums post that has that attachment, can you link it here? |

@chennes has created a downstream patch that fixes the crash. It is slowly being integrated in to downstream packages (ATM libpack is the only one but more will follow). This issue is therefore being marked as resolved. It will be closed one all packages are patched or when (if) upstream merges. |
|
|
This patch has been merged into OpenCASCADE 7.6, and the patch for earlier OCCT versions has been incorporated into all packages of FreeCAD 0.19.3 that I am aware of. |
