Crash on sketch loading about freecad

[RiccaDS]

I deleted parts from the file to make it simpler and reproduces the problem anyway. This way you shouldn't need to install the fasteners WB either
crash1.zip

I downloaded the simplified file and can reproduce the crash :
<Exception> TopoShapeExpansion.cpp(2066): Shape index 71 out of bound 19

updateGeometryColor was changed by me during the sketch colors PR (construction lines and point colors both). However I do not think they could cause the crash. From the error I'm seing, the likely culprit is the current TNP work. @bgbsww @CalligaroV

As far as I can tell, the code that ensures that we correctly handle missing external references applies not just during a file load, but during each close and open of a sketch. So this patch appears to handle both the crash, and the generation of an invalid sketch. Thanks for the extra detail, RiccaDS.

Sketch won't open on my side, no crash though.

EDIT:
I noticed it crashes if you zoom out in the view to a big extent. This should be reproducible.

Yeah, it doesn't open (but shows some Sketcher constraints and elements in the Tasks tab) and doesn't crash on Windows in 0.22 weekly. Just throws a bunch of errors:

FreeCAD does not crash when opening the sketch, but crashes when closing. SketcherGui::EditModeGeometryCoinManager::updateGeometryColor again causes the crash.

FreeCAD reports when opening:

does it work with the stable 0.21.2 version?
Might it be related to the materials update?

Tested this now in 0.21.2 and the sketch loads normally and apparently without problems

I'll start looking into this, but I'm also getting this on opening:
15:28:14 pyException: Traceback (most recent call last): File "C:\Users\dcarter\Documents\Projects\freecad-build\bin\Lib\site-packages\shiboken2\files.dir\shibokensupport\__feature__.py", line 142, in _import return original_import(name, *args, **kwargs) <class 'ModuleNotFoundError'>: No module named 'FastenersCmd' 15:28:14 pyException: Traceback (most recent call last): File "C:\Users\dcarter\Documents\Projects\freecad-build\bin\Lib\site-packages\shiboken2\files.dir\shibokensupport\__feature__.py", line 142, in _import return original_import(name, *args, **kwargs) <class 'ModuleNotFoundError'>: No module named 'FastenersCmd'

That'll need to be fixed before assuming the error is anywhere else. Does this model use the Fasteners workbench or other external workbench?

Sorry. Just read the configuration from the original post. I'll install fasteners and try again

there is a fasteners threaded rod in the group "costruzione" but this I don't think is related to the problem as that part is hidden. Just a missing module for you.
As a note, Hole007 is threaded(not displayed) but uses the normal threading option, not the fasteners workbench. However this threading is adjacent to the Groove whose sketch gives the problem. Don't know if this might be related.
Thanks for looking

Reproducible here. Issue appears to be in SketchObject::restoreFinished which calls SketchObject::validateExternalLinks which ends up down at the error. Seems to be a case of missing hasher code in TNP work. More investigation to follow.

[bgbsww]

No, that error is as a result of the file that clearly has a bad external reference in the sketch object. Issue is how it was created, not how it is read back in.

Should not crash tough :D

[bgbsww]

Agreed on the crash - I'm working on that. Curious if you have any idea how we came to have a reference to Edge71 and Edge31 in an object with only 19 Edges? I've tried a lot of things and to create a test to recreate that failure, and I can't so far.

@bgbsww ehm, no not really, I lost track of what I did. I've been using FreeCAD for quite some time now but I wouldn't consider myself expert in best practices and such. I am aware of the topological naming problem when sketching on the face of a same part but I admit not following the best practice to avoid that. Maybe I sketched, referenced and then modified the base part which resulted in corrupted references. Or maybe the thread modeling has something to do in this. As you can see from the picture, the hole is actually threaded, if I set "Model Thread" to True, I can see edges that have very high numbers (ex Edge67 in pic)

this seems to be Edge71 in fact. Maybe I shouldn't have referenced to that edge if disabling "model thread" later ? :D
Indeed I found out that opening the sketch does not crash anymore if the "model thread" is set to True. I disabled it for machining purposes in the CAM module.

[bgbsww]

Thanks! I'll hunt that now. I do have a working fix for the crash - when the exception is thrown, we leave things in a messy state - I can fix that. I just don't want to hide the base cause if I can find it too.

[RiccaDS]

Sure, I made a few tests and can confirm the issue on other similar and simpler models.
1- Make a threaded hole with "model thread" to True
2- Sketch and reference to one of the edges of the thread
3- Set "model thread" to false
4- Double click on the sketch and crash happens

Thank you for looking into that.

[RiccaDS]

As far as I can tell, the code that ensures that we correctly handle missing external references applies not just during a file load, but during each close and open of a sketch. So this patch appears to handle both the crash, and the generation of an invalid sketch. Thanks for the extra detail, RiccaDS.

Just checked the weekly build, works great , thank you very much! ideally it would be perfect if the external reference was maintained even when the thread model gets disabled. As I mentioned it's not uncommon in machining setups to be in need of the model with the thread and the one without. So it's pretty frequent to enable/disable the thread model. Correcting this probably however is quite some good work as, in my understanding of how FC manages threaded holes, the thread model geometries are created/deleted each time one enables/disables the thread model, so it would be necessary to implement a "layer" with the thread model, that can be hidden/shown, which I believe can get really not straightforward :D
