[bug] Viewing a model

[bap]

I have been using FreeCAD for the last couple of days and have noticed this, it happens sporadically and I'm not exactly sure how to reproduce it. I experience graphical glitches when viewing my model, I use the "Blender" navigation style and it happens when I rotate. When I view the model with standard views its fine. Example:
Normal:

Now this is what happens when I rotate the model:




After a restart of FreeCAD I can't reproduce the bug, but this has happened a few times. I'll attach my file, though it may not help.

Thanks

Thanks, I'll do that next time it happens. It's not a very serious bug or anything, but I thought I'd make the thread anyway

Part of the object is behind the "Camera" / view frustum that's why it's cut off. Not really a bug you'd need to get the object back into the visible area. It can just happen any time with every object. I think last time I saw that was in a video from sliptonic ("Custom paths with python")

View/Standard Views/Fit All calls some boundary recalculation that fixes this cropping. No need to move anything.
