|0002225||Sketcher||Bug||public||2015-08-22 00:17||2015-09-11 20:20|
|Target Version||Fixed in Version||0.16|
|Summary||0002225: Deleting link to external geometry crashes FreeCAD|
|Description||This isn't the usual work flow nonetheless FreeCAD should not crash.|
|Steps To Reproduce||- Create Sketch and add rectangle to it.|
- Pad it.
- Create Sketch001 on top face of Pad.
- Add 4 links to external geometry.
- Go back to Sketch and delete 2 edges of rectangle and add a new line to form a triangle.
It's normal and expected Sketch001 starts to misbehave as for example it can lose support... Trying to edit it adding additional links to external geometry is not possible. That probably is normal and expected behavior.
Selecting all 4 links to external geometry and pressing delete key will remove just 2 or 3 links to external geometry. Selecting remaining links to external geometry again and pressing delete key will crash FreeCAD.

|Sketcher: Bug fixes: inability to create links to external geometry
First bug: Inability to create links to external geometry as described here:
Second bug: FC crashes on changing the support after having imported external geometry as described here:
and solving this ticket:
Solution to first bug:
If for some reason a sketch ends up having a list of external geometries (property) that can not be recreated (rebuilt),
they remain latent, do not show the external elements in the elements widget or in the screen and prevent adding the
In cases where the saved file contains invalid external geometry links (which will give raise to a handled exception that would prevent external geometry creation),
this condition gets detected during restore and the invalid links are deleted before external geometry creation, so as to allow the rest of external links to be recreated.
Solution to second bug:
It is also related to invalid external links (the link was existing, but upon change on the support, it is possible that an external edge is no longer valid, reduction of edges in support).
This situation is detected upon entering into edit mode, and the invalid ones are deleted.
Note that there is still the possibility for the user to remap an invalid sketch BEFORE editing, if the remapping is successful, it may not be necessary to delete links (all depends on the
