Summary0000216: FreeCAD hangs on various operations
DescriptionFreeCAD hangs when creating the first item on a empty project.
Open FreeCAD. Click New. Click create a sphere. --> FreeCAD hangs on 99% CPU with steadily increasing memory until kill.
Revision 3729.

Has strong similarities with 3108976
Additional Informationcodeasylum said:
You're right. It was the "maximum deviation". Wouldn't it be nice to have
this value saved in the file too, so you can have various files with
various "maximum deviation" settings ?
TagsNo tags attached.

Ah I think I got it. In the preferences under Part design > Shape view what
is the value of the parameter "Maximum deviation depending on the model
bounding box". By default this value is set to 0.2% which is a good
trade-off. In case you have set to to something very small the problem is
that the tessellation algorithms generate a huge number of triangles which
causes the hanging.

n this context it was suggested to have a Deviation parameter per object so that the objects can have individual deflections. This is now implemented with 5027.
