Perhaps this awful program will propose one day the list of external relations, making some flip of the sketch impossible (and as SW ignores that the topology of a plane and of a Moebius strip aren't the same ....), generating some parent-child relations, making obstruction to some move in the feature tree ...
Perhaps in a 2015 or 2016 version, this awful program will propose using local frames, global frames, and using of transformation matrix.
Those basic features are surely too much confortable, for any guy having some basic maths in mind.
Assemblies of 2000 or 3000 components... LOL
Let try a cube with 8 cubic parts : if I hide one brick, all disappear in the same bunch LOL
Even with that, this awful program is unable to have some decent behaviour.
