Sometimes when changing the definition of a sketch plane its coordinate system goes bananas, often it just mirrors/flips. This makes parameterized modeling close to useless since I have to spend time repairing large chunks of the model and sometimes delete the sketch and start over.
I ask if it probable that I would want to flip all geometry that the sketch defines even if the planes were parallel? I think not. It would be really nice to have at least one of these two options:
* A small checkbox for horizontal flip and one for vertical flip. The green/fixed lines could be re-associated with automatically activated "manage lost projections"-dialogue box if applicable.
* Orient sketch X (& Y) axis with (line/edge) Or project from part origin.
