I recommend that PTC should implement this option very early.
If you create in a sheetmetal Part a coordinate system and you forget to unselect the "Follow surface", then this will automatically produce a Geom Check if you move that on the top of the modeltree.(see pics).
Also very annoying is, that this "Follow Surface" option now can't be eliminated (with Edit Definition) Only if you move back the new csys.
Please PTC implement a config.pro option to uncheck this by default!
