oiep -> for Options/sketch/set driven by default, it's if the sketch is overstressed and then it's as if all the sketches are overstressed all the time.
Coyote-> Yes, even if you're doing a new piece. In fact, we make the sketch and we dimension it: no controlled dimensions. We register and close. We reopen the room and they are put on the pilot! They appear grayed out when you are drawing.
You can uncheck the "piloted" option from the rating. But we have to do it one by one. That is to say, after modeling a part with 50 dimensions for all the sketches, you then have to reopen each sketch and modify the dimensions one after the other to put them back in control and use them as such in the MEP
The problem is that the teacher who has this problem makes his students rate with Objects of the Model. And he ends up with piloted dimensions in his MEP. So he has to reopen all his parts to remove the option on a side driven side by side option.
It may be a bug in this SW2013 Education (SP2) release.
