Once and a while you run into a need to do an off the wall thing in Pro/E such as using Superscript and subscript text in a note. On a Pro Engineer drawing you can fill in parts of a note using parameters from the model such as the thickness of material used (can be any parameter) using text &thickness in a note will take the information from the Model parameter for thickness and insert it in your note, well I recently ran into a situation where the thickness was in a parameter and needed to be called out in a note but had a non-symmetrical Tolerance. the trick here is to fool ProE into showing a tolerance call out like shown in the image; by using @+ before text and @# after the text it raises the text up (superscript); in the same fashion that @- before and @# after lowers the text (subscript) so to get the text in the drawing with a +.040 the note would be @++ .040@# (notice two plus signs, first tells it super script and the second is the plus that is seen)
You will find it will take you a few trys at this to get it how you want the note on your drawing to look.

good luck and let us know how this tip works out for you.
