editing an existing sketch. vs. starting a new one

coming from a One Space Designer & Solidworks background, i'm trying to
"go back into" an existing sketch, to edit it.

but it (pro-e wildfire) "won't let me" -- i can't find out how to get
into the original drawing mode that i was in when i created the sketch.

i can't imagine that pro-e forces users to get the sketch (from which a
geometry is created) right, first time every time.

so, in pro-e, how do i modify an existing sketch ? i don't mean go in
and change dimensions - i mean "start drawing new stuff".

thanks.

 

That's a lot of pecking to ask;

"How do I Edit (Definition) a sketch?"

8~) Ok, so I'm a wise a$$.

WF1 or 2, interal or external (to the the feature)?
