Can I edit a sketch in the Spaceclaim after converting it to solid? If yes, could you please tell me how?

I am new to Spaceclaim and I have entered a sketch of a rectangle.  I want to change the size of the rectangle.  This is trivial in Solidworks or NX but I can't access the dimensions of the sketch after I first enter it.  I have created the rectangle but didn't hit the space bar to actually enter the dimensions.  How can I edit the dimensions?
