I downloaded 2012 SP1.0 and installed it. I then opened an existing file and created a sketch to do some cut to surface on the front plane. I wanted to cut a thin boarder, so I selected the entities for the offset enties command and and it placed the offset dimension on the origin and not on the original lines and the offset entities and would not let me click ok and select any other line or even the existing offset, the selection stayed in the dimension mode for the offset. I could go out of the sketch and do the cut, but I can not change anything in the sketch even after doing the cut, the selection is stuck on the dimension value of the sketch. Somehow I managed to delete the offset dimension and I could then select any part of the sketch I wanted. So I tried to do the sketch offset several more times in separate sketch's and was always the same issue, I could not select anything in the sketch after making a offset entities. Does anyone else have this issue? I did not have this problem in 2012 SP 0.
