I am doing a large trace over of an existing hospital I am currently working on. I have the plan @ the correct size to start. I have already done a trace over of part of the plan and was asked to go back and do the entire plan. It took a while to get the partial correct, and now I am trying to trace over the entire pdf file. In order to get the pdf to align with the angle of my already drawn plan, I need to be able to rotate the pdf "precisely" but can't seem to find anything in the help. I did try turning off the angle snaps in the edit dialogue, but when I grab the rotate handle I can't get it to rotate the pdf at small precise degrees until I match perfectly. Any suggestions aside from starting over?
