Thanks for all the replies. I was looking for a programme for the very reason N_O_Body stated, so much easier to alter than any work on graph paper. My problem is, that I don't really like remodelling whole city areas once they're built up, on the other hand that's how it's done in reality...I'll probably just have to gest used to do that, after all, my planning rarely works out in the game (damn commuters).
