When placing a sketch in 2012 you have the option to input a numerical value to define the size of your sketch. There is an option to "add dimension" when you do this. By default it is turned off, so for evey type of sketch in each new session I have to turn this on. I]ve looked thru my system and document settings for the default option to have this on but can't find it. Is this option avalible and where can I find it?
