I just created a button for printing. It's a 1 button for all your plots kind of thing. Everything in the plot command is the same except for the plot scale. My first thought was to prompt the user to enter the scale like 1=48 type of thing. But, then I had an idea. Use DIESEL. Where it would prompt for the scale in the MACRO I added..
this will enter the ratio of plotted units to drawing units. No prompting, no hassel.
