PMRO6
Your approach is exactly the one I use.
11ECHO-
Its really much simpler than it appears:
Start here-
1. run the plot command without a dialog box:
-plot
WRITE DOWN EVERY command prompt, and your CORRECT response. This'll take a bit of experimenting, but the result is worth it. Along the way, you'll get ONE plot that's useable and correct. (I usually try to plot-extents to fit, but that's a different topic...)
1 plot down, a couple more to go...
2. Open up NOTEPAD and type in what you think is a CORRECT script line, based on what you wrote down as you de-bugged the command-line approach to running the plot, earlier. You would then paste this script line back to the ACAD command prompt. BE careful- as careful as you can: learn about scripting in the process. Paste the line into ACAD, at the command prompt. Debug it until it runs right. Use PMR06's post as the rosetta-atone clue you'll need to succeeed.
Eventually you'll get a good run.
2 down- you're approaching success, and have 2 good plots to use, in the process. YOUR LEARNING TIME IS THUS BILLABLE !
3. Open the 3rd drawing. Run the script as-is. If you get a good run right away, SUCCESS ! Repeat this step with another dwg. Repeat as often as you'd like, until you decide to
learn how to take the script you wrote in notepad, and embed it into a button. I created an "auto-plot" button right next to my plot button, and whenever I want a plot-extents-to-fit model-space auto-plot, I have it. I then created an auto-plot in paperspaace (tab) button, and now I'm covered. I now pay some attention to various standard plot settings as I vary them and set them to keep, in the regular plot dialog, so that those variations work too, at subsequent auto-plots. I Like color-based ctb color/line-weight control. Personal preference.
The point- PMR06's approach is a good one, and mastering it will have some peripheral benefits that you might not have originally expected. Another Side Benefit- as you become familiar with buttons, internal and external scripting, and move into LISP and VBA, you'll see that the real requirement for becomeing a sharper knife in that drawer is some patience, a little commitment to mastering your craft, and some creativity. Yes we make drawings for a living, but its a heck of a way to earn a living !
Good luck-
