I'm looking for some insight on a issue that is causing the office a lot of headaches!

Here's the scenario:

In the working drawing, model space is set to 1:1 annotation scale. (PSLTS is 1, MSLTS is 1, LTS is 1)

In a separate drawing (used for plot sheets), we place the working drawing in as an XREF (PSLTS is 1, MSLTS is 1, LTS is 1)

When scaling the viewport (XRED) in paper space, say 1:20 scale, the line work, particularly "batting" line type is all out of scale. To fix this we go back to the working drawing and change the annotation to match the desired plot scale, REGEN and then it works. However, some drawings are going to be plotted at 2 or more scales, so it's becoming very time consuming.

Is it possible to draw everything at 1:1, but in plot files set it to any scale in paper space and have all the line types appear as they do in the working drawing.

I look forward to learning if this is possible!
