I have to look then, because personally, I usually import my cartridge into the paper space, I make Fmult to visualize the object space and I don't use layout 1.
I'll get back to you a little later to tell you what happens.
thank you for your answer;; But if you place your cartridge in the paper space, it's because you're in layout1 (or presentation1)
So yes, you open multiple windows, no worries. But the question is always the same to settle if for example you want 1:50 in window1 and 1:2 in window2... The ZoomScale does indeed create a zoom but without really any real link to the said windows.
If you select the view (or window in DraftSight) on the properties on the left, you have a drop-down menu and a text box where you can specify a scale...
If nothing is selected, it is the sheet
I took a screenshot to illustrate what I am saying.
