ok so i just measured the true length of one piece of dashed line at 1 linsecale and it is about 6 (meters i think....don't know why autocad doesnt show the measurement units just to be doubly sure!). Now, I want the dashed line to be lets say about 0.75 cm (or 0.0075 m) on paper. However my paperspace scale is 7500. That means the dash gets scaled down to 6m/7500 =0.0008m. So if i am using psltscale, ltscale and msltscale all set to 1, then my annotation scale needs to be:
0.0075/0.0008 = about 10
But that still shows a solid line.
Interestingly, switching psltscale to 0, finally does show dashed line in paperspace...This is so confusing
Another thing i noticed was that whilst when you have your drawing in meter units, the scale is typically like 1:1 is actually 1:0.001 because the paper units are in mm as I have understood so far e.g. from this:
Resetting the scales list leads to wrong scale definitions that are corrected after reopening the DW...
THis is how it was when i first started working on this drawing but along the way, it seemed like my paperspace started thinking in terms of meter units also. So then 1:1 was really 1:1. Don;t know if this is normal or what i might have done to cause this. I dont know if this is causing the dashed line issue. Such a simple thing just made to complicated 😞
