Hi,
>> Are you saying that if I change my model space to .1
Not clear what you mean by "change model space to 1"
The settings MSLTSCALE has the meaning if the linetype scaling is controlled by the annotation scale (when modelspace is active)
PSLTSCALE (meant for viewports and layout) set to 1 means that the linetype scaling is automatically calculated in distance of paper, independent from the viewport scale. E.g. if your linetype is defined as 3 units line, 3 units space then this line will show itself (on layout and on plot) in the distance 3/3 in case the viewport scale is 1:1 or 2:1 or 1:2 or ... it does not matter.
When PSLTSCALE is set to 0 then the viewport scale controls the linetype scale, so a viewport 1:1 shows the line 3/3 whereas a viewport 1:2 shows the linetype scale as 1.5/1.5 (paper units).
