HiDoes anyone know how to retain the scale of a dotted line from model space to paperspace? ppaperspace lines are at a different scale to model space and when changing the paperspace linetype scale model space line type scale changes also? cheers, 

Hello, if you want to print from the model space or from the paper space the setings won't be the same.
 
For a print from the paper space :
The "lenght" of the dotted and center lines will change with the setings of :
LTSCALE ( try <1> ) , MSLTSCALE ( try <1> ) , PSLTSCALE ( try <1> ).
The "length" will also change if you choose different linetype ( try : centerline2 and hidden2 with LTSCALE = 1 ).
you will have also to have your viewports at the right scales ( and the size of your format OK ).
 
For a print from the model space, use the same but with LTSCALE x the scale of your drawing.
