Just curious why would you change ltscle to 0, when you can just set pltscale to 1, in paperspace, and ltscale to 1 in paperspace, thereby making all linetypes regardless of how many viewports there are even if they are different scale factors and display properly.
I am a firm beliver if the drawing is set up properly, in working drawing ltscale is half of whatever dimscale. In plot drawing, the ltscale is 1. So you get your working drawing is lets say a ltscale of 24 and is refernced into the plot drawing, the ltscale should be 1 (24x1) If both are set to 24, the linetyppe becomes solid.
Mind you this is my opinion but setting it to 0, makes less sense than setting to .5. I meaan no disrespect, but celtscale is an older command that doesnt even really need ot come into play. Most subconsultants are using referenced drawings and I know that a standard for dimscale/ ltscale is best and when you open a set of plans Architects want to see linetyoes dispaly the same for all disciplines (at least ones I have been involved with). Workarounds are sometines a must just to get a project out the door. I have the problem where a workaround takes the place of a well practiced and established CAD standard. I appreciate any view, I am just trying to understand why a drafter would choose 0 or .5. Thanks
