A trick I learned is to set my annotative scale to the scale I will use to plot with. Then set my msltscale to 1. This way I get to see the lines as they actually are in both spaces. Have had to create custom line types to get some lines to look how I want.
You have to enable linetype generation.
Select the polyline and in the properties palette, change the linetype generation to "enabled"
Or do a polyline edit, look at the command line, and enter Ltype gen.
Your polyline vertices are so close together that the hidden lineype shows as a continuous line.
I'm also not sure how you creted the polylines, are you starting with a metric template and using imperial linetypes?
I had a much better result copying your polyline and pasting it into my imperial template.
Is there a way to set the Ltype gen universally? I’m actually pulling the lines from an engineering software program. For this drawing I wasn’t paying attention and pulled the dxf into an imperial template though it is in meters. Thanks for your help, at least I can get dashed lines now, once I figure out how to set the ltype gen setting.
Check the PLINEGEN system variable.
0 - generates polylines to start to end with a dash at each vertex
1 - generates linetypes in a continuous pattern around the vertices of a polyline
