Civil 3D Linetypes Look Different in Model Space vs Viewports
Issue: Linetypes display correctly in Model Space but appear continuous or wrong inside Layout viewports.
Cause: Linetype scaling (MSLTSCALE, PSLTSCALE, LTSCALE) is mismatched between Model Space and Paper Space.
Solution:
-
Set MSLTSCALE = 1 so linetypes respect annotation scaling in Model Space.
-
Set PSLTSCALE = 1 so linetypes scale properly in viewports.
-
Use a consistent LTSCALE (often 1 or 0.5) across the drawing.
-
Regenerate (REGENALL) and resave — this fixes most viewport display glitches.
