Is it possible to make wall lines dashed in plan view?

I want to make a wall style such that it looks dashed in plan view. Is this possible? When I set the linetype to dashed it there is a thin line underneath that takes away from the dashed effect, I would like to remove it from the display but don’t know how.

I think your display mode is set to shaded. In display options you can reduce the edge thickness (pixels) to 0.

If you change the display mode to hidden, you don’t see them at all.

Excellent, thank you Mark, I can’t believe I didn’t think of that
