Turn Duct Centerlines Off

The Turn Duct Centerlines Off command turns duct centerline layers off. These layers are typically on a non-plotting layer that will not appear on your printed drawings. It is often helpful during the design to turn these centerlines on and off to see what your final drawing will look like.

To turn the centerlines off, go to
Ribbon: DM HVAC→Layers→  Turn Duct Centerlines Off
Pulldown Menu: DM HVAC→Layer Management→Turn Duct Centerlines Off

The centerline layers will be turned off and will not be visible on the drawing.
