Turn 3D Layers On (and Double Line Layers Off)

The Turn 3D Layers On (and Double Line Layers Off) command turns the double line ductwork layers off and turns the 3D ductwork layers on.

The double line and 3D ductwork are drawn slightly different. Viewing both of them at the same time can make it difficult to see what is drawn. Turning one on and the other off makes it easier to see the design.

Use this command to view the ductwork while in an isometric or other 3D view.

To turn the 3D layers on and the double line ductwork layers off, go to
Ribbon: DM HVAC→Layers→  Turn 3D Layers On (and Double Line Layers Off)
Pulldown Menu: DM HVAC→Layer Management→Turn 3D Layers On (and Double Line Layers Off)

The 3D ductwork layers will be turned on and visible on the drawing.

If this command is run while in a paper space viewport, the VP Freeze setting for the 3D layers will be changed to Thawed.

The double line ductwork layers will be turned off and not visible on the drawing.

If this command is run while in a paper space viewport, the VP Freeze setting for the double line layers will be changed to Frozen.
