Turn 3D Layers On (and 2D Layers Off)

The Turn 3D Layers On (and 2D Layers Off) command turns the 3D pipe layers on and the 2D pipe layers off.

The 2D and 3D pipes 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 pipes while in an isometric or other 3D view.

To turn the 3D pipe layers on and the 2D pipe layers off, go to
Ribbon: DM Plumbing→3D-BIM→  Turn 3D Layers On (and 2D Layers Off)
Pulldown Menu: DM Plumbing→Layer Management→Turn 3D Layers On (and 2D Layers Off)

The 3D pipe 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 2D pipe 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 2D layers will be changed to Frozen.
