Layer Management

This section describes the commands available to help assist you in managing your layers. All the layers created and used are standard AutoCAD layers and can be managed using standard AutoCAD commands. These commands are included for your convenience, but are not necessary. Everything you can do with these commands can be done with standard AutoCAD commands.

These command specifically change the On setting for the layers, toggling them between On and Off. The Freeze setting for the layers is not changed.

If you run these commands while in a paper space viewport, the VP Freeze setting will be changed also. This can be helpful when setting up drawings to display only the 2D or 3D layers in a specific viewport. You can use the Turn Double Line Layers On (and 3D Layers Off) command in the viewport that should display the 2D ductwork and the Turn 3D Layers on (and Double Line Layers Off) command in the viewport that should display the 3D ductwork. Then you can return to model space and use the Turn Double Line and 3D Layers On command to display both the 2D and 3D ductwork. You can continue to update both the 2D and 3D drafting while you design, but only have the desired view shown in each viewport.
