Viewport Layer
Keyboard: VPLAYER
Alias: VL
Controls properties and visibility of layers in layout viewports. Using this command, you can make layers that display in one or more layout viewports invisible in other layout viewports within the same drawing. You can freeze or thaw layers in layout viewports that you have already created, and you can change the default setting for all new layout viewports you create. Before running the command from a Layout tab, double-click inside a layout viewport to make it active. If running the command from the Model tab, limited options are available.
You can also change the properties of layers in layout viewports using Explore Layers.
NOTE You can control layer visibility only for layout viewports in your active drawing. You cannot change the visibility of layers for layout viewports in externally referenced drawings.
