Freezing and Thawing Layers in AutoCAD

You can freeze layers to speed up ZOOM, PAN, and VPOINT, improve object selection performance, and reduce regeneration time for complex drawings. AutoCAD does not display, plot, or regenerate objects on frozen layers. Freeze layers that you want to be invisible for long periods. When you “thaw” a frozen layer, AutoCAD regenerates the drawing and displays the objects on that layer.

To freeze or thaw a layer

  1. From the Format menu, choose Layer.
  2. In the Layer Properties Manager, select the layers you want to freeze or thaw.
  3. Click the Freeze in All Viewports icon to turn it on or off (on to freeze a layer and off to thaw a layer).

Command line LAYER
Related -LAYER displays the Freeze and Thaw options on the command line. VPLAYER freezes and thaws layers in floating viewports.
