What is the difference between turning off a layer and freezing it

While I was conducting the training, over a GoToMeeting, he was performing other work on the project and just listening in. How are they Different? OFF - Can be made the current layer.

OFF - Blocks with multiple layers might still be partially visible, even if the layer the block is inserted on has been turned OFF. Other Layer Controls:. LOCK - Unlike freezing or turning off a layer, when you lock a layer, it is still visible, just not able to be manipulated at all.

If I have missed any differences or caveats to these to functions, please let me know in the comments. You cannot edit objects on a locked layer. Locking a layer is useful if you want to view information on a layer for reference but do not want to edit objects on that layer. Controls whether the selected layers are plotted. If you turn off plotting for a layer, the objects on that layer are still displayed.

Turning off plotting for a layer affects only visible layers in the drawing layers that are on and thawed. If a layer is set to plot but is currently frozen or off in the drawing, AutoCAD does not plot the layer. Turning off plotting for layers containing reference information such as construction lines can be useful. Freezes selected layers in the current layout viewport. You can freeze or thaw layers in the current viewport without affecting layer visibility in other viewports.

Frozen layers are invisible; they are not regenerated or plotted. Thawing restores the visibility of the layer. Turning a layer off does indeed make it so that every object on that selected layer is not visible to the user.

However, that layer can still be erased or moved; for example, if the user were to perform an Erase All or Move All operation. Freezing a layer also makes all objects on that layer invisible to the user, but it has a few other important benefits.

If an Erase All or other similar operation is completed, it will not erase layers that are frozen. Another benefit of a frozen layer is that objects on that layer are no longer using system memory for operations such as regen, redraw, zoom, and pan, which can be a real benefit for drawings with very large objects or data sets. To summarize, turning a layer off should be thought of as more of a temporary state in order to increase screen visibility for a particular moment.
