Subject: Locking and unlocking layers

Locking a layer makes it easy to refer to information contained on the layer, but pre­vents you from accidentally modifying its entities. When a layer is locked (but visible and thawed), its entities remain visible, but you cannot edit them. If you lock the cur­rent layer, you can still add new entities to it. Unlocking a layer restores full editing capabilities.

   1   Do one of the following to choose Explore Layers ():

•   On the ribbon, choose Home > Explore Layers (in Layers) or choose Tools > Layers (in Explorer).

   2   Click in the Locked column for the layer you want to lock or unlock.

   3   To complete the command and return to your drawing, close the window.

Select an entity that is assigned to the layer you want to lock or unlock.
In the command bar, type LAYBYENT and choose Lock or Unlock or type LAYLCK or LAYULK, then select an entity that is assigned the layer you want to lock or unlock.

To specify how faded entities on locked layers display
