Issue: 

On, Freeze, Lock in layer properties are common functions. What effects can be achieved, and what are the differences?

Solution:

  1. Layer On/Off.
    Controls the display and closure of layers. Graphics with the layer off are still participating in the operation and can be selected.
  2. Layer Freeze.
    Controls the display and closure of layers. Freeze the layer in the frozen state, which cannot be selected, and freezing the layer in big drawing can improve the speed of the software.
  3. Layer Lock.
    The graphics are displayed in the dark after locking. Locked graphic objects cannot be selected to prevent accidental modification.
