## Function Description:
Sometimes a designer sends drawings to other people, but doesn't want others to modify the drawings. The Drawing Lock function can turn the drawing into a whole block. You can't explode it or modify the objects of the original drawing. It is a good way to prevent others from modifying the drawing.
**Note:** Please save your drawing before using this command, because the locked drawing can't be modified.
