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. The locked entity objects in the drawings can be unlocked by entering a password, and the locked objects cannot be deleted. Other objects that pass through the locked objects can be clipped and edited normally, and the processed drawings can be browsed, printed, but cannot be decomposed or edited. It is a good way to prevent others from modifying the drawing.
