This tool is used to delete the last entity created in the current block or drawing layer.
Activating the tool causes the entity to be immediately deleted. You may repeatedly use the tool to successively delete recently added entities in reverse order.
This tool operates by determining, for the current block or drawing layer, the order in which the entities are stored. It deletes the last sequential entity. In some cases this may not be the chronologically last entity. This is especially likely if you have just used one of the Arrange tools, such as Edit - Arrange - Optimal Path (to end), to alter the sequence of entities.
An alternative to deleting the last entities in this way is to use the Undo tool.
