Menu: Block > Edit Block from Reference
Shortcut: B, D

With this tool, a block can be edited by choosing an existing block reference entity. This is useful and usually faster if you don't know the name of the block you want to edit.
The block is opened for editing. To return to the main drawing (called "*Model_Space"), edit block "*Model_Space" or start the tool "Edit Main Drawing" in menu "Block".
