Drops all block occurrences to their base elements, including:
Top level block occurrences
Nested block occurrences
All block occurrences on all sheets (working, background, and 2D Model)
The original block definitions are not deleted from the file.
A dialog box prompts you to confirm or reject the action. You also can use the Undo command to restore all nested blocks.
Tip:
You can use the Unblock All command, along with the Ungroup All command, before you copy and paste imported AutoCAD geometry to a Solid Edge sketch. These commands simplify nested block occurrences and nested groups by reducing them to their lower level geometry.
