            Icon: 
Alias: X
Description
Reduces complex entities to simpler ones, such as blocks into constituent parts, and polylines into lines and arcs.
Note: Entities on frozen and locked layers are not
               exploded.
         Method
The result depends on the entities you selected:
- Polylines become lines and arcs. Width is lost.
 - Regions become lines, arcs and splines.
 - Dimensions becomes lines, text, and solids (arrowheads).
 - Blocks become individual entities and nested blocks. You may need to use Explode
                  a second time.Note: Only blocks that have Explodable property set can be exploded. Non-Uniformly scaled blocks can be exploded only if EXPLMODE=ON.
 - ByBlock colors and linetypes may change.
 - Attributes revert to attribute definitions.
 - 3D surface entities become 3D faces.
 - Meshes become 3D faces.
 
Note: Simple entities, such as line and circles, cannot be
               exploded.
