Explodes a compound object when you want to modify its components separately. Objects that can be exploded include blocks, polylines, and regions, among others.

The color, linetype, and lineweight of any exploded object might change. Other results differ depending on the type of compound object you're exploding. See the following list of objects that can be exploded and the results for each.

To explode objects and change their properties at the same time, use XPLODE.

2D Polyline

Discards any associated width or tangent information. For wide polylines, the resulting lines and arcs are placed along the center of the polyline.

3D Polyline

Explodes into line segments. Any linetype assigned to the 3D polyline is applied to each resulting line segment.

3D Solid (AutoCAD drawings)

Explodes solids into surfaces and regions.

Annotative Objects

Explodes the current scale representation into its constituent parts which are no longer annotative. Other scale representations are removed.


If within a nonuniformly scaled block, explodes into elliptical arcs.


Removes one grouping level at a time. If a block contains a polyline or a nested block, exploding the block exposes the polyline or nested block object, which must then be exploded to expose its individual objects.

Blocks with equal X, Y, and Z scales explode into their component objects. Blocks with unequal X, Y, and Z scales (nonuniformly scaled blocks) might explode into unexpected objects.

Exploding a block that contains attributes deletes the attribute values and redisplays the attribute definitions.

Blocks inserted with external references (xrefs) and their dependent blocks cannot be exploded.

Body (AutoCAD drawings)

Explodes into a single-surface body (nonplanar surfaces), regions, or curves.


If within a nonuniformly scaled block, explodes into ellipses.


Explodes into lines, splines, solids (arrow heads), block inserts (arrow heads, annotation blocks), multiline text, or tolerance objects, depending on the leader.

Multiline Text

Explodes into text objects.

Multiline (AutoCAD drawings)

Explodes into lines and arcs.

Polyface Mesh (AutoCAD drawings)

Explodes one-vertex meshes into a point object. Two-vertex meshes explode into a line. Three-vertex meshes explode into 3D faces.


Explodes into lines, arcs, or splines.
