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.

Here are the results of EXPLODE for each of the following types of objects:

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

Explodes planar faces into regions.

Nonplanar faces explode into surfaces. (Not applicable to AutoCAD LT.)

Annotative Objects

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

Arc

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

Array

Explodes an associative array into copies of the original objects.

Block

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.

When nonuniformly scaled blocks contain objects that cannot be exploded, they are
collected into an anonymous block (named with a “*Eâ€‌ prefix) and referenced with the
nonuniform scaling. If all the objects in such a block cannot be exploded, the selected
block reference will not be exploded. Body, 3D Solid, and Region entities in a nonuniformly
scaled block cannot be exploded. (Not available in AutoCAD LT.)

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.

Blocks insert with MINSERT cannot be exploded. (MINSERT is not available in AutoCAD
LT.)

Body

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

Circle

If within a nonuniformly scaled block, explodes into ellipses.

Leaders

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

Mesh Objects

Explodes each face into a separate 3D face object. Color and materials assignments
are retained. (Not available in AutoCAD LT.)

Multiline Text

Explodes into text objects.

Multiline

Explodes into lines and arcs.

Polyface Mesh

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

Region

Explodes into lines, arcs, or splines.
