Explode Vs Ungroup
UNGROUP removes all objects from the current group.
The following prompts are displayed.
Select group or [Name]:
If a group contains sub-groups, you are promted to Accept to ungroup the current selection or choose Next to cycle through the groups in the selection set.
To understand UNGROUP the user must understand GROUP:
Group Objects
A group is a saved set of objects that you can select and edit together or separately as needed. Groups provide an easy way to combine drawing elements that you need to manipulate as a unit.

- Overview of Groups
- Create Groups
In addition to choosing the objects that will become the members of a group, you can give the group a name and description.
- Select Objects in Groups
There are several methods for choosing a group, including selecting the group by name or selecting one of the members of the group.
- Edit Groups
You can modify groups in a number of ways, including changing their membership, modifying their properties, revising the names and descriptions of groups, and removing them from the drawing.
EXPLODE
Quick Reference
Breaks a compound object into its component objects.
Access Methods

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.
NoteIf you're using a script or an ObjectARX® function, you can explode only one object at a time.
- 2D and Lightweight 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.
- 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.
- 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 “*E” 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.
Exploding a block that contains attributes deletes the attribute values and redisplays the attribute definitions.
Blocks inserted with MINSERT and external references (xrefs) and their dependent blocks cannot be exploded.
- 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.
- 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.
The distinguishing difference between the two is quite apparent after reading and comparing the definitions and usages of each from HELP.
I would suggest that you were'nt dealing with a group, more likely a single polyline or possibly a block reference. Neither of those is a group so UNGROUPing them would naturally not have a result, whereas EXPLODEing them would.
