Disassemble A Block Reference (Explode) - Autodesk 057B1-41A111-1001 - AutoCAD LT 2010 User Manual

Disassemble a Block Reference (Explode)

If you need to modify one or more objects within a block separately, you can
disassemble, or explode, the block reference into its component objects.
After making the changes, you can
Create a new block definition
Redefine the existing block definition
Leave the component objects uncombined for other uses
When you explode a block reference, the block reference is disassembled into
its component objects; however, the block definition still exists in the drawing
for insertion later.
You can automatically explode block references as you insert them by selecting
the Explode option in the Insert Block dialog box.
