You can modify a single insertion of a block without affecting its definition.
Modify a Block Reference
You can modify the position, scale, rotation, and other properties of a block reference in the Properties Inspector. These changes affect only that instance of the block reference, not the block definition.
Explode a Block Reference
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 the block is exploded, you can
- Create a new block definition
- Redefine the existing block definition
- Leave the component objects uncombined for other uses
The exploded block reference is disassembled into its component objects; however, the original block definition still exists in the drawing for insertion later.
Note: You can automatically explode block references as you insert them by selecting the Explode Block checkbox in the Insert dialog box.
