To Explode a Block Reference

You can convert a compound object, such as a polyline, dimension, hatch, or block reference, into individual elements.

Use this procedure to break an inserted block reference into its component parts without affecting the block definition.

1. Click Drafting tab > Modify panel > Explode.
2. Select the objects to be exploded.
Note: If you explode a block with attributes, the attribute values are lost, leaving only the attribute definitions. The colors and linetypes of objects in exploded block references can change.
