Exploding multiple blocks
You can explode many blocks at once using Insert* (CAD >Blocks & Inserts). This command makes copies of the selected blocks, placing them on the current overlay.
These copies are no longer blocks but are now made up of the items from the original blocks
This command is very useful if you have a DXF file containing a lot of block, because it will insert the blocks into an editable overlay and explode them at the same time.
These new items will also take on the precision of the current overlay's dataset. This may mean that the amount of memory required for the DXF data (which is often significant) is reduced.
