Have you ever come across a block that you could not explode? You might try and get this message:
Command: explode Select objects: 1 found Select objects: 1 could not be exploded. Command:
The ability to restrict blocks from being exploded was added many releases ago, but I still see a lot of users confused by this. Here is how to "fix it".
What you need to do is redefine the block and allow it to be exploded.
There is another (fairly rare) reason you might not be able to explode a block, and that is if it was inserted using MINSERT. If that is the case, the command line will tell you when you try to explode
Command: EXPLODE Select objects: 1 found 1 was minserted. Select objects: None found. Command:
In this case, you will have to erase the MINSERT and reinsert the block(s) and explode the blocks as needed, or Autodesk has an alternative method listed here on their KB.
