Thaw layer 0, if that doesn't work thaw and turn on all layers.

Also, if you click on it first and then use some shortcut to activate explode, make sure someone hasn't changed the short cut to be "cut" .

I try to thaw and turn on all layers and it change notihing

I enter the command manually " explode'' in the command bar, it change nothing. I found that the drawing have a block in a block. If i edit the block , and explode the ''child block'' in the block editor, after that, i can explode my block.

I've seen some poorly constructed blocks but haven't seen that before. I won't go into everything that is not good about it. After you explode the block there are 6 lines and 2 blocks. All of which can be selected using Ctrl+A but, no matter how far you zoom out, you cannot see the grips. An additional explode reveals the entities from those blocks. If that were a block that I planned on using again, I would make a new one using good drafting practices.
