How to remove blocks from imported DWG

my client will send me a 2d DWG file for me to model into 3d… in the background there is loads of stuff that increase file size… i think this is hidden within blocks. see attached. how do I easy remove ?

it wont let me select all the blocks and just delete as they are all linked…

Hi

It shouldn’t be a problem to select all of them and then delete it.

some are linked so you have to start deleting in order and it gets painful so I wasnt sure if there was a quick way… thanks

Hi - if you don’t need them as blocks, you can just select the blocks and explode them.
-wim

sure ok and they they will no longer appear in the block manager?

see attached, takes forever!Screenshot_1

As Wim said run the explode block command->Allblocks. Then you can run purge to remove the blocks from the block manager.
