I got a drawing form an architect which all lines and blocks are dulicated (3 or 4 times above each others) ..i used the overkill but i got no result...is thier any other option to delete the duplicated drawings?

I don't have time to look at the drawing right now, but have you unchecked all boxes under the "Ignore object property" section when you run the OVERKILL command?

Overkill does not recognize identical looking blocks with different names, etc.

You could explode all and then run overkill.

Well ...even if i checked all the boxes it would'nt delete the blocks
