I have 2000 - 3000 dynamic blocks quite often in a drawing file. All these were created using the same Dynamic Block Definition.
I have cases where some (1000 or more) have (another 1000) with nearly identical insertion points. I'd like to gather these into a selection set (A). Then end goal is to be able to select those that do not have these dups. (Select ALL, Remove those in selection set A)
... any ideas what a lisp would look like to do such a feat? (or could this be done using out of the box AutoCAD?)
