Keith™,
I said you could delete items from within a drawing opened with ObjectDBX, but you couldn't purge, so I don't think I got your idea wrong. I have had problems with erasing mline definitions in the dictionary (iirc) that are in use, so you would have to search the drawing for any mlines, then save the name of the style, then make sure the style isn't in your list before you delete it.
Vinny,
You're welcome.
Correct, there is no purge method, but there is a delete method for all objects, including tables, thus you CAN iterate through all of the blocks in the block table and delete those not referenced, the same is true for linetypes, mline styles, textstyles, dimension styles, etc ...
Yup.
.. and the end result would be the same as if you had purged the drawing ...
