What is this kind of block. and How to purge?

[Jeff_M]

The file has a lot of linetypes (41552) from a MicroStation file. Deleting the dictionary holding these linetypes then allows those anonymous blocks to be purged and the file goes to ~460kb. I used this lisp to remove the linetypes:

Code - C#: [Select]

1. (defun c:deldgnltstyle ( / dicts dict)
2.   (setq
3.     dicts (vlax-get (vla-get-activedocument (vlax-get-acad-object))
4.                     'dictionaries
5.           )
6.  )
7.  (setq dict (vlax-invoke dicts 'item "ACAD_DGNLINESTYLECOMP"))
8.   (princ (strcat "\nDGN Linetypes before: "
9.                  (itoa (vla-get-count dict))
10.          )
11.   )
12.   (vla-delete dict)
13.   (princ "\nACAD_DGNLINESTYLECOMP Dictionary removed!")
14.   (princ)
15. )
16.

I used AutoCAD's AECTOACAD command and it dropped the file down to 45kb.  BOOM!!
