hi again!
I have an xref with 300 blocks in it... 200 are blocks named "KS 1_3" and 100 are named "KS_1_2"
these two block types are regular blocks (two rectangles, one inside the other, and two polylines making a cross through it, to represent a Cable box), with the only difference being the size of the blocks themselves (the KS 1_3 block is a bit bigger/is a larger
 
i have created two dynamic blocks which i want to REPLACE these 300 blocks with. The dblocks i have created have annotatable text (box reference number) and the box itself can be independently rotated so the text is always upright.
 
I know how to replace blocks for blocks but I need to be able to replace blocks for DYNAMIC BLOCKS and have their names updated at the same time.
 
(the only method i know for block replacement is explained here:
http://www.dailyautocad.com/2007/10/replacing-block-in-drawing-with-another_15.html and as you can see, the block name doesnt change, nor does it work for dynamic blocks)
 
 
any insight for a struggling engineer?
