in an older version of AutoCAD we modeled our electrical parts and then set a view and created blocks so that we could do "stereo instructions" for the assemblers in China.  We did it using dbx file. pc3 and then in a new drawing we used dbxin and it came up perfectly.  Now I am using Architecture 2008 and the pc3 file is no longer in the system.  How can I do the same kind of export in Architecture 2008.
 
Your help is geatly appreciated
