I wanted to write a routine for tagging doors, but I don't know where to start. What I'm looking to do is be prompted to select the door (which would be a block in an x-ref'd dwg), then have the routine reference either an attribute of the block, then write the size as DText (like 3/0 for a 3'-0" door). Would this be accomplished easier and more efficently with an attribute or xdata?
