AutoLISP: Attribute to text (mtext)

Here is a rare LISP routine. there are plenty of routines out there that take an exploded attribute and turn it into either text or mtext. But this routine allows you to make mtext objects out from attributes without exploding any blocks.

To use this routine:

  • ATTMT <enter> to start
  • Specify the height that you want the mtext to be.
  • Select the blocks with attributes
  • <enter> to make the mtext objects and end the command

NOTE: The mtext that is made will show the tag and the tag value. So if you want a very fast way to extract data, this will save you a lot of time.
