AutoLISP & Dynamic Blocks - Part 1

**Note*** I only just noticed the red rectangle on the screen as I was uploading the last video in this playlist. Unfortunately it will have to stay that way for a while as I won't have time to re-export and upload these videos in the near future. Hopefully it's not too much of a distraction. This series covers some advanced topics in AutoLISP programming. You'll see how I actually code. I only had this weekend to complete this whole project, start to finish, so unfortunately that means no re-takes or preparation. None the less, if you want to see more advanced AutoLISP code in action, and can spare a few hours, this playlist is for you. First, we make a very useful Grid Bubble dynamic block. This block works great on it's own, no LISP required, but also serves as a great vehicle to demonstrate some advanced LISP techniques. Thereafter, we build a LISP routine from scratch that will 1) Automatically adjust the grid number (and letter) sequences, and 2) Apply an alignment property to the block. IMPORTANT: If you create your own block, either use the same attribute and property names as me, or make sure you adjust your own code to suit.
