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.

Hi, @kcs ! Unending thanks and gratitude for your efforts and initiative to put this together. The videos on this channel definitely took a lot of time to get going, but my thanks specifically for the time you've spent learning this on your own, and then distilling the knowledge gems for your viewers. I've just about begun dabbling in AutoLISP, and been vpraciously digging up blog posts and other LISP code snippets. I see you following many of the things Lee Mac and the likes indicate as being best practice, and this tells me how much tie and effort you've spent in including all the best parts of your knowledge. Most guys would just put this kind of knowledge sharing under a paid course... To think we get to learn with you right here on youtube, its just fabulous mate !

Warm regards, many thanks, and the best wishes for the success of yur channel. I'm sure this is going to become a go-to resource soon enough for students of all skill levels. Cheers !
