Great presentation, thanks for uploading it. Always fun to see a Zero Wing reference. I noticed that VS Code has an extension named "AutoCAD AutoLISP Extension" to assist developers in writing and debugging AutoLISP. Cheers.
Thank you very much for this professional tutorial. I hope there will be other tutorials to share with us your passion for Autolisp programming, and help me to understand and handle dictionaries, Xdata and the advanced features. Thank you so much.
AutoCAD LT only supports limited LISP functionality as of 2024. If you're having trouble getting your routines to run in LT, make sure you're using 2024 and that it complies with the restricted functionality. If you continue having trouble I'd recommend checking with your Autodesk Reseller.
thank you, i learnt cool stuff : (acad_colordlg color) but i dont understand why you writte color at the end (tblobjname "layer" layername) cool ! (nentsel) thanks
At 47:45, I assign the color of the selected object to the variable "color", and then fire the acad_colordlg with that variable, so that the dialog highlights that color.

this short introduction has cleared up soo many difficult to grasp concepts for a non-programmer like me, thank you so much.
Many thanks for the recommendation Jeremiah!

Excellent video for someone who wants to start doing Autolisp and as a basics in programming in other languages !
Thank you so much for this. I'm an amatuer programmer and I've been writing basic programs for 15 years but I learnt a lot from this.
thanks you, for all the basic foundation of the LISP, very helpful
Thank you so much, this is one of the best videos i saw about AutoLisp!!!
Thank you very much for this professional tutorial.

Thank you so much.
As a matter of fact there will be another tutorial this friday: www.landfx.com/videos/webinars/item/4863-intermediate-autolisp.html

18:34 Shouldn't be said "at zero radians" rather than "at zero degrees" ?
True, that is technically a value in radians. I just said degrees to not get into radians just yet. Especially as, 0 degrees does equal 0 radians.
Great job. Love it . Thanks for your great teaching skills.
Hi, need help with LISP
it works with AutoCAD but it Does not work AutoCAD LT. What can I do?
AutoCAD LT only supports limited LISP functionality as of 2024. If you're having trouble getting your routines to run in LT, make sure you're using 2024 and that it complies with the restricted functionality. If you continue having trouble I'd recommend checking with your Autodesk Reseller.
can you post the link for the Autolisp ref website
Please help.
How to set minimum time code in autolisp . & single User option .
Nice One, Got some good idea to start. Thanks
Thanks for this content!
Thank you so much... It was really helpful!
Thanks you. Encourage learning.
thank you, i learnt cool stuff : (acad_colordlg color) but i dont understand why you writte color at the end (tblobjname "layer" layername) cool ! (nentsel) thanks
