AEDD260Lecture07 Introduction to AutoLISP programming

This is lecture 07 in the course CAD Management at Southern Maine Community College. It introduces a number of key concepts in AutoLISP programming.

Wow!!! In just 2 hours, I learned and understand more than the 7.5-hour AutoLISP programming course I took at UDEMY. How I wish I found this channel before. I lost the appetite of learning AutoLISP because of that course. I really thought that Autolisp programming is hard. But this video that you create sir changes everything. You just reignite my passion to learn Autolisp. I really do believe that teaching is a skill, and you have that great skill sir of teaching. Not all teachers have that. Now, I am hook to all of your videos here in KZbin. You just got a fan and a subscriber too sir. Congrats to your very informative channel sir. God will bless you more.

Bernard, You are most welcome. I think all AutoCAD users should be comfortable with AutoLISP programming and wish that most books and workshops would emphasize the ease with which useful commands and automation can be developed. My purpose in creating this channel was to support my classes at Southern Maine Community College. I made them public to make it easier for students to find them without having a link. Comments like yours make me glad to have done that. I you are interested, our credit classes are available online to anyone. This particular class is full for the coming semester, but if you are interested in taking it in the future, you would be welcome. It is entirely online, so these videos constitute the bulk of the presentations. I do schedule open sessions weekly for students, and evaluate all their work, of course. Dan Abbott

@@DanAbbott-SMCC I really love your video tutorials sir. You made it so easy to understand and follow along. I would love to take that credit class you had mentioned in you community college if my schedule permits. How much would that be sir? I hope I can afford that. Thank you for creating this wonderful channel sir. I'm gad I found it. Advanced happy new year to you and to your family sir...

Thanks

Que deleite de este buen material, gracias maestros

[@DanAbbott-SMCC]

You are very welcome. (Eres muy bienvenido)

[@crb2126]

Thanks u

[@sthmedia9635]

This is great. Glad I found you. Now I can and will learn LISP.

[@DanAbbott-SMCC]

Glad to hear it!

[@Evaristo347]

Thank you. Great video and an excellent instructor.

[@DanAbbott-SMCC]

You are welcome.

[@i.m.engineer1197]

Thanks. Great video.

[@DanAbbott-SMCC]

You're welcome.

[@PANDURANG99]

I am a professional Autolisp developer, it was helpful 🔥

[@DanAbbott-SMCC]

Well that is great to hear. Glad it was helpful.

[@joeperk24]

Very good lecture. Would love to sit in on one of your classes.

[@DanAbbott-SMCC]

Glad you enjoyed it. This is the first lecture on AutoLISP for an online class I teach. There is a second lecture on AutoLISP as well.

[@joeperk24]

@@DanAbbott-SMCC I'll definitely be watching it then:) if I understand right, that's your book? Or is it a book you bought and added material to? I'm trying to find a good book to help me learn autolisp. I have been finding material to supplement my knowledge of AutoCAD to be more versatile in the workplace.

[@DanAbbott-SMCC]

That is my book.

[@swalehhussein694]

I love your lecture. I spent a lot of time trying VBA for AutoCAD and i gave up entirely on programming lisp files. But now I have a renewed sense of hope and enthusiasm. Is it possible to have access to the book? and maybe what way can someone reach you in case they need to (if that's ok with you) ?

[@DanAbbott-SMCC]

The book this is taken from -- AutoCAD: Secrets every user should know -- is still available from Sybex and there are many used copies of it available from various sources. Although I wrote it in 2006, I intended it to be a best-practices book and the only things I would change would be to add chapters on annotative entities and dynamic blocks. You can reach me at [e-mail] if you have a question. If I have time, I'll try to answer it.

[@NathanEllery]

I still use toolbars for osnaps because I can hit the toolbar in the middle of a command and change osnaps on the fly. 'osmode .... Not sure you can do this via Autolisp because you have to exit out of the current command. I have several toolbars with my favourite settings.

[@DanAbbott-SMCC]

I like toolbars as well -- I minimize the ribbon and have a custom toolbar that includes the layers toolbar on so I can use the controls quickly and other tools that I use frequently, like Matchprop. I usually just type an osnap override though, but I've been doing that for so long that it just happens.

Hello, Daniel. You are an amazing teacher. Thank you for the video. Would it be alright if you take on DCL and its AutoLISP code? Thank you.

[@DanAbbott-SMCC]

Thank you for the kind words. You are very welcome for the video, but I don't find DCL to be useful enough for the things I've done to do a video about it. There are probably other videos on KZbin that could be helpful. The kind of automation I've done with AutoLisp doesn't require dialog boxes, which in some cases might even get in the way. See this video for an example of what I'm referring to. kzbin.info/www/bejne/hYnbqHhjqrRqY8U

[@halcyondrafting7869]

Hi, Daniel. Thank you for the tutorial. May I know where to purchase your book?

[@DanAbbott-SMCC]

You can get it on Amazon as a new or used book.

[@ibrahimpatel9006]

How can I get this AutoCAD_Secrets_entire_book.pdf

[@DanAbbott-SMCC]

This video is for my students, for whom I have purchased a copy of the book and placed on an internal server as a reference for them. It is not available to the general public. You might be able to find a website that is selling the entire book as a PDF, or you can purchase a used copy if you want a hard copy. I know that Amazon often has links to used copies of the book. You can also still buy the book new from Amazon or Sybex.

LISP to explode block and make block again with the same name

[@DanAbbott-SMCC]

I am not sure what you are trying to do. Why do you want to explode a block and then remake the same block with the same name?

[@SH-pu9mk]

Hi man, do you know if there is a way to automate drawing road / footpath edges on an image in autocad LT or can it be done at all using a different software ? Thanks in advance for your answer.

[@DanAbbott-SMCC]

You can use the IMAGE command to insert an image, then scale it, if necessary, and sketch lines over it. Make sure that you use DRAWORDER to place the image under the lines. You will have to trace the edges -- I would use the PLINE command. There is no way to automate that process from the image directly that I have found to be effective.
