Autodesk wants your input again in its annual API survey. This used to be a closed survey for Autodesk Developer Network (ADN) members, but has been open to all for the last few years. If you do any AutoCAD-based development at all, I encourage you to take part. That includes those of us who do most of our development in LISP.
Here’s the direct link to the survey. As you can see if you click the link, there’s a lot of stuff in there that assumes you’re keen to get developing for AutoCAD WS. If you’re not quite so filled with Cloudy enthusiasm and would prefer Autodesk to expend its resources elsewhere (on fixing and improving Visual LISP, for example), please fill in the short survey and say so. It closes on 22 June, so you only have a week.
Why bother, when it’s obvious that … Full post
…LISP. I have now closed the What are the best features ever added to AutoCAD? poll, and the winner is AutoLISP/Visual LISP, by a long, long way. I don’t always agree with the majority view expressed in the polls here, but in this case I wholeheartedly agree. Adding LISP was the biggest and best thing that ever happened to AutoCAD. Autodesk owes an enormous debt of gratitude to John Walker for incorporating the work of David Betz, who was of course standing on the shoulders of John McCarthy. It’s a crying shame that Autodesk has been so terribly neglectful of Visual LISP for over a decade.
Here are your top ten “best ever” AutoCAD features:
- AutoLISP / Visual LISP (32%)
- Paper / Model Space / Layouts (21%)
- Xrefs (20%)
- Copy / Paste between drawings (19%)
- Dynamic Blocks (16%)
- Object Snaps (15%)
- Layer Visibility per Viewport (12%)
- Undo (12%)
- Grips … Full post
Autodesk wants your input in its annual API survey. What used to be a closed survey for Autodesk Developer Network (ADN) members has been open to all for the last couple of years, and if you do any Autodesk-based development at all I encourage you to take part. Yes, that includes those of us who do most of our development in LISP. In fact, I am especially keen to see LISP developers adequately represented in this survey.
This is a one-page survey and it doesn’t take long. The full list of API surveys is on Kean Walmsley’s Through the Interface blog. Most of you would be interested in the AutoCAD survey, so here’s a direct link to that.
Kean assures us that our feedback will not fall on deaf ears, although I have yet to see any evidence of that in terms of any change to Autodesk’s decade-long … Full post
Here in Australia it is well into the 21st and I raised my own glass last night, but for John McCarthy and most of my readers, it is the 20th of October right now. So this is the appropriate time to say Happy Birthday to LISP. Here’s to another 50 years of simple, compact, maintainable, efficient and elegant coding.
It is difficult to find an exact date for LISP’s birthday. It wasn’t so much born in an instant as it was gradually dragged out of the primordial slime during the heady days of late 50s computer research. What is known is that John McCarthy, LISP’s “father”, published a report in October 1958 about his new programming language aimed at providing artificial intelligence capabilities on the IBM 704 mainframe computer. That report, one of a series, was the first one to use the name LISP.
OOPSLA, a major annual conference on object-oriented programming, has decided to celebrate LISP’s 50th birthday on 20 October 2008. Practically everyone at that event is likely to be smarter, geekier and possibly even more pedantic than me. So for now I’m going to go with that date and raise a glass to LISP and John McCarthy in one week’s time.

Warning, CAD nerd stuff ahead. This is a long and technical post and if you’re using AutoCAD in a largely out-of-the-box state you probably won’t care about any of it.
If your modification of AutoCAD extends beyond the trivial, you may find it useful to know what AutoCAD loads, and in what order things are loaded. It is possible for LISP files in particular to tread on each other’s toes, so knowing what gets loaded when can be useful information for diagnosing such clashes. This post aims to provide that information. It uses AutoCAD 2009 as an example, but the same principles apply to all releases from AutoCAD 2006 onwards.
On startup, the first things AutoCAD loads are its CUI files. It first loads the Enterprise CUI file, then the Main CUI file, then any partial CUI files attached to the Main, then any partial CUI files attached to the … Full post
Yes, that includes hacking about (or producing beautifully elegant code) in LISP. If so, you may wish to go here and fill in the appropriate API survey, which is probably the AutoCAD one.
This year, Autodesk is opening up this survey, which used to be confined to Autodesk Developer Network members. I approve. ADN represents a tiny (but important) minority of fee-paying developers approved by Autodesk. I expect the results will be rather different if a significant number of “normal” AutoCAD developers notice this survey and fill it in.
If you are, say, a LISP or VBA user and are feeling neglected, please go and have your say while you have the chance. The survey closes on 1 May.
Greg Robinson, who I had the pleasure of meeting at Autodesk some 11 years ago in the run-up to Release 14, has started a Wiki for AutoLISP and other AutoCAD-based source code. I’m a big fan of LISP in AutoCAD, so I’m happy to see this resource available for users.
It’s in its infancy right now, but if you pick the All Pages link you’ll see that there already dozens of routines available, one of which may help you with something you need to do. Here’s the link to the main page:
