Why digitally sign your LISP files?

 , , , , , , , , , itemprop="discussionURL"4

After I mentioned in an earlier post that I had digitally signed the sample LISP file I had provided, this generated some interest. In this post, I’ll explain why you might want to sign your LISP files. In a later post, I’ll explain how to do it. These days it is standard practice for developers to digitally sign their code. Operating systems and applications are displaying increasingly scary warnings when coming across unsigned code. Here is an example of the sort of message you get when you load an unsigned LISP file into AutoCAD from a location that has not …

Setting your application or document window size using LISP

 , , , , , , , , , , , , , , itemprop="discussionURL"1

I intend to produce a few videos containing tips, tutorials, product comparisons and the like. I’ve set up a cad nauseam YouTube channel, but don’t bother visiting it yet because it’s empty. One of the things I need to do for these videos make sure I’m capturing the screen at an appropriate resolution. I knocked up a bit of Visual LISP to take care of this task quickly and accurately, and you might as well have it. It’s a simple routine that allows you to accurately size either the main AutoCAD application window or the current document window (drawing area) …

Yet more Autodesk software falls off the perch

 , , , , , , , , , , itemprop="discussionURL"3

Just when I thought I was having a nice vacation from tending the Autodesk Graveyard (see also Autodesk products are falling like parrots), another bunch of former best-thing-ever products have bitten the dust. This time, it’s Autodesk’s Gameware middleware products that have been read the Last Rites. Scaleform, Beast, HumanIK and Navigation can no longer be purchased or maintained. If you used these products, support will cease as soon as your existing maintenance agreement expires. More details on cgchannel.com. That leaves Stingray as the only surviving middleware product (for now). That’s probably only still alive because Autodesk wants the halo …

The big Bricsys interview 7 – the applications ecosystem

 , , , , , itemprop="discussionURL"1

This is one of a series of posts covering an extensive interview with Bricsys CEO Erik De Keyser and COO Mark Van Den Bergh. In this post, Erik discusses the Bricsys efforts to work with and assist third-party developers. He does this without being prompted by a question – it’s obviously very important to him. Erik: For our future growth it’s very important, the ecosystem of the applications we have now. We have talked a lot about what we are doing and about our own products, but we should maybe have spent more time on the importance of the ecosystem. …

BricsCAD documentation – a tale of three systems – part 3

In this third post in what was supposed to be a two-part series, I have more to say about the BricsCAD documentation system. See here for part 1 and here for part 2. Developer Help – Addendum In this comment from Bricsys API person Torsten Moses, he informed me about the availability of the Lisp Developer Support Package (LDSP) in the Bricsys Application Catalog. As always, when presented with new evidence I am prepared to re-examine my position on anything. Therefore, I will now further discuss the BricsCAD developer documentation. The first thing to mention is that the existence of …

AutoCAD 2018 – at last, something to praise

 , , , itemprop="discussionURL"1

This isn’t supposed to be an Autodesk-bashing blog. Really, it’s not. Sure, Autodesk (and anyone else) gets criticism where deserved. There’s been a lot of that lately, but only because Autodesk has thoroughly deserved it. I don’t make up things so I can have a go; Autodesk provides the material all by itself. Among other things, I’m a customer advocate. I don’t care who you are, act in an anti-customer manner and I’m going to slam you. Hard but fair. Dish up bullshit to your customers and I will gleefully point that out and heap derision on you. Deal with …

BricsCAD’s LISP kicks sand in the face of AutoCAD’s

 , , , , , , , , , itemprop="discussionURL"10

If you’re a power user or CAD Manager transitioning from AutoCAD to BricsCAD, one of the things you’ll like is that almost all of your LISP routines will just work. That’s not an statement that can be made about various Autodesk products that bear the AutoCAD name, such as AutoCAD 360, AutoCAD LT and AutoCAD for Mac. It’s not just simple old AutoLISP code that runs in BricsCAD, but complex dialog routines that use DCL, and Visual LISP stuff that uses ActiveX. Yes, even on the Mac and Linux platforms. Some DOSLib functions are built in and the rest can …

AutoCAD 2017 for Mac released, still half-baked

 , , , , itemprop="discussionURL"4

AutoCAD 2017 for Mac and AutoCAD LT 2017 for Mac have been released. Here’s a video highlighting exciting and innovative new features such as drawing and layout tabs. Despite such stellar advances, it’s safe to say that AutoCAD for Mac remains half-baked, even after all these years. Don’t say I didn’t warn you. According to Autodesk, these are the features missing from AutoCAD 2017 for Mac: LAYDEL, LAYMRG, LAYWALK and LAYVPI Tool palettes New layer notification Navigation bar ShowMotion Ribbon* DesignCenter** Sheet Set Manager*** Steering wheel Feature finder for help Model documentation tools Dynamic block lookup parameter creation/editing Table style …

BricsCAD startup LISP bug fixed

 , , , , , , , itemprop="discussionURL"0

In my previous post I have a real problem with BricsCAD, I related my then-latest interaction with the Bricsys support system: Steve Johnson 05-12-2016 05:30 UTC I don’t know if this is a BricsCAD problem or a DOSLib one, so I am reporting it to both Bricsys and Dale at McNeel. I’m also not sure if this was happening in earlier versions. If I load DOSLib during an S::STARTUP call and then use the (dos_msgbox) function later in that call, this fails the first time round because BricsCAD things the function is not defined. Opening a second drawing results in …

Hotfix for AutoCAD 2017 SP1 Autoloader bug

 , , , itemprop="discussionURL"2

As reported earlier, AutoCAD 2017 SP1 breaks third-party add-ins that use the officially approved Autoloader mechanism. Autodesk is to be commended for acting quickly to produce a hotfix for this. In order to make this hotfix available quickly, Autodesk has taken the very unusual step of allowing a third party to distribute it. See this post from Jimmy Bergmark, who pointed out the bug in the first place. Kudos to whoever at Autodesk made the call to think outside the box to do this. It’s a very un-Autodesk Corporate thing to do, and particularly commendable for that very reason. It’s …

AutoCAD 2017 Service Pack 1 is out but you probably don’t want to install it

 , , , , , itemprop="discussionURL"0

As reported by Jimmy Bergmark, AutoCAD 2017 SP1 will break add-ins that use Autodesk’s built-in autoloader mechanism. It looks like it’s a problem caused by third party applications, but it’s not. It’s entirely Autodesk’s fault. The only fix at this stage is to uninstall SP1. It’s astonishing that Autodesk would release a service pack like this, introducing a nasty bug that will break customers’ existing functionality. This reminds me of the comedy of errors that was AutoCAD Release 13 with its multitude of updates, many of which introduced new bugs as well as fixing others. AutoCAD 2017c4a, anyone?

Shout out to Robert McNeel & Associates

 , , , , itemprop="discussionURL"4

Let’s start the rebirth of this blog on a positive note. I’d like to express my gratitude to Robert McNeel & Associates for what must surely be the most outstanding example of long-term customer service in the CAD industry. These days, McNeel is best known for the 3D modelling software Rhino. I have heard good things about this product, but have never used it. However, I am a long-term user of another McNeel product, DOSLib. This is an extensive set of functions that adds greatly to the functionality of AutoLISP. It all works very well and has saved me many hours …

AutoCAD 2013 Help shock – it no longer sucks

 , , itemprop="discussionURL"18

Some months ago, I gave Autodesk several damn good (and thoroughly well-deserved) thrashings over its hopelessly inadequate AutoCAD 2013 Help system. When Autodesk’s Dieter Schlaepfer responded and asked for feedback, he sure got it. There are 142 comments on that one post to date, most of them leaving nobody under any illusions about how short of the mark the new system was. There is now an updated version of the AutoCAD 2013 Help system. It has been an interminably long time coming, a fact made far worse by Autodesk’s stubborn refusal to provide a CHM stopgap (which could have easily …

LISP programmers, have your say again

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 …

AutoCAD 2013 – Using Help in anger

 , itemprop="discussionURL"3

Trying to be fair, I decided to put aside my initial hostility to the AutoCAD 2013 Help system and use it for real. I used it in a realistic situation, to find out how to work with something new or changed (model documentation) as I was working through it with my own example drawing. Try as I might to give it a fair go, I could only get so far before I got irritated. Using it in anger might not be an entirely appropriate phrase for it, but it’s not that far off. Using it in annoyance, perhaps? Here’s how it went. I …

AutoCAD 2013 – Help improved in one area

 , , itemprop="discussionURL"2

There’s one important area in which AutoCAD 2013’s Help shines when compared with its immediate predecessors. If you’re a Visual LISP user, you’ll be pleased to know that if you select a function name in the editor (e.g. (vla-get-ActiveDocument)) and hit Ctrl+F1, this now takes you to the appropriate page in the ActiveX and VBA Reference, as it should. In AutoCAD 2011 you just got a cryptic message or a 404 error, depending on the context. In AutoCAD 2012, you were just taken to the front page of Help and expected to find it yourself. Props to Autodesk for fixing …

Autodesk’s Kean about moving to the Cloud

Autodesk’s API guru Kean Walmsley is the second Autodesk person I’ve seen who has been brave enough to stick his head above the parapet by discussing the Cloud, in writing, and in a medium that allows for public comment. Kean has always seemed like a straight shooter to me. Please note that his blog represents his personal opinions rather than an official Autodesk position. He’s after your comments, so please go and let him know what you think on his post. Add your comments here if you’re more comfortable with that, and I’ll make sure Kean sees them.

 , itemprop="discussionURL"1

A few days ago, John McCarthy died at the age of 84. He didn’t make a fortune selling gadgets, he just profoundly affected the world of computing. He will be remembered mainly as the father of LISP, without which it is quite possible that AutoCAD and Autodesk would not have survived beyond the 80s. However, his original thinking went well beyond the development of a language. For example, 50 years ago he came up with an idea that is very relevant to what we are actively discussing today: In 1961, he was the first to publicly suggest (in a speech …

Taking control of your command line history

 , , , , itemprop="discussionURL"13

Thanks to Kean Walmsley’s post on his Through the Interface blog, I have learned something that would have been handy to know for the last decade or so, but which somehow escaped my knowledge. I learned how to increase the size of AutoCAD’s command line history cache. It defaults to 400 lines, which isn’t enough for me. I think this information deserves a wider audience than the ubergeek developers who frequent Kean’s blog, so here goes. Although it’s not directly mentioned on Kean’s post, you can find the current command line history cache length setting like this: (getenv “CmdHistLines”) This …
