AutoCAD virus protection update

As I mentioned in my last post, I had some reservations about the code provided by Autodesk to deal with suspect acad.vlx and logo.gif files. Based on a suggestion from Jimmy Bergmark, I have written my own, safer version which you can download here: clean_virus_safe.lsp.

The comments at the top of the clean_virus_safe.lsp file explain what to do with it, but I will reproduce some of the relevant points here.

  • Purpose: Checks for existence of acad.vlx and logo.gif files, which are associated with virus AL/Logo-A, also known as ACAD/Unexplode, ACAD/Agent.A or ACM_UNEXPLODE.B. Written as a safer alternative to Autodesk’s code which deletes suspect files without prior warning. This code renames the files instead.
  • Legal: Provided as-is with no warranty whatsoever, use at own risk. May be distributed freely.
  • Usage: Append the contents of this file into a startup LISP file (e.g. acaddoc.lsp in your search path – … Full post

Another AutoCAD malware warning

Shaan Hurley has posted some useful information about another AutoCAD-based virus that is doing the rounds, and I strongly suggest you read it. However, I have some reservations about the solution that is posted there and in the Autodesk knowledgebase.

The LISP code suggested will delete any files called acad.vlx or logo.gif that are located in the current user’s current AutoCAD search path. There are a couple of problems with that.

  • The search path will change depending on the user, the profile, the startup folder and the drawing folder. That means you can’t just use the code once and expect the problem to go away; the code will need to remain in place permanently to ensure it does not recur. That may not be a huge problem, although it will have a performance penalty (particularly where the search path is long and/or includes network paths) … Full post

The biggest DWG file I’ve ever seen

Today, I tried to investigate a DWG file that one of my users couldn’t open. It wouldn’t open for me on an old 1 GB PC. Trying a PC with 4 GB didn’t help, and neither did experimenting with various releases of AutoCAD. Depending on the release, AutoCAD would either try to open the drawing and eventually die with an out of memory error, or would instantly inform me that the drawing was too big to open. I don’t have access to a 64-bit version of AutoCAD (which might possibly be able to open this monster on a PC with more than 4 GB of RAM), so the drawing is effectively useless.

The drawing is 242 MB (254,145,119 bytes), which I’m pretty sure is the largest drawing I’ve ever encountered. Based on a plot of a previous revision of the the drawing, it should be about 200 to 300 KB, … Full post

AUGI Special Election – voting opens

The AUGI Special Election voting page is now live, and will be open until 12 July 2009. I encourage all AUGI members to carefully consider the candidates and participate in the electoral process.

I do not like some of the restrictions that have been placed on this election, but it is the first real election (i.e. with a choice of candidates) that AUGI has had for several years, so please make it a success by taking part.

AUGI Salary Survey – last few days

The annual AUGI Salary Survey (ably run by friend and fellow geek/blogger Melanie Perry) is open for your responses until 30 June,  so if you’re planning to fill it in, please get in soon. There are 19 simple questions on one page, and it only takes a couple of minutes. If you have questions about the survey, read the FAQ.

In these troubled times, many of you may find the previous years’ results a valuable resource.

AUGI | AEC EDGE magazine published

More AUGI news, but good news this time. The first edition of the on-line magazine AUGI | AEC EDGE has been published by Extension Media. It is available in high- and low-res PDF format, plus an on-line reader. The first issue has 82 pages of almost entirely Revit articles and is very light on for advertising. That’s good in the short term for readers who prefer editorial content over advertising, but in the long term the advertising ratio will have to ramp up to ensure this publication’s ongoing survival.

In the meantime, I commend the advertisers who did contribute to making this publication a reality: Contex, Advanced AEC Solutions, CADzation, Autodesk Catalog, Autodesk Seek / Revit Market and HP (although I may not be so kind to HP in future posts on this blog). I also commend Editor (and AUGI Director) … Full post

AUGI Special Election – Candidates

A touch of Tehran taints the AUGI Special Election

Most of you reading this blog are fortunate enough to live in democracies, and can only look on with sympathy at those who are denied the right to choose who represents them. What must it be like to live under regimes where the people are denied basic rights such as a free choice over who governs them? Or under mock-democratic regimes that hold “elections” where the candidates available from which to choose are strictly limited, or where the ruling regime changes the rules of the game to prevent losing its majority, or where the right to comment on the suitability of candidates is removed?

Well, I guess we AUGI members now have a slight inkling of what that is like.

OK, so that’s over the top. At AUGI, there are no riots in the street, no fires, no guns, no dead protesters. No election fraud, either, and I … Full post

Hotfix available for Raster Design licensing issue

Thanks to Brian and Rick for pointing out the availability of a hotfix for Raster Design 2010’s standalone/network license incompatibility. As a bonus, it also fixes some Raster Design / Civil 3D stability issues.

The hotfix is available here, and as always with patches, fixes, service packs and updates, read the readme first.

Note that although this fixes the most common scenario where a network Raster Design needs to work on a standalone AutoCAD, it does not fix the opposite scenario. So if you have a bunch of network licensed AutoCAD variants available to you and you have a standalone license of Raster Design because you’re the only person in the office who needs it, you’re still out of luck. If you’re in such a position, I think you have a very strong case for a no-cost change from standalone to network licensing for Raster … Full post

AutoCAD 2010 – Putting things back to “normal”

Edit: If you’re running a more recent release of AutoCAD, have a look at the post AutoCAD 2017 – Putting things back to “normal” instead.

Easily the most popular post on this blog, in terms of both hits and comments, is AutoCAD 2009 – Putting things back to “normal”. Lots of people seemed to find it useful, so I guess it’s worth doing an updated sequel for the current release. Much of this post is the same as the original, but there are differences.

Note: there are updated versions of this post for AutoCAD 2011 and 2012.

One thing that’s regularly asked whenever a new AutoCAD release hits the streets is how to make it work like earlier releases. As I stated in my original post, I think you should give any new features a fighting chance before turning them off or ignoring them. The … Full post

The 12-month cycle and shipping software with known bugs

In a recent blog post, Deelip Menezes appears to be shocked by the very idea that a particular CAD company (no, not Autodesk) would ship software that contains known bugs. I thought he was joking, because he’s surely aware that practically all software companies with highly complex products release software with known bugs. As Deelip points out, those companies with 12-month cycles are particularly prone to doing this. There is no possible way any company can release something as complex as a CAD application within a fixed 12-month cycle without it containing dozens* of known bugs (because there isn’t time to fix them after discovery) and dozens* of unknown ones (because of insufficient Beta testing time).

Reading Deelip’s post and subsequent comments more carefully, it becomes clear that he doesn’t mean what a casual glance might lead you to believe he means. Deelip makes a specific distinction between … Full post

AutoCAD for Linux – another bad idea

I often see calls for Autodesk to support AutoCAD on Linux. Just like AutoCAD for the Mac, while I can sympathise with the users of that OS, I think a native port of AutoCAD for Linux would be a bad idea. Again, I think it would be bad for everybody: Autodesk, AutoCAD for Windows users, and most of all, AutoCAD for Linux users.

Why? First of all, for most of the same reasons I gave for the Mac port. Autodesk hasn’t just failed in the past with AutoCAD for the Mac, it has failed with AutoCAD for Unix, too. I remember Autodesk being very enthusiastic about the Sparc port in particular (AIX, too). I know personally of customers who were caught up in that enthusiasm and invested heavily in a Unix environment, only to bitterly regret it a few years later when Autodesk abandoned them. Would this happen again? … Full post

Go and snag a free Snagit, quick!

For the next few hours, you can get a free registered version of the screen capture software Snagit from TechSmith. It’s a couple of versions old and not supported on Vista, but nevertheless is well worthwhile. No, the Print Scrn key isn’t the same thing at all; Snagit is much, much more useful than that. Try it for yourself, you can thank me later.

To get the freebie, first get a registration key by clicking here and then download your copy of Snagit 7.2.5 from here. Be quick, because this offer closes at 5 PM EST (9 PM GMT/UTC) today, 5 June 2009.

Even if you were planning on buying the latest version of Snagit, get this freebie anyway. As a registered user of Snagit, you automatically qualify for upgrade offers. This means you can get the latest Snagit for US$24.95 rather than US$49.95 (depending … Full post

AutoCAD for Mac review in Cadalyst (circa 1989)

A comment from Kal on Between the Lines mentions an AutoCAD Release 10.5 for Mac. My memory of ancient and useless AutoCAD trivia is usually pretty good, but this time things are a bit foggy and I need some help. I definitely remember there being some kind of half-release of AutoCAD for Mac*, but I’m not sure it was an official designation.

I do remember a Cadalyst review at the time, possibly by Art Liddle. I would estimate it to be from 1989, give or take a year. The then-new Mac release reviewed was some kind of hybrid between R10 and R11 (I think), with most of the feature set of one release and the DWG format of another. I had thought the product was called R11, but I could be wrong about that and maybe it was 10.5.

Is there anybody out there with a complete … Full post

Why AutoCAD for Mac is a bad idea

There has been a fair bit of open discussion from Autodesk lately on the subject of a possible future OS X AutoCAD version. The more I think about this, the more I am inclined to believe that this would be a bad idea. A very bad idea.

It pains me to write this, because I’m very much a user advocate and I’m arguing here against something that some users have been requesting for a long time. If you’re one of those users, I’m sorry, but I think this is one of those cases when giving you what you want would be bad for everybody, and bad for you in particular.

Now, this sort of platform discussion often degenerates into a quasi-religious debate, so let’s see if I can head it off at the pass. If you’re a Mac fan who wants to tell me the benefits of your chosen … Full post

Autodesk’s Revit rebellion reaction

It’s time to examine how Autodesk has reacted to the widespread criticism of Revit 2010. Is Autodesk listening? To be more specific, is Autodesk’s Revit team listening?

The Good

It has been good to see extensive public participation by Autodesk people in various discussions in different places. The Revit team isn’t hiding. It is asking for feedback on the Autodesk discussion groups, the AUGI forums and its own blogs, and getting lots of it. Much of it is negative, but it is to Autodesk’s credit that I’m not seeing much in the way of denial, or demands that the criticism must be constructive. I’ve been trying in vain for years to convince some people at Autodesk that denial is counterproductive and that criticism doesn’t have to be constructive to be useful.

The sort of messenger-shooting that I’ve seen some Autodesk people do from time to over the years (*cough* … Full post

AUGI World’s missing column

Despite living in troubled times, AUGI is managing to keep its AUGI World publication going, at least in electronic form. The printed edition, which was previously available only in North America, is no longer with us due to printing costs and/or green intentions. It may or may not not return at some later date.

AUGI World current and past issues

I was happy to note that not only is the current copy available in PDF format, but that previous issues have also been made available in that format. The unpopular NXTBook experiment is over, it seems.

Another change you may notice this year is that David Kingsley’s On The Back Page column is no longer with us. David, a former AUGI Director, is a very vocal critic of the current AUGI Board of Directors. The Board decided that the column he submitted was not deemed suitable for … Full post
