AutoCAD 2010 – Turning off InfoCenter

I generally avoid the still-awful Autodesk discussion groups these days, but I do hop in from time to time in the vain hope of seeing some improvement. In doing so, I occasionally pick up a gem, and that happened today. I think this one deserves a wider audience, so here it is.

In AutoCAD 2010, you can disable the InfoCenter toolbar by opening the
registry, and going to the following key:

HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R18.0\ACAD-8001:409\InfoCenter

In that key there’s a value with the name “InfoCenterOn”.

Changing that value from 1 to 0 will disable the InfoCenter toolbar.

Source: Tony Tanzillo in this thread. Note that the “ACAD-8001” part will be different if you use a vertical variant of AutoCAD.

Why would you want to do this? To improve startup times and reduce annoyance. Autodesk should have provided a better mechanism for doing this. The absence of convenient, designed-in off switches for new features is something I’ve complained about on many occasions over the years. Autodesk’s response has been patchy.

Edit: I just noticed Owen Wengerd has posted about this, including a LISP routine to simplify the process of turning it on and off.

Autodesk answers – 4 of 4

The final question is from metis:

Q: why is program size increasing and performance dramatically decreasing as hardware specs dramatically increase? as features “improve” and are added functionality should not be removed, and code should be streamlined.

seriously aren’t there any real programmers out there anymore? this thing isn’t written in java by a bunch of scriptkiddies (although 2009 sure is skinned like it was).

A: We made a number of performance improvements in AutoCAD 2010 over the previous release, and would appreciate hearing from you if you are encountering significant performance slowdowns with this latest release. If so, please send us details on what you were doing at the time, sample files if possible, and details on the machine you are using. This will help us improve performance further in upcoming releases of AutoCAD.

AutoCAD performance and productivity

I have closed the performance and productivity polls as described in my posts here and here, and the results can be seen in the Polls Archive. As with most of the other polls I’ve run here, the distribution of votes has not changed greatly after the first few days.

It is clear from the very different voting patterns in the two polls that blog nauseam readers are smart enough understand the difference between the two questions. The performance poll has a very clear skew to the “slower” side. This supports the empirical evidence I’ve seen elsewhere that people perceive AutoCAD as getting slower. This is stuff they’ve noticed for themselves, not a few milliseconds here and there.

On the other hand, the productivity poll results show a much more even distribution. The five options are pretty equally represented, except that “a lot more productive” has suffered at the hands of the most popular choice, “a bit more productive”. If you calculate the mean result, it is almost bang in the middle. It’s actually slightly worse than that, but by such a very small margin that it is not statistically significant.

Overall, we can say that the average viewpoint expressed here is that people clearly see AutoCAD as getting slower, but that its productivity has stayed about the same. So, does this let Autodesk off the performance hook? If a slowing AutoCAD is balanced by productivity-enhancing features, does performance matter? In my opinion, the answers to those questions are no and yes respectively.

It’s not a safe assumption that productivity features are balancing speed issues for everybody across the board. A new feature may help some users’ productivity, maybe even a majority of users, but it won’t help everybody. Some new features even harm some people’s productivity, which is one more reason for being grateful that Autodesk generally lets us turn them off (although it has been forgetful about that in some cases in recent years). Performance is one of the many things that impact productivity, but unlike most new features, is something that impacts the productivity of everybody. Even a first-time user has to sit around waiting for AutoCAD to start up, while a fast power user will be rendered less productive, and certainly more frustrated, by relatively small hesitations.

Furthermore, if AutoCAD is about as productive as it was a few releases back, is that good enough? Or should Autodesk be providing noticeably more productivity in return for our Subscription or upgrade payments? If not, why do we continue to hand over our hard-earned dollars? Why do we go through the upgrade process at all, with all its attendant costs, struggles and inconveniences?

Autodesk, please put much more effort into halting and reversing AutoCAD’s performance slide. It doesn’t have to be a competition between performance and productivity. Improve the former and the latter will also improve.

How not to do a web update

If you’re a major company and your various web-based services have evolved over time, you may have a proliferation of user IDs and some other issues to tidy up. You may be tempted to have a major overhaul.

If you think your reputation among your customers isn’t low enough and you desperately want this update to be an unmitigated disaster, what should you do? If you’re dropping subtle hints about moving towards a Software as a Service model, how can you remind people about the excellent reasons that exist for avoiding dependence on on-line services in general, and on yours in particular? Here are some suggestions:

  • Do everything at once. Don’t be tempted to divide this task into manageable portions, or you may have some prospect of success.
  • Close down everything for several days. If your customers might have to rely on some part of your web services to keep their products working, make sure you close down that part in particular. Let ’em stew.
  • Give the update job to a clumsy intern in your office that has never been allowed near a computer before.
  • Failing that, outsource the job to the lowest bidder. Ideally, have it done in a country that has a first language other than your own, to maximise the potential for misunderstandings.
  • When the user ID merge is done, make sure it is still broken for some people. Have multiple users with the same ID and multiple IDs with the same user. Some people’s existing user IDs will fail, so encourage them to make new ones and then refuse to allow it on the grounds that they already have an ID.
  • Make sure random people’s user IDs work in some places but not others. If they are paying for a maintenance contract, do your best to prevent them from using it.
  • Update your discussion groups to a new format. Of course, you should only do this if your existing groups are fast, efficient and reliable, and nobody is complaining about them. If it ain’t broke, fix it. Fix it real good.
  • If people have actually asked for any new features, such as signatures in their web-based posts, make sure you don’t provide them.
  • Don’t ask for feedback on any suggested changes. Before jumping in with the whole big update, don’t put up a sample discussion group to ensure that it works and that people like it. The slogan “Just Do It” works here, but already belongs to somebody else. Try “Don’t Look Before You Leap” instead.
  • Make sure you expose your customers’ private data to the world so they will never want to trust you again. If you can, make their email addresses visible to the spambots. Leave this visible for at least a week to give the trawlers a chance to do their harvesting, no matter how many impassioned pleas people make. You get bonus points if the exposed email address is also the user’s login ID. Spammers, scammers and phishers will love you, but your customers will not.
  • Make the new discussion group system slow, unreliable, and less efficient to use than before.
  • Ensure the discussion group editor messes up the formatting of people’s posts. Have it insert random junk into the posts and then refuse to let them edit it out. For bonus points, let them edit it out, but then ignore the edits or randomly re-insert new codes.
  • Make sure the search engine doesn’t find anything from before the update. If anybody attempts to change the search settings to find all posts, reward them by making sure it finds nothing at all, not even the recent posts it found a few seconds earlier.
  • If people are likely to post, say, program code, make sure you wrap it all up into one line to render it illegible.
  • If your customers are likely to use certain characters like square brackets in their posts, choose these as special characters in your editor. Mess up people’s posted program code into stuff that looks like a mass of broken links.
  • After a week or so, change your mind about the square brackets thing so that people who used that facility for their links now have posts that make them look like idiots. But don’t completely change your mind about it. Break the display of such links, but still encourage the users to insert them. For bonus points, insert each link at the start of the message rather than where the user expects it to go.
  • Log people off every so often so they have to keep logging on. Provide a “Remember this” feature that doesn’t.
  • If you are silly enough to allow people to keep their old items-per-page settings and you accidentally provide a control panel that works, make up for this by making those old settings unavailable in the control panel. In this way, you will prevent them from using a perfectly functional control panel for fear of losing their settings.
  • People who place attachments in their messages deserve to be frustrated, so you should break that feature for a while. Then allow some files to be attached, but mess up their display and randomly refuse to allow people to get at them.
  • If you think people might want to paste things into their messages, make it as awkward as possible. Copy and paste has universally worked a certain way for decades, so to keep on doing that is just what they will be expecting you to do. Do something new and interesting instead. Force them to go through a slow and arcane multi-stage process to paste the word “and”.
  • Because you don’t have full control over what appears on the screen, it’s much harder to mess up newsreader access, but make sure something makes life intolerable for those people too. Formatting attachments as garbage text is always a useful trick.
  • If you have an excellent educational conference coming up and people have complained about the associated web services in the past, take this opportunity to make them worse.

That’s all I have, sorry. My imagination must be failing, because I can’t think of any other ways a company could mess up such an update. Does anybody else have any other suggestions?

Is AutoCAD becoming more or less productive?

It seems that most of you are convinced that AutoCAD is getting slower, but I’ll leave the poll going for a while longer. But even if AutoCAD is getting slower, does that mean that it’s actually less productive? Do the new features introduced in recent releases allow you to produce more useful work in a given time, despite making you wait from time to time? I’ve added a new poll to see what you think.

In which direction is AutoCAD’s performance going?

I see quite a few comments in various places that say that AutoCAD’s performance has been getting progressively worse by the year. Is this what most people think, or just the viewpoint of a few complainers? Let’s find out, shall we? I’ve added a poll that asks for your opinions. Feel free to comment, too.

Note that this is a poll about raw performance, not productivity. It’s possible (though difficult) to make a program go slower but still allow you to produce more work in a given time, so I’ll cover the productivity angle in a later poll.

This poll is purely about how fast AutoCAD seems to you. How often do you find yourself hesitating, or waiting, or even going for a coffee break, while AutoCAD does its stuff? Is this getting better or worse? If you compare it with an earlier release, does it seem faster or slower? It is to be expected that some things will get faster and some slower, but what’s your overall impression?

AutoCAD 2009 – Video from product managers

I generally dislike blogs that just regurgitate contents from elsewhere, so I’m going against the grain here to repost something from Shaan Hurley’s Between the Lines blog.

Shaan has been a bit quiet over the past few weeks, but has recently made up for this with a vengeance. A flurry of new posts has pushed this video way down the page, so you may well have missed it. I’m always happy to see Autodesk communicating with its customers (even if I don’t agree with what’s being said), so I decided to bring it to your attention.

Here, Autodesk product managers Eric Stover and Doug Cochran show off some of the new features of AutoCAD 2009.

It seems Doug is very keen on the use of the words “quick” and “quickly”. Hopefully, that means we will see some serious attention paid to AutoCAD’s performance soon, because it could certainly do with it.

This video may lack professional gloss, but I don’t care. In fact, I much prefer something that looks like it hasn’t been processed through a PR committee before we’re allowed to see it. I hope we see more communication like this soon from the real people behind the Autodesk corporate facade.

AutoCAD 2009 – Layer Palette and performance

If you’ve noticed some normal drafting operations are much slower in AutoCAD 2009 than in earlier releases, try turning off the new Layer Palette and see if the problem goes away. For example, editing viewports with the Layer Palette visible can be completely unworkable. Don’t just auto-hide it, close it altogether.

Another problem presented by the Layer Palette is that any layer changes you make are applied as you make them. This sounds great in theory, but if each operation takes a while to perform then that’s much less efficient than the old method where all changes are made at once when OK or Apply is picked.

I know a non-modal layer interface was a common wish and it sounded like a cool idea, but now Autodesk has actually been kind enough to grant this wish I’m finding I prefer the old method. I generally don’t need access to all that layer functionality all of the time, so it makes sense to only have the interface occupying that big slab of screen real estate when I actually need it. Your requirements may differ, of course.

If you’re a layer Luddite like me, you can use the old interface by issuing the Classiclayer command. Alternatively, if you set the undocumented system variable LAYERDLGMODE to 0, the Layer command will invoke the old interface instead of the new one.

AutoCAD 2009 – The Prequel Part 17 – Ribbon Performance 2

Testing performance under Vista can be an interesting experience. The trouble is, Vista tries to improve its performance by observing what you do and caching it for later use in case you do it again. This leads to something akin to the observer effect in science, where the very act of observing something has an effect on what it is you are observing.

Every time I test Ribbon tab switching performance in Vista, the results improve. In XP, the worst tab switching time I saw on my Core2 PC was 1.6 seconds for the first exposure of the Tools tab. In Vista, the same thing took 1.2 seconds the first time I tried it, but subsequent attempts (after closing and restarting AutoCAD but not rebooting) gave results in the 0.5 to 0.6 second range.

I tried turning off Vista’s pretty Aero interface and saw improvements of about 0.1 seconds in every measurement. With Aero off and testing a second time, I saw first tab switches from 0.2 to 0.6 seconds and second tab switches between 0.3 and 0.5 seconds. Most switches were around the 0.3 second mark.

While I hesitate to base any firm conclusions on such shaky ground as these rather unscientific tests, I can say this with some confidence: it is possible to have a system running AutoCAD 2009 under Vista where the Ribbon tab switching performance meets in most cases, and is close to meeting in all cases, the 0.3 second mark that most users perceive as instant response. However, your mileage may vary. Correction: your mileage will vary.

AutoCAD 2009 – The Prequel Part 16 – Ribbon Performance 1

One of the things I like least about AutoCAD 2009 (at least in Release Candidate form) is that I find it very “sticky”. That is, I find myself having to wait for an instant here, then again there, yet again over there. Most of my testing has been on a middle-aged Pentium 4 (3.0 GHz dual core – not too ancient), and it is particularly noticeable there. On my newer Core2 machine, things are better.

When AutoCAD 2009 starts shipping, I suspect your perception of it will be strongly influenced by your hardware. Top gun users on slow machines are going to feel frustrated; slower users on fast machines will wonder what the problem is.

I made a video that shows Ribbon tab switching performance. This is an important aspect of the new interface. Because the Ribbon hides tools behind different tabs, quick access to those tools relies on near-instant tab switching. How well does AutoCAD 2009 do at that? Let’s have a look on a fairly quick PC (Core2Duo E6600 with 4 GB RAM, under Windows XP SP2 32 bit). I intend to do the same in Vista later.

Ribbon tab switching performance in XP

Measured on a faster machine and viewed objectively, it looks rather better than my perceptions from the slower machine had led me to believe. The real problem is the first exposure of each tab, because after that the tab contents can be retrieved from cached memory. The Tools tab is tardiest; 1.6 seconds here translates to 3 seconds or more on an older PC. For the most part, the tab switching speed is acceptable after the tab has been exposed for the first time. For most users, a delay of 0.3 seconds between input and response is quick enough to be considered instant, and most tabs switch in a time fairly close to that after the first exposure.

One way of avoiding or reducing tab switching frustration is to make your own custom Ribbon with a home tab full of the things you use most of the time. How easy is that? Unfortunately, it’s not. Using CUI to make Ribbon parts is not a pleasant experience. That interface makes the Ribbon look super-snappy in comparison. The Ribbon’s more complex internal structure combines with CUI’s snail-like performance, bugs, restrictions and design errors both old and new, to make custom Ribbon creation a loathsome task.

AutoCAD 2009 – The Prequel Part 13 – ViewCube

For many 3D users of AutoCAD, the ViewCube is likely to be the most useful new thing in AutoCAD 2009. There are a couple of problems with it, at least in the Release Candidate:

  1. It does not work in 2D wireframe mode (which is, paradoxically, where 90% of my 3D work is done). You need to choose another visual style before it will appear.
  2. It seems to slow things down quite a lot in complex drawings.

That said, if you have more than enough computing power for the drawings you usually deal with, then this is a very, very nice interface addition. You can just pick intuitively on the various parts of the ViewCube and your view of the model changes accordingly. You can also click and drag on the cube, and it will move where you place it, while snapping on to the various 45 and 90 degree view directions when you get near them, in the same way that Polar snap works. There is a right-click menu with a bunch of useful options, including a quick and easy switch between parallel and perspective views.

Messing with the ViewCube

You can also easily switch between User Coordinate Systems using the little menu thing under the cube. Unlike some of AutoCAD 2009’s new user interface elements, the ViewCube looks like a finished, polished tool and provides a genuine boost to productivity. Beautiful.

AutoCAD 2009 – The Prequel Part 8 – Vista Startup Times

I’ve now tested startup times of various AutoCAD releases under Vista. Here are the results, alongside the XP results for ease of comparison:

Release First
Startup
Subsequent
Startup
XP Vista XP Vista
12 8.6 8.2
13 2.6 1.8 1.3 0.8
14 2.1 0.5
2002 3.2 2.1 0.6 1.1
2004 4.3 1.7
2005 7.9 4.5
2006 14.9 8.7 2.6 4.4
2007 13.8 11.9 3.5 6.6
2008 14.6 10.5 3.6 6.0
2009 28.9 17.3 7.2 13.3

Same caveats as before, plus the following:

  1. Some AutoCAD releases were not installed on both XP and Vista partitions, hence the gaps in the table.
  2. The Vista tests were performed on the same PC as the XP tests.
  3. The system had a 1 GB USB key hanging out the back, giving Vista a theoretical startup benefit over XP.
  4. It’s very difficult to get meaningful performance results out of Vista because its SmartFetch and ReadyBoost technologies are doing their best to improve performance without user intervention. I may be a geek, but I’m not a good enough geek to be able to tell what Vista was doing behind my back during these tests.
  5. Repeated startups of AutoCAD 2009 revealed a gradual improvement in startup performance. Startup times went 17.3, 13.3, 12.5, 12.5, 11.0 seconds.

Make of that what you will. In short, in my tests AutoCAD 2009 startup time in Vista is still roughly double that of its recent predecessors and about ten times longer than older releases like R13 and 2002.

AutoCAD 2009 – The Prequel Part 7 – Subsequent Startup Time

This table shows both the initial and subsequent startup times for various releases. Most of the qualifications and caveats from my AutoCAD 2009 – The Prequel Part 6 – Initial Startup Time post still apply here.

Release First
Startup
Subsequent
Startup
12 8.6 8.2
13 2.6 1.3
14 2.1 0.5
2002 3.2 0.6
2006 14.9 2.6
2007 13.8 3.5
2008 14.6 3.6
2009 28.9 7.2

AutoCAD 2009’s subsequent startups are much less slow than its agonising first startup, as to be expected. Windows XP is doing that by caching and reusing recently used parts of memory. Release 12’s old code, running in 16-bit emulation, is not able to take advantage of that. It’s definitely an unfair test of Release 12 on this system.

In my tests, AutoCAD 2009 startups (both initial and subsequent) are about twice as slow as other recent releases. Users of older releases on modern systems can enjoy startup performance over ten times better.

AutoCAD 2009 – The Prequel Part 6 – First Startup Time

One thing you’ll notice (and dislike) right away with AutoCAD 2009 is that it takes a lot longer to get started. How much longer? About twice as long as recent releases, or about ten times longer than ancient speed demon Release 13. (I bet a 1994 AutoCAD user transported forward in time would be shocked to hear that description being used). Here’s a video that shows what the first startup looks like in a collection of releases from Release 12 to 2009:

AutoCAD First Startup Time Comparison

Now for the qualifications and caveats:

  1. Tests performed on a Core2Duo E6600 PC with 4 GB RAM, under Windows XP SP2 32 bit.
  2. This is not a strictly scientific comparison. Only one system restart and settle-down period was performed prior to timing all releases one after the other. Strictly, each test should get its own restart and settle-down period.
  3. Anti-virus and other security software was left on, but was not performing a scan, during the tests.
  4. This is the first startup time only. Subsequent startup times during the same Windows session are quicker, and this subject may be the subject of further coverage.
  5. Vista startup times may be better, particularly if you leave a spare USB key hanging out of your PC and allow Vista to use it to improve system performance. This may also be the subject of further coverage.
  6. The AutoCAD 2009 time is for the Release Candidate, not the shipping product. It’s possible that Autodesk managed to wring more performance out of 2009 before the code hit the manufacturing stage.
  7. Application startup time should not be used as an indication of overall performance. It’s just one aspect of it.

If you only start AutoCAD once a day, it’s not a significant issue. If, like me, you start AutoCAD dozens of times a day, it becomes rather wearing.
