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 be loaded, as with AutoCAD. Even OpenDCL is supported. It’s a quite astonishingly high level of compatibility.
But it’s not 100%. There are minor incompatibilities, system variable and command-line differences that cause problems in a handful of cases. It’s often possible to work around these and still retain … Full post
A frequently stated advantage of CAD on the Cloud is the access to large amounts of processing power. Instead of relying on your lowly local processor to perform complex tasks, you can instead zap the job up to the Cloud where vast numbers of processors churn away in massively parallel fashion and then zap the results back to you before you’ve even had time to head for the coffee machine.
This is a scenario that applies only for certain types of very complex tasks that are suited to subdividing the calculations among many processors. Autodesk already has a big toe in the waters in several of those areas. The recent Autodesk Cloud changes made available Inventor Optimization, Cloud Rendering, Green Building Studio and Conceptual Energy Analysis to a small subset of Subscription customers. It’s safe to assume that these services will be improved and expanded over the next few years. (Is there … Full post
Heidi Hewett just reported the following on her blog, about a productivity study:
According to a recent independent study, AutoCAD® 2011 can help you work up to 44% faster with the latest productivity enhancements.
I have a couple of problems with that sentence. First, it’s not an independent study. It’s a study conducted by long-time respected CAD figure David Cohn, but it was specified and paid for by Autodesk:
This productivity study was performed at the request of Autodesk Inc., which funded this work.
That’s not exactly independent then, is it? Second, the study does not state that AutoCAD 2011 is responsible for a 44% improvement. That’s a figure that combines both the effects of AutoCAD 2011 (over AutoCAD 2008), plus the effects of using a newer, faster PC. Just stating that figure wthout such a disclaimer is misleading.
Now to the study itself. Let me make … Full post
With all this talk of clouds in the air, it is interesting to note that Autodesk has moved AutoCAD’s Help system to a browser-based format, with online access as the default. So, how has Autodesk done with this first dipping of its toes into the cloudy waters with its primary mainstream product? I’ve already had a couple of unsolicited comments on the subject, and I’d like to hear from you. How do you rate the following, compared with previous releases?
- Performance (online)
- Performance (offline)
- Search results
- Content completeness and accuracy
- Ease of manual browsing
- Efficiency of user interface
- Concept of online Help
- Anything else you want to mention
Please comment to express your views and use the poll on the right to provide an overall rating of the new system.
A problem I’ve seen affecting keyboard users (particularly fast ones) in recent AutoCADs (since 2006) is that the characters entered into the command line are not always the ones you typed. Or rather, they are the ones you typed, just not in the right order. In particular, I’ve seen the first couple of characters get messed up, so you might get ILNE instead of LINE. In addition to the annoyance factor, this is something of a productivity killer.
Has this happened to you? If so, please comment. Any comment is welcome, but it would be great if you could provide the following information:
AutoCAD (or vertical) release(s) where you have seen this happen. Also mention any recent releases where you have seen it not happen.
Command line status when you have seen this happen (docked, floating, off, all of the above).
Dynamic input status when you have seen this happen (on, … Full post
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.
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 … Full post
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.
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? … Full post
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 … Full post
You have undoubtedly noticed the large red A in the top right corner of the AutoCAD window. Personally, I don’t like the look of it. The concept is rather Fisher-Price and the execution is poor. No competent graphic designer would align the top of the red A exactly with the top of its surrounding button area like this:
There are so many examples of poor graphic design in AutoCAD 2009 that the overall visual effect is close to that of a rather amateurish shareware product. That’s not what you might expect of a multi-billion dollar company that can undoubtedly afford to pay talented people to do much better, but it’s a relatively trivial matter. You probably want to know how it works, rather than what it looks like.
What’s living under that big red A? It’s called the Menu Browser, and it’s … Full post
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 … Full post
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 … Full post
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:
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.
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 … Full post
Dude, Dashboard’s dead. Defunct. Done. AutoCAD 2009 replaced the Dashboard with the Ribbon. If you type in the DASHBOARD or DASHBOARDCLOSE commands, they are just converted to the RIBBON and RIBBONCLOSE commands, which turn the Ribbon on and off.
If you’re a fan of the Dashboard (and I never was), there is good and bad news. The good news is that you can right-click on various parts of the Ribbon, pick Undock and you get a Dashboard-like floating vertical Ribbon that can be resized and configured very easily in terms of turning panels on and off. You can’t do that with Microsoft’s Office 2007 Ribbon. Performance aside (more on that later), I generally prefer the way the vertical Ribbon works, compared with the Dashboard. But I’m still not a fan.
The bad news is that if you put a lot of effort … Full post
I’ve now tested startup times of various AutoCAD releases under Vista. Here are the results, alongside the XP results for ease of comparison:
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:
Some AutoCAD releases were not installed on both XP and Vista partitions, hence the gaps in the table.
The Vista tests were performed on the same PC as the XP tests.
The system had a 1 GB USB key hanging out the back, giving Vista a theoretical startup benefit over XP.
It’s very difficult to get meaningful … Full post
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.
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 … Full post
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:
Now for the qualifications and caveats:
Tests performed on a Core2Duo E6600 PC with 4 GB RAM, under Windows XP SP2 32 bit.
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.
