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 – Tooltips are bad for my sanity

In the general scheme of things, this is a relatively trivial issue, but it’s sometimes the little things that get under my skin. Winner of this year’s prize for most annoying new feature just has to be the new tooltips. They are really not good for my mental health. If I have tooltips turned on, I find it hard to use AutoCAD 2009 for more than a few minutes without wanting to smash my fist through the screen.

I would like to leave tooltips on just a little bit so they will let me get used to AutoCAD’s modified button appearance and location. All I want is a little one-word tooltip if I hover over a button, but I can’t have that. There is some control over tooltips to be had in the Options dialogue box:

Controlling tooltips in Options

Oh, sorry, you can’t see the options I’m trying to describe because there is a stupid great big tooltip in the way. What I’m trying to show is that if you turn off all but one of the toggles, you can at least avoid the embarrassing spectacle of AutoCAD covering up most of the screen with information about how to draw a line when you hover over the Line button. But you can’t persuade AutoCAD to just show you what the commands are, you have to have several lines of information, one of which is exactly the same for every single tooltip.

The least intrusive tooltip available

That’s not too bad I suppose, but try using a dialogue box. Nasty huge tooltips keep throwing themselves at you in a mad rush to obscure what you’re trying to see. You can move your cursor right out of the way to stop the tooltips from appearing, and then move it back again when you want to actually pick something, but what a waste of time, mental energy and wrist effort.

You didn't want to see what's under here

OK, so you’ve had enough of them? Want them all banished? Fine, back into Options, turn that last toggle off, pick OK (assuming it’s not obscured by a tooltip so you can see it) and you’re done. Or are you? Back into Options, pick the Files tab and do a bit of hovering.

Even when they are off they are on

Aaaagh! The stupid tooltip isn’t even accurate. It doesn’t describe what you’re hovering over, it describes the files category that’s selected, which could be off the screen. If nothing is selected, it describes the first category rather than what you’re hovering over. Duh.

OK, Autodesk people, own up. Who thought this was a good idea? Really, what on earth were you thinking?

AutoCAD 2009 – ViewCube problems?

Having been very effusive in my praise of AutoCAD 2009’s ViewCube feature, stating among other things that “the ViewCube looks like a finished, polished tool”, I may need to backpedal. Those views, along with all of my 2009 Prequel posts, were based on my experience with the Release Candidate.  Although ViewCube was very stable for me in pre-release versions of 2009, I’ve seen severe ViewCube stability problems in the shipping software.

I’ve seen the following problems in just a few minutes use of the ViewCube, on two different PCs:

  • Picking the WCS button under the ViewCube and then picking a different visual style led to AutoCAD going into an endless loop where it kept flashing up and removing the WCS menu about twice a second. Ctrl-Alt-Del was needed to get out of this. This lock-up could be repeated by using the UCS button and picking in the drawing area to make the UCS menu go away.
  • In my attempts to reproduce this on another PC I couldn’t immediately do so, but by using the Home feature and changing visual styles I could make my cursor disappear so it looks like AutoCAD is locked up. No cursor was visible anywhere within the AutoCAD window (including crosshairs, pickbox and arrows), but the normal Windows cursor was visible outside AutoCAD. I could use the invisible AutoCAD cursor to highlight buttons and could therefore close AutoCAD without losing anything.

So, if you are using the shipping version of AutoCAD 2009, I suggest you save all drawings in your session before experimenting with the ViewCube. I would be interested in your experiences with the ViewCube. Is it reliable for you?

AutoCAD 2009 – Automatic spell checker

I’ve seen quite a few positive comments about the new automated spell checking feature, with some people saying that it alone is enough to make AutoCAD 2009 worth the price of admission. I wouldn’t go quite that far, but it is a nice feature. If you enter or edit text or mtext, a little dashed red line appears under words that are not in the dictionary. Right click on an unknown word and the menu will offer several suggestions, allow you to ignore the word or add it to the dictionary.

It does have limitations, though, such as not working with attributes. Don’t expect it to do the things that Word does, such as auto-correct words or check your grammar. There is nothing to inform you that you have used a valid word in the wrong context, so AutoCAD considers this to be a perfectly valid sentence:

Eye cant under stand how any one cud sell any off they’re worms rung wen awl 0f there worlds ate testes width a auto mated shell checked.

Translation:

I can’t understand how anyone could spell any of their words wrong when all of their words are tested with an automated spell checker.

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 – Action Recorder needs action

One of the banes of AutoCAD over the past few years is the phenomenon of the half-baked feature. A new feature is added to the product with serious design deficiencies and/or bugs and other shortcomings that make it much less useful than it should have been. I’m sure you have your own favourite examples of this. I may expand on this theme in future, but for now let’s concentrate on one brand new and particularly undercooked feature, the Action Recorder.

The ability to record and play back macros is undoubtedly something that many users want, and has featured prominently in some wishlists. Autodesk has now provided the Action Recorder. Wish granted, right? A shining example of Autodesk listening to its customers and providing what they want and need? Not exactly. In fact, this wish has only been granted at the most superficial level.

Here is the wish as seen on the 2003 AUGI Top Ten AutoCAD Wish List (it’s number 6): “Provide a VBA Macro recorder.” Here it is as it appeared in the February 2006 AUGI Wishlist (it’s number 1): “The ability to record the process of a certain task and assign a quick key to it – similar to Microsoft’s macro recorder for office products.”

People were asking for something similar to what they had in Microsoft products. That is, something that not only allows actions to be recorded and played back, but to also create some kind of editable programming language code. Why would people want that? Because recorded macros can be easily examined, modified, combined, changed from one-off to repeating sequences, used as the basis for slightly different routines without requiring re-recording, incorporated into full-blown routines, and so on. The need for editable code is blindingly obvious, really.

So, how does Action Recorder store its macros? As VBA code? No, but that’s not surprising because Microsoft has dictated that VBA is doomed. LISP code, then? No, LISP is unfashionable at Autodesk. Script files? Nope. XML? Try again. It’s a new and proprietary format. It’s binary, not text. It’s undocumented. There is no known access to the code via AutoCAD’s other programming interfaces. In summary, it’s a closed format.

Does that matter if you can edit it using Autodesk’s tools? Yes it does, but in any case you can’t edit it in any meaningful sense. The only editing mechanism provided by Autodesk is the Action Tree, and it’s woeful. Pretty much the only things you can do with it are to delete whole commands and to change certain recorded actions to prompt for user input instead. You want to change a macro to set up certain layers before you start? Sorry. You want to add a command to the end of a macro? Nope. You’ve picked 3 times during a command and you want to change it to 2 or 4 times instead? Too bad. You want to use one macro as the basis for a whole series of macros, just changing a couple of things from macro to macro? No can do.

This lack of a useful editor isn’t just a problem for CAD Managers and power users. If anything, it’s even more of a hindrance for the novice users it’s obviously aimed at. Who is more likely to get an extended command sequence wrong? A power user with years of experience writing menu macros, or a new user? So who is most likely to need to fix up their macros after recording?

There are various other things wrong with the Action Recorder that go to make it a very frustrating tool. The way in which points with object snaps are recorded is unusable. The way in which zooms occur is bound to cause lots of surprises. The inability to record dialogue box operations is going to confuse and frustrate many users. The habit of the Action Tree in always pinning itself in place is annoying. Its inability to resize outside a very limited range is restrictive. The plethora of in-your-face warnings will have you groaning more than Vista’s User Access Control, and don’t think of turning them off in advance, that’s not allowed. Finally, if you’re not a Ribbon user, forget it. While the command line interface allows for recording and playing back macros, there is no way of editing them. So unless you want to do exactly the same thing in exactly the same location in all your drawings, you’re out of luck.

Don’t take my word for it, try it for yourself. Try to make a macro that does something simple but useful like rotating a piece of text about its insertion point, or inserting a block on a line and then trimming the line within the block. By the time you’ve worked out that it can’t be done, you could have learned about menu macros from scratch and written something that actually works, several times over. A word of warning; please make sure you lock up any pets or children before starting this experiment.

The Action Recorder is a “brochure feature” only; it serves as a marketing tool for Autodesk rather than a genuinely useful productivity tool for its customers. This wouldn’t be so bad if it was an isolated case, but it isn’t. Unfortunately, half-baked new features are now the rule rather than the exception.

Why is this so? Is Autodesk cynically trying to fool its customers in an evil revenue grab? Does the AutoCAD development team spend its time trying to come up with deliberately half-baked features? No. The developers don’t want to make these weak and useless things; they are human beings with the same urge as the rest of us to do well and be proud of their work. The problem is that there is simply not enough time to do a good job with a major feature and finish it off. It all comes down to the 12-month release cycle; it just isn’t working.

AutoCAD 2009 – A new release is on the cards

When AutoCAD 2009 arrives, what exactly do you get? Inside the brown cardboard box is a fatter DVD case containing one DVD and a set of cards describing the new features:

AutoCAD 2009 Packaging

I haven’t discovered the rules yet; maybe they are in Help somewhere. Is Menu Browser worth more than ViewCube? Does Action Recorder trump Quick Properties? Is DWFx a wildcard? Inquiring minds want to know.

DWG TrueView 2009 – it measures!

Autodesk’s DWG viewer history has been one of twists and turns, including name changes, attempts to charge money for it, lost features, bloat, and general confusion. One of the most obvious problems that prevented people using the recent DWG TrueView offerings was the inability to measure objects. As a result, some people who needed a DWG viewer turned to the MicroStation-based offering, Bentley View. It took a while, but that omission has now been remedied and Autodesk now provides a useful tool for non-AutoCAD users who need to check drawings. You can download it here:

http://www.autodesk.com/dwgtrueview

It’s a 194 MB download in 32-bit form, so it’s no lightweight. It is basically a very cut-down AutoCAD 2009 and shares its Ribbon interface, albeit in much simplified form.

AutoCAD 2009 – Putting things back to “normal”

Note: there are updated versions of this post for AutoCAD 2010, 2011 and 2012. If you’re running a more recent release of AutoCAD, have a look at the post AutoCAD 2017 – Putting things back to “normal” instead.

One thing that’s regularly asked whenever a new AutoCAD release hits the streets is how to make it work like the last release. I think you should give any new features a fighting chance before turning them off or ignoring them, but that’s entirely your choice. Let’s assume you’ve made the decision to go back to the future; how do you do it?

  • Menus and Ribbon. You can turn menus on with MENUBAR 1, close the Ribbon with RIBBONCLOSE, and so on. However, there’s an easier way; just switch workspaces. In the bottom right corner there is a little button that looks like a gearwheel. This is the Workspace control. Click on it and pick the item called AutoCAD Classic.
  • Dashboard. The Dashboard is gone, but you can have a vertical Ribbon instead. If the Ribbon is not visible (it won’t be if you just selected the AutoCAD Classic workspace), enter RIBBON to bring it back. In the tab title row (the bar with the word Home in it), right-click and pick Undock. Now you can place and size your Dashboard-like thing as you see fit. As before, you can right-click on things to change the various settings. However, getting the contents exactly the way you want it usually involves using CUI, and that’s well outside the scope of this post.
  • Background. Many of you will want a black background, of course. Right-click on the drawing area and pick Options…, then pick the Display tab. Don’t be tempted to choose Color Scheme and set it to Dark, because that just changes the appearance of various user interface elements. Instead, pick the Colors… button. On the left, choose a context you want to change (e.g. 2D model space), choose the appropriate background element (e.g. Uniform background) and choose the particular shade that takes your fancy. There is a Restore Classic Colors button, but that only takes you back to AutoCAD 2008. When you’re done, pick Apply & Close, then OK.
  • Status bar. Right-click on a status bar button, turn off Use Icons and your text-based status bar buttons will return.
  • Classic commands. If you prefer not to leave the various new palettes on screen all the time, old versions of various commands are still available: ClassicLayer, ClassicXref and ClassicImage. Going back further, there are command-line methods of doing the same thing: -Layer, -Xref, XAttach, -Image and ImageAttach.

If you’ve allowed AutoCAD to migrate your settings (I never do), some of the above will already be done for you, but by no means all of it.

One of the great things about AutoCAD is that we can still do this sort of thing. Microsoft has a lot to learn from Autodesk in this regard. If you’re using Word 2007, you are going to have a Ribbon and that’s the end of it, so be a good little user and learn to love it. Oh, and don’t even think about trying to modify it. Whatever you might think about Autodesk’s development priorities, design decisions and feature implementation, at least in most cases Autodesk leaves us with a choice.

AutoCAD 2009 – The Reaction Part 1

Some people have now received AutoCAD 2009, or at least downloaded it, which you can do (legally!) here, as long as you’re in the United States or Canada.

I’m closing the AutoCAD 2009 speculation poll. Other than a small blip on “Very bad”, the poll follows a typical bell curve nicely, with the peak very clearly on “OK”. I will poll on AutoCAD 2009 later, once you’ve had a chance to play with the new product.

What is the initial user reaction like? So far, not good. For example, have a look at Autodesk’s AutoCAD 2009 discussion group. I fully expected an initial adverse reaction to the new user interface, but it will be interesting to see if it persists once the shock of the new has worn off.

AutoCAD 2009 – The Prequels Are Over

It would appear that AutoCAD 2009 is now shipping. I intend to hold off on any further comments until I get my hands on the shipping product, which I expect to be fairly soon. In the meantime, maybe have a look over the 24 AutoCAD 2009 Prequel posts and see if there’s anything you missed.

If there’s something in particular about AutoCAD 2009 you want clarified or would like to see covered in future posts, feel free to add a comment here or email me.

AutoCAD 2009 – The Prequel Part 24 – Menu Browser Keyboard Access

You may be used to accessing pull-down menus with Alt-key combinations, e.g. Alt+F to get at the File menu. You can still use those keystrokes to get at menus in AutoCAD 2009, whether or not the pull-down menus are in place. If the pull-downs are visible (MENUBAR=1), they are given priority over the Menu Browser. One difference is that if the pull-down menus are visible, you can either press the keys together (e.g. Alt+F), or you can press and release the Alt key, then choose the menu (e.g. Alt, F). With the pull-down menus turned off, you can use only the former method; just pressing and releasing the Alt key is ignored.

Here is a list of the Alt-key combinations that will work with either the pull-down menus or the Menu Browser:

Keystroke

Action

Alt+F File menu
Alt+E Edit menu
Alt+V View menu
Alt+I Insert menu
Alt+O Format menu
Alt+T Tools menu
Alt+D Draw menu
Alt+N Dimension  menu
Alt+M Modify menu
Alt+W Window menu
Alt+X Express menu
Alt+H Help menu

Of course, the above only applies in the standard AutoCAD environment. In a custom environment, things could be quite different.

The following key combinations apply only to the Menu Browser. Unfortunately, they are ignored if the pull-down menus are visible:

Keystroke

Action

Alt+R Recent Documents
Alt+C Open Documents
Alt+A Recent Actions
Alt+S Open Menu Browser with focus on Search

The last combination can be used as a prelude to searching the menus, or simply as a way of exposing the Menu Browser without having to click on the red A.

AutoCAD 2009 – The Prequel Part 23 – Recent Actions

Like Recent Documents, the Menu Browser pane also stores a Recent Actions list.

AutoCAD 2009 Recent Actions list

  • Like Recent Documents, the length of this list defaults to 9 and can be set to up to 50 in Options.
  • Similarly, you can pin actions in place to prevent them slipping off the end.
  • Unlike the command line recall (up-arrow) method of retrieving recently entered commands, this feature only remembers commands you selected using the Menu Browser. Even if you use pull-down menus, those commands will not be placed in this list.
  • Also unlike command line recall, the list is remembered between drawing sessions and even AutoCAD sessions (i.e. you can close AutoCAD without losing the list)

AutoCAD 2009 – The Prequel Part 22 – Open Documents

One more feature that’s crammed into the Menu Browser pane’s limited space is the Open Documents list. This allows you to switch between the drawings you currently have open. It has a similar interface to the Recent Documents list, including the persistently pale preview:

AutoCAD 2009 Open Documents

Unlike Recent Documents, the filenames are displayed in the correct case, although this is not true in the preview where the name and path are all in upper case. Another glitch in the preview can be seen above, where it says Currently Oper instead of Currently Open By:. This only happens intermittently and doesn’t concern me greatly.

In the same way that Recent Documents doesn’t eliminate the equivalent feature in the File pull-down menu, Open Documents doesn’t eliminate the equivalent feature in the Window pull-down menu. Note that this applies only to the traditional pull-down menus you get if you set MENUBAR to 1; the File and Window menus in the Menu Browser are missing the lists of documents.

If you want to switch between open documents quickly without looking under the red A, the Ctrl+Tab and Ctrl+Shift+Tab keyboard combinations still work in AutoCAD 2009, as they have ever since the multiple document interface was introduced by AutoCAD 2000.

AutoCAD 2009 – The Prequel Part 21 – Recent Documents

Another thing you will find lurking under the big red A is the Recent Document list. This is a mixed bag too, but most of it is good. It differs from the traditional list that still lives under the File menu in several ways:

  • Although the default maximum list length is 9 items, you can allow up to 50 items into the list by changing a setting in the Options command’s Open and Save tab.
  • If the list exceeds the space available, a scroll bar appears. This has the same problems as elsewhere in the menu browser: more clicks are required and there is no auto-scroll.
  • If you hover over a document in the list, it displays a preview image along with some other useful document information. Unfortunately, that preview image always has a white background, despite the fact that the first thing most of you are going to do in AutoCAD 2009 is turn the background black.

Menu Browser Document History

  • The file and path names are ALL DISPLAYED AS UPPER CASE, NO MATTER WHAT CASE THE NAMES ACTUALLY USE. THIS HARMS READABILITY AND MAKES THE WORST POSSIBLE USE OF THE LIMITED SPACE AVAILABLE. SORRY, AM I SHOUTING? Is that better?
  • Using the cute little push pins at the right of each document name, you can pin documents in place to prevent them being pushed off the end of the list.
  • You can change the order in which the documents are displayed using this menu:

Menu Browser Document History

  • You can also change how the documents display using this menu:

Menu Browser Document History

Using the last three features together, your document list could end up looking something like this:

Menu Browser Document History

AutoCAD 2009 – The Prequel Part 20 – Menu Browser Search

So if the Menu Browser isn’t much use for browsing menus, what is it good for? Searching menus, for one thing. Let’s say you’re a very occasional 3D user trying to make a 3D model look pretty. You want to access commands for placing lights, putting the sun in the right place, and changing visual style settings. You don’t really know where to look in the Ribbon or menus. What to do? Click on the red A and just start typing what you think the command is called. With a bit of luck, the appropriate menu item will present itself and you can click on it.

This video shows three successful Menu Browser searches by typing in “light”, “sun” and “vis”.

Searching using the Menu Browser

The whole thing is over in 14 seconds. That’s quite impressive in comparison to a manual click-and-hunt search. It’s not foolproof, though. It’s a menu search, not a command search. That means the command you’re after has to be in the menus before it can be found. If you type in something like “osnap” or “oops” you’ll be out of luck, even though they are both valid AutoCAD commands.

AutoCAD 2009 – The Prequel Part 19 – Menu Browser

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:

The Big Red A

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 a mixed bag. There’s some useful new stuff under there, which I’ll cover later. In this post I’ll just describe using it to browse menus. Frankly, it’s not very good at that. The video below shows you why, and here are some notes to go with it.

  • On a fast machine, the reaction times are slightly sticky. Users of slower machines will experience some frustration; I have waited over three seconds for a reaction. Just like the Ribbon, it’s the initial click that hurts the most, with subsequent clicks on the red A being rather quicker.
  • Because the menu structure is one level deeper than traditional pull-down menus, you need a minimum of one extra click to do anything.
  • Because the Menu Browser is artificially limited to a small section of the screen (no, you can’t resize it), the menus don’t all fit. That means you not only need to perform extra actions to select certain commands, you need to perform extra actions to even see them. That is, if you’re browsing the menus, this new interface is markedly inferior to the old one.
  • With pull-down menus, you need a click to start with, then you can hover (or optionally click) to burrow down until you get to the command you’re after. In the Menu Browser, you need a click, then a hover (or optional click), then it’s all clicks from then on. That is, it’s close to the exact opposite of what you might expect, it’s not even self-consistent, and there is more clicking required than before.

Menu Browser - not so good for browsing menus

If you regularly use pull-down menus, you may as well type MENUBAR 1 as soon as you install your new AutoCAD. You will lose a strip of screen real estate, but you will have your old menus back.

If it’s an unhappy experience using the Menu Browser to browse menus, what else can you use it for? Among other things, you can use it to search menus. More on that later.

AutoCAD 2009 – The Prequel Part 18 – Another Interface Option

There’s one screen-based user interface mechanism in AutoCAD 2009 that you probably won’t see bragged about in Autodesk marketing materials. That’s a shame, because it has some strong points:

  • It can be docked on the side of the screen or allowed to float free.
  • While floating, it can be resized to the desired width and height.
  • If you do dock it on the side, any unused height can be used to place either docked or floating toolbars.
  • Out of the box, it provides access to a large number of the most commonly used AutoCAD commands.
  • In default form, it is context-sensitive, providing you with the options relevant to the command you’re using.
  • It can be modified (using CUI, unfortunately) to provide access to any commands or macros you like, using a tree or sequential structure as you see fit.
  • The interface reacts more quickly to user input than the Ribbon or Menu Browser.
  • Rather than cryptic graphics, it uses plain text labels that are easily understood. This is particularly useful if you have a block library where part numbers are used to identify parts that are visibly similar to each other.
  • It provides an interface that users of old AutoCAD releases will be instantly at home with, and I mean old.

Have you guessed yet?

AutoCAD 2009 Screen Menu

I seem to remember first hearing about the imminent demise of Screen Menus around the Release 12 timeframe. I wonder how long they can survive into the 21st century?

Autodesk deserves credit for keeping stuff like this going after all this time, a long time after it has gone seriously out of fashion. I’m sure the amount of resources it consumes is minuscule compared with the more modern interface elements. I know there are still some people who have a use for screen menus, and the same applies to image menus. All the tablet stuff is still there too, although I haven’t tested it.

Seriously, I’m more impressed by Autodesk’s retention of the Screen Menu than I am by the introduction of, say, the Steering Wheel. Autodesk is unlikely to brag about it, but maybe it should.

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.
