AutoCAD 2012 – How to “hatch” using any objects

Here’s a trick you can use in AutoCAD 2012 to fill an area with any objects you like. It’s not actually hatching, but it has several advantages over the real thing:

  • You aren’t restricted to straight line segments as you are with real hatching. Circles, splines, even solid objects, you name it, you can use it.
  • To define the pattern, you don’t have to master an arcane file format or use trigonometry to work out the numbers used in it. Just draw the objects you want repeated.
  • You can easily change the spacing between the objects later, or even change the objects themselves.

How is this done? Use the new associative array feature, then use XClip to restrict the displayed objects to within a specified boundary. For example, let’s say you have a polyline you want filled with green spheres, and a green sphere already drawn. The sequence … Full post

How to make Ctrl+C perform a Cancel

In a recent comment, I was asked how to make Ctrl+C perform a Cancel. Before I get onto that, here’s a bit of history.

Back in the Dark Ages of DOS, the way to cancel a command was by holding down Ctrl and pressing C. The last release to work like this by default was Release 13 for DOS, released in 1994. I remember the bother it caused my users who were faced with the Windows version in which Esc was used to cancel things and Ctrl+C copied objects to the clipboard. It took me at least a year before I had totally removed Ctrl+C = Cancel from my muscle memory.

Until AutoCAD 2005, Autodesk provided an easy option to keep things the way they were by turning off the toggle Options > User Preferences > Windows standard accelerator keys. In recent AutoCAD releases, you have still been able … Full post

Installation tip – save time and space

If you download AutoCAD or other Autodesk products from either the trial or Subscription sites, the executable you get (e.g. AutoCAD_2012_English_Win_32bit.exe) is actually a self-extracting archive rather than a real installer. When you run it, you are prompted for a destination folder, with a default location such as this:

C:\Autodesk\AutoCAD_2012_English_Win_32bit

The actual installer (setup.exe) and all of the files it needs are then unzipped and placed in a folder structure in that location. When the extraction is finished, the self-extracting executable automatically runs setup.exe and the installation proper can begin. Once the installation is complete, the extracted files are left in place.

You can take advantage of this simple knowledge in various ways:

  • Sometimes, you may you need to run the installer more than once on the same PC. For example, you might need to uninstall/reinstall AutoCAD, or you might be a CAD Manager who installs AutoCAD for on your … Full post

3DConnexion device support in AutoCAD

Do you have a 3DConnexion device (3D ‘mouse’) and use it in AutoCAD or AutoCAD-based products? What do you think of the way it works in the most recent releases of AutoCAD?

From AutoCAD 2011 on, Autodesk provided built-in support for these devices. Has that made things better or worse than in earlier releases? If you’re having problems, exactly what are they and how does it affect your ability to work with AutoCAD in 3D? Is the 2012 support any better than 2011? How does AutoCAD’s support for these devices compare with that of other products?

AutoCAD 2012 – Autoloader mechanism for plug-ins

One of the less obvious features introduced by AutoCAD 2012 is the Autoloader mechanism that has been provided to make installation of plug-ins (current standard Autodeskspeak for add-ons, apps, utilities, routines, etc.) easier for both developers and users. It may not be immediately obvious, but it’s a useful and important addition.

This mechanism has nothing to do with the AppLoad command, the Startup Suite, acad*.lsp, the (autoload) function or anything else that existed in earlier releases. This is completely new, it has not replaced or broken any of the existing loading mechanisms, and is, in short, A Good Thing. Developers don’t have to use it, but those who do, and their customers, will have certain advantages. I have used it for the ClassicArray loading mechanism, and I expect to see it used by more and more plug-ins over time. It works fine with all of the usual AutoCAD add-on … Full post

AutoCAD 2012 – 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.

The most popular post on this blog, in terms of both hits and comments, is AutoCAD 2009 – Putting things back to “normal”. This is followed by AutoCAD 2010 – Putting things back to “normal”, with AutoCAD 2011 – Putting things back to “normal” not too far behind. As it seems many people find these posts useful, here’s an updated version for the latest release. Much of this post is based on older versions, but there are many additions and differences in this year’s “keep off my lawn” post.

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 … Full post

ClassicArray Release Candidate 2

I have now posted the second Release Candidate of ClassicArray™ (version number 0.7.0). The main changes from the first Release Candidate (0.6.0) are:

  • Help documentation, which you can also view here, now describes how to resolve an AutoCAD CUIx loading problem. (The problem is not specific to ClassicArray and can affect any CUIx file that is removed or relocated. More on that in a future blog post).
  • Timebomb mechanism now works 15 days after first use rather than a specific date. Also now allows the interface to still be used (but no arrays to be created) once the evaluation period has expired.
  • About dialog enhanced to show registration information and to provide access to a new registration dialog.

Barring disasters, I intend to release ClassicArray in this exact form (except for updating the version number to 1.0.0) in about a week.

Please see either www.classicarray.com or … Full post

ClassicArray Release Candidate – massive download bloat

I have just posted the Release Candidate of ClassicArray™ (version number 0.6.0). The main changes from Beta 2 (0.5.0) are:

  • Setup executables have been provided to provide easier installation and uninstallation.
  • Pretty comprehensive Help documentation is now in place, which you can also view here if you want to learn about the product without installing it.
  • Bug fixed with Path preview not displaying accurately when no path is selected.
  • Minor cosmetic dialog box fixes.
  • Timebomb has been moved on 7 days to 28 April.

Regrettably, the download file size has blown out to 787 KB because of the inclusion of the Help files and setup executables. There are two setup choices; one for all users (requires admin rights) and one for the current user only (admin rights not required). When installing the Release Candidate, it is not necessary to uninstall the Beta first. I would appreciate any … Full post

Why do you comment here?

One of the things that most pleases me about this blog is the amount of comments it gets. I’m sure there are several AutoCAD-related blogs that are much more frequently visited than this one, especially the Autodesk ones. However, I’m not aware of another AutoCAD blog with the volume of comments I see here. On average, each post here receives just under 5 comments, and the most popular subject for discusssion is now not far short of the 100 mark.

I recently went four complete calendar months without making a single post, but comments kept trickling in anyway. When I returned to normal posting, the commenters returned as if I had never been “away”. What’s up with that? I’m curious. Why do you comment here and not so much elsewhere? Or am I mistaken and there’s an AutoCAD blog I’ve forgotten that’s a hotbed of commentary?

AutoCAD 2012 – Massive download bloat

Note: this post is not an April fool’s joke. It may be ridiculous and hard to believe, but unfortunately it’s all true.

After I managed to overcome Autodesk’s obstructive download manger and download AutoCAD 2012, it became available on the Subscription site (when that site wasn’t running unusably slowly). Or it became kind-of available. Here’s what is actually available:

  • AutoCAD 2012 Multilingual 32 bit
    Download File Size: 2,080,558,319 bytes (1,984.2 MB)
  • AutoCAD 2012 English Korean Traditional-Chinese Simplified-Chinese Win 64bit
    Download File Size: 2,240,915,999 bytes (2,137.1 MB)

These file sizes are roughly double those of the AutoCAD 2012 English files I’ve already downloaded from the trial page and installed. The 32-bit English file is 1,144,011,680 bytes, or 55% of the size of what the Subscription site is trying to offer me.

Why? Because the Subscription downloads contain three bonus Asian language packs. It has … Full post

AutoCAD for Mac Update 2

As reported on Without a Net, there is a second update for AutoCAD 2011 for Mac. This will be welcome news to those of you who have discovered that AutoCAD crashes when using Copy/Paste after installing the 10.6.7 OS X update.

If you haven’t applied Update 1 yet, you will need to do that first. As always, read the readme before applying the update itself.

AutoCAD 2012 – Nudge encourages ‘bad’ drawings

If you preselect some objects in AutoCAD 2012 and hold down [Ctrl], then the objects will move a bit if you hit an arrow key. Great, cool!

Exactly how far do they move? Let’s try it, shall we. First time, the move was about 4.5565 units. Zoom around a bit and try again. This time, it’s about 11.6677 units. Zoom around a bit more and it’s different again. And again. What’s actually happening is that the Nudge feature is moving the objects by 3 pixels. What? Since when has AutoCAD dealt with object location in terms of pixels? Since 2012 came out. Does object snap help? No. So you can expect to see a bunch more drawings that have been eyed in. “Looks near enough to me!”

OK, so you can turn Snap on and have the objects nudged around in a more rational way, or just ignore the feature … Full post

ClassicArray pricing proposal

I am considering the following pricing model for ClassicArray™ when it’s released:

Individual licenses: $12
Up to 20-user license: $100
Up to 50-user license: $200
Up to 100-user license: $300
Unlimited site license: $500

Prices in US$, payment by PayPal, delivery by download only. Australian purchasers would have to pay 10% GST on top of that.

Comments? Suggestions?

ClassicArray Beta 2 (0.5.0)

I have just posted the second public Beta of ClassicArray™ (version number 0.5.0). There are some documentation updates (still no Help, though), and the main changes are:

  • Bugs fixed with rectangular arrays where single-row and/or column arrays confused AutoCAD.
  • The command now remembers its settings from one invocation to the next, within a single drawing session.
  • Timebomb has been moved on 7 days to 21 April.

The ReadMe.txt file in the zip explains how to uninstall the old version. Simply delete the old ClassicArray.bundle folder from the place you put it. Replace it with the new ClassicArray.bundle folder from the later zip file. Then try to break it!

Please see the main ClassicArray Beta post for the download, and add any comments there.

AutoCAD 2012 – How’s the Help now?

You may have noticed that the much-derided AutoCAD 2011 Help has had something of an update for AutoCAD 2012, integrating it with something called Autodesk Exchange. Rather than critique this myself, I’ll hand it over to you.

What do you think of AutoCAD 2012’s Help? Is it all better now? Is it fast, accurate and easy to use with a useful search facility? Or do you hate it and hope someone at Autodesk is scrambling to create a CHM version of it like last year? Please comment.

AutoCAD 2012 – ClassicArray Beta

People have already started to notice that AutoCAD 2012 has killed the dialog box interface for the Array command, and not everybody is happy about it. So I guess it’s time to launch ClassicArray™ Beta.

ClassicArray is an add-on for AutoCAD 2012 for Windows that allows the creation of arrays using a dialog box interface similar to that provided in AutoCAD from 2000 to 2011, but enhanced to include new AutoCAD 2012 functionality. I will create another post later have created a Help page that describes ClassicArray more fully, but for now here are the commands ClassicArray adds to AutoCAD:

ClassicArray (short form CA)
ClassicArrayRect (short form CAR)
ClassicArrayPolar (short form CAP)
ClassicArraypAth (short form CAA)

In addition, there are the same names with N appended, which default to creating non-associative arrays. For example, ClassicArraypAthN (short form CAAN) will create a non-associative path array. However, it is easy to create associative … Full post

AutoCAD 2012 – Missing a few things?

The Array dialog box isn’t the only thing you might notice by its absence in AutoCAD 2012. I’ll do a proper “Putting things back to normal” post later, but here’s a quick one for those of you wondering what happened to a few things that appear to be AWOL in 2012.

Are you missing your aerial viewer, blips and/or screen menu? They’re still there, but the commands are undefined. To get them back, just redefine the commands:

REDEFINE DSVIEWER
DSVIEWER

REDEFINE BLIPMODE
BLIPMODE 1

REDEFINE SCREENMENU
SCREENMENU 1

These features are deprecated. That means unless enough of you kick up a fuss about needing them, they are likely to vanish without trace in a release or two.

Edit: Jimmy Bergmark pointed out that the same applies to the TRACE command. If you need it, redefine it.

AutoCAD 2012 – Downloading the trial is a trial

Edit (October 2016): see this post to download Autodesk software easily.

Let’s say you’re trying to download some software and it insists on first installing some intermediary download manager. Do you think, “Great, this will make my life easier, things are bound to go quickly and smoothly now”? No, didn’t think so. How about when it’s by Akamai? Does that make you feel more confident? No, nor me.

If I download stuff without a manager, it just works. Sometimes it’s slow, but it works. If I use a general-purpose download manager that’s part of my browser, or one I chose to install and use (e.g. Free Download Manager), things generally go very well. If there’s a direct download link to use, success and a very quick download are almost guaranteed. But it seems that every time some company wants to force a download manager on me, something bad happens. Now … Full post
