Wiki for AutoLISP

Greg Robinson, who I had the pleasure of meeting at Autodesk some 11 years ago in the run-up to Release 14, has started a Wiki for AutoLISP and other AutoCAD-based source code. I’m a big fan of LISP in AutoCAD, so I’m happy to see this resource available for users. It’s in its infancy right now, but if you pick the All Pages link you’ll see that there already dozens of routines available, one of which may help you with something you need to do. Here’s the link to the main page: http://lispwiki.com/

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 …

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 …

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 …

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: 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 …

AutoCAD tip – more on the Oops command

In a comment on my Five More Simple Tips for AutoCAD post, Jeremy had some questions about the Oops command. I thought I would explain the command in more detail in another post so more people will see it. The first thing to understand is that Oops varies from Undo/U in that it only reverses those commands that erase objects. The Erase command is obvious, and the same applies to pre-selecting objects and hitting the Delete key, but the Block and Wblock commands can also erase the objects that go to make up the block. In such cases Oops can …

Five More Simple Tips for AutoCAD

More simple AutoCAD tips, as promised: If you erase some objects, draw a few things and then want your erased objects back without losing the things you drew in the meantime, enter OOPS rather than undoing the commands. At any Select objects: prompt, you can select using a triangle, non-orthogonal rectangle or other odd shapes, by entering the WPolygon (WP) or CPolygon (CP) options. If you have a paper space viewport entirely inside another one, it can be hard to make that viewport current just by picking in it. Try Ctrl+R to cycle through viewports instead. Move some objects, rotate …

Five Simple Tips for AutoCAD

As my forced change to a different blog theme (thanks IE7) has meant the demise of my random AutoCAD tip feature, you may as well have the tips in a blog post instead. Here are the first five. These are fairly simple tips that apply to all recent releases. You probably know most of them, but just in case… If you need to draw circles, slots or rectangles around multiple text objects, use the Express Tools command TCIRCLE (Express > Text > Enclose Text with Object). When using the TRIM or EXTEND command, you don’t have to select any edges. …

Thinking of registering a domain name? Just do it!

If you are thinking of putting yourself or your company out there with your own domain name (e.g. cadnauseam.com), there are many, many sites out there that allow you to enter a domain name and see if it’s available. Don’t use them. Why not? Because some of those sites will then immediately register that domain. You won’t be able to register it until that company decides to release it, which of course it will do if you choose to use that company’s overpriced domain registration services. This particularly unethical practice is known as domain tasting and is now the subject …

AutoCAD tip – persuade Open to highlight your drawing

In AutoCAD, when you have a drawing open and you go to open another, does Open automatically scroll down and highlight your current drawing? This can be very handy when you’re working your way though a set of drawings. If this isn’t happening for you, here’s how to make it do so. In Explorer, go to Tools > Folder Options > View tab and turn off the toggle for Hide extensions for known file types. (Windows XP shown). This is the first thing many people do when setting up a new Windows system. If you fit into this category, you …

blognauseam.com lives! Plus a web browser tip

I have registered the domain name blognauseam.com because: a) it will stop anybody else grabbing it; and b) it will make it easier for people to remember the URL if they don’t have me bookmarked. No changes are required to your bookmarks or links, I just redirected blognauseam.com to blog.cadnauseam.com and will continue to use blog.cadnauseam.com. That leads me to a web browser tip. I’m sure most of you already know this, but if one or two of you go “Ah! Cool…” then it was worth typing it up. When entering a .com URL, you can save time by just …
