Tool palettes will rank as "Best New Feature" for years to come, but I think Fields easily take second place. I'm learning more about them myself and I'll contribute insights to this column as time and space permits. On the design side of things, I'm finding more drawings with curved walls so the new A2006 dimensioning features relating to arcs come in very handy.
The ability to add a background mask to Mtext objects showed up in A2005, but the Text Mask Express tool has been out there since dirt so I thought I'd run down some comparisons for you so you can make your choice. If you have AutoCAD 2004 or Express Tools with A2002 or previous, you only have Text Mask at your disposal. DesignCenter Part II covers that feature as it relates to blocks and specifically tool palettes.
In mid-June I received a notice from Autodesk that my AutoCAD Toolbelt seminar proposal was accepted for presentation at Autodesk University this year. There were over 1000 submissions from more than 400 individual presenters, so I am quite honored to have been selected. This year it will be held at a Walt Disney World Swan and Dolphin resort, Orlando, Florida: November 28 - December 1, 2005. For more information, go to http://www.autodeskevents.com/au2005/. My seminar (presently) is scheduled for Monday, November 28 from 1:00 - 2:30. If you are able to make it down there, please come by and say hello; I love to meet my readers!

Blessings to one and all,
Wonderful feature and very easy to implement. I could teach on fields for a couple hours but, alas, I only have this non-verbal venue so let me show you a cool application for a Field in AutoCAD 2005 and 2006.
Using the Field feature, you can now take some of the raw data laying around in AutoCAD, as well as your computer, and add it to the drawing as Mtext, an attribute, or as a simple field.
One application for a field is to access the stored file information and time/date information from your computer and create a plot stamp with the desired configuration. This is optimally done using Mtext.
Note: You can change the Height or Justification at this point or after you have placed the text.
Tip: Turn off the gray background mask color for the data field on the User Preferences tab of Options. The gray background will not print, it just let's you know it's a field.
Tip: Since the Field value appears in the Mtext editor, you can add text as necessary. In the example, I added the "Drawing" and "Date" text in bold, then underlined the field values.
If you're doing bids on materials and you have an arc you need to dimension for the finish material/paint/plaster, etc., you need a more accurate accounting of the length of an arc than a linear dimension. AutoCAD 2006 brings two new arc-related features to the table: Arc Length and Jogged Dimension (for a long radius).
The Symbols and Arrows tab of the A2006 Dimension Style dialog includes areas for Arc Length Symbol as well as Radius Dimension Jog. The following exercises are based upon the setting shown in the figure. If you don't have a drawing with an arc in it, just draw one and to see how it works. I'm using a drawing with Architectural units for the drawing units as well as the dimensioning units.
Specify center location override: [Blue dot]
Dimension text = 62'-10 9/16"
Specify dimension line location: [Black dot]
Specify jog location: [Red dot]
Beginning in AutoCAD 2005, the Mtext shortcut menu has an item for Background Mask. Those of you who remember the Bonus Tools in R14 will also remember a Text Mask routine which is still around in the Express Tools of A2004 - A2006. Which is best?
First, they all do the same thing: create an opaque background for the selected Text (Express Tool only) or Mtext (Express or Mtext shortcut feature). With that understanding, let me review the simple differences between the Mtext feature of Background Mask and the Express Tool of Text Mask.
Dtext: The Background Mask routine in A2005/A2006 can only be invoked from the Mtext shortcut menu.
Separate words in Mtext: The background mask applies to the entire Mtext object. You cannot specify a word or phrase or paragraph to mask.
Note: If you check the box for Use Drawing Background Color, the opaque rectangle behind the text will be the same color as your drawing screen, typically White or Black, depending on if you're in Model or Paper space.
Tip: To adjust the display of the fill color, you may want to change the justification of the text.
Dtext as well as Mtext: You can select both Mtext or Dtext objects to mask.
Multiple Mask types: The mask object is grouped with the selected text. Specify a Wipeout, Solid, or 3D Face as the masking object.
Current settings: Offset factor = 0.3500, Mask type = Wipeout
Select text objects to mask or [Masktype/Offset]:
Major Tip: Since the text mask object is grouped with the selected text, it is important that you make sure the Pickstyle variable is set to 3. This enables the mask object to be moved or copied with the text.
Now that you're acquainted with what the DesignCenter is capable of, let's look at some more ways in which it can be used.
Although the tool palette feature was first introduced in AutoCAD 2004, the ability to drag objects (blocks, dimensions, etc.) directly onto a tool palette was not implemented until AutoCAD 2005. Therefore, in A2004 you use DesignCenter to populate an existing tool palette or create an entirely new tool palette from existing blocks or drawings.
Note: For more on Tool Palettes in A2004, take a look at my March 2004 column. For additional palette features that were added to AutoCAD 2005, take a look at the November 2004 article.
Regardless of your version - A2004 / A2005 / A2006 - if you have a drawing containing blocks, you can make a tool palette containing all the blocks from the drawing with a single click. Seriously. And what if you have a folder containing .DWG files you "Wblocked out" in an effort to make blocks you could insert into other drawings? Make a palette!
Next issue we'll look at even more applications for DesignCenter!
