For consistency, instead of simply picking a location for a dimension, you can specify its distance from the object. At the Specify dimension line location prompt, you can enter one of the following to place the dimension .5 units above the object (for example):
@0,.5 @.5<90

The Mtext Editor has three options that many people miss. In the Mtext window, select the text you’ve entered and right- click inside the text area. Choose one of the options:
Change Case to change the text to all uppercase or all lowercase. Choose Remove Formatting to return all text to Txt font and remove […]
There are several ways you can let AutoCAD do some quick arithmetic for you when you need a distance. Let’s say you’re drawing a line and you want to use direct distance entry to specify the length. What you know is that that line should be 4.372 plus 3.925. Of course, you could use a […]
Some people (mostly architectural types) like their fractions like this:
Others (mostly mechanical types) like their fractions like this:
These are called stacked fractions. And some people like their fractions unstacked. Of course, unstacked fractions are easy; it’s the stacked ones that require a bit of knowledge.
Ted Harris e-mailed me an AutoLISP routine that he uses to follow a linear dimension with a continued dimension. He notes, “one rarely enters one Dim, at least in a production environment.” I’ve updated his solution for recent versions of AutoCAD.
Normally, dimensions are associative, meaning that they change when you edit objects to which they’re attached.
Drawings created in releases 2000 and earlier are not associative. Sometimes, you’ll get a drawing that was created a long time ago and realize that the dimensions aren’t associative.
To make them associative, type dimassoc (a system variable) on […]
AutoCAD 2005 and earlier doesn’t have a way to dimension arc length, but Leonid Nemirovsky has come up with an AutoLISP routine that dimensions arc lengths very nicely. You can download it here.
Here’s the result:
Leonid has many, many more AutoLISP routines on his site, Better Than Nothing AutoLISP.
The new fields in AutoCAD 2005 make it easy to add text that updates automatically. For example, you can put today’s date, the sheet number, and Drawn By initials in your title block. However, if you don’t have 2005 but have Express Tools (they come with 2004 and you can purchase them for $149 if […]
Do you keep supporting notes for your AutoCAD drawings on a notepad next to your computer? Do you sometimes need to jot down tasks to complete, explanations of objects, or locations of supporting data?
Instead of using pen and paper, you can insert this information into your drawing and have easy access to it whenever […]
Dimension styles are a great way to organize and manage your dimensions. Usually, you use the DIMSTYLE command (Dimension>Dimension Style or Annotate tab> Dimensions> Dimension Style).
But you can quickly create a new dimension style from an existing dimension with the Properties palette. Select a dimension and display the Properties palette.
