The dimension measurements in your drawing use a specific unit, whether millimeters, inches, or something else. But it’s common to need to show a second unit — perhaps a metric measurement if you’re using inches, or vice versa.
You define an alternate measurement on the Alternate Units tab of the Dimension Style dialog box. For more [...]
This is a guest post by Sanjay Kulkarni, an AutoCAD programmer.
Learning AutoLISP (or any other programming language) doesn’t compel you to become a programmer. You can still use it to better understand the internal working of AutoCAD and enhance your interactive working skill. This can also give you an edge over others.

It’s always good to keep to your dimension styles as much as possible, but sometimes a situation requires an exception. You can create an override, which is a sub-dimension style that varies from its parent style.
Follow these steps:
Choose Dimension> Style (in 2009, choose Annotate tab> Dimensions panel> Dimension Style).

Usually, it’s best to format your dimensions using a dimension style. If you want an exception to the style, create an override. To create an override, choose Dimension > Dimension Style and click the Override button in the Dimension Style Manager. This method is the best way to maintain your CAD standards.

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 [...]
