AutoCAD Training - 2007 - 8115-Dimensioning Smarter with Associative Dimensions.html

In this project you learn how to dimension objects with associative dimensions. Unlike standard dimensions, which must be recreated, edited along with objects in order to accurately reflect geometric values, associative dimensions automatically update when the geometry they measure changes. This insures that dimensions are always accurate.

Not all drawing offices use associative dimensions because they are incompatible with AutoCAD versions before AutoCAD 2002. Nevertheless, your office may wish to consider updating its drawing standards include the use of associative dimensions because they really can save you a great deal of time and effort. You will find they practically eliminate the use of the dimension scale factor (DIMSCALE) and dimension factors (DIMLFAC) which are a constant source of hassle for many offices.
In this tutorial you learn how to:

* Make AutoCAD create associative dimensions.
* Create a scaled viewport in a layout.
* Dimension objects displayed in a layout.
* Change dimensioned objects.

By the time you complete this project you should feel comfortable working with associative dimensions.
