AEC Dimensions

AutoCAD Architecture offers different ways of dimensioning objects and points in a drawing. AEC dimensions can be
associative to objects or be used to dimension user-specified points in the drawing. If you create an associative dimension,
the dimension value changes when the object changes its measurements.

Using Grips to Modify AEC Dimensions
When you select an AEC dimension, various grips are displayed. You can use the grips to add and remove dimension
points, move dimension chains, change the offset of extension lines, and override wall component dimensions.

Dimensioning Wall Components
When dimensioning wall components, you have the option of using the center of the component or either side as the
dimension point. For example, you can dimension a wall component from its center or from one of its edges. You can
also dimension wall components according to their structural function.
Grips for the individual component dimension points allow you to override style-defined dimension points on walls
to accommodate special cases.

Overriding Dimension Values
The dimension values in an AEC dimension are calculated from the actual current dimensions of associated objects.
You can override a value with a manually inserted value. For detailed information, see Overriding Dimension Values
and Hiding Dimension Segments" on page 1874.
