Process Overview: Creating AEC Dimensions
An AEC dimension consists of a number of components and settings to make
it the optimal tool for dimensioning objects.
TIP AutoCAD Architecture ships with predefined dimension tools for many uses.
Before you create a new tool or AEC or AutoCAD dimension style, look through
the templates to find an existing tool or style that contains most or all of your
desired settings. You can then modify it for your purposes, if necessary.
The general process for creating AEC dimensions involves the following steps:
1 Specify the drawing options for the AEC dimension, as described in
Specifying AEC Dimension Preferences on page 3365.
Important settings include the dimension unit, superscripting preferences,
and the automatic scaling of AutoCAD dimension styles.
2 Verify that there is an AutoCAD dimension style that has the settings
you need. If necessary, create a new AutoCAD dimension style that defines
the color of the dimension lines, size and font of the dimension text,
arrows, unit format, and unit precision.
For more information, see “Use Dimension Styles” in the AutoCAD help.
3 If you are dimensioning walls, create or modify a wall style with
dimension settings for wall components.
For more information, see Defining the Dimension Settings for Wall
Components on page 1295.
4 Create an AEC dimension style that specifies the desired values for the
following settings:
■ number of dimension chains
■ object types to be dimensioned (for example, walls or mass elements)
■ object points to be dimensioned (for example, wall components and
wall intersections)
■ underlying AutoCAD dimension style
For more information, see AEC Dimension Styles on page 3415.
5 Use a dimension tool and dimension objects and points in the drawing.
For more information, see Creating an AEC Dimension with User-Specified
Settings on page 3370.
