Draw linear dimensions.
The most common dimension you'll use is the linear dimension.
Knowing how to place a linear dimension is a big first step in learning how to dimension in
AutoCAD.
Master It
Name the three locations you're asked for when placing a linear dimension.
Edit dimensions.
Dimensions often change in the course of a project, so you should know
how to make changes to dimension text or other parts of a dimension.
Master It
How do you start the command to edit dimension text?
Dimension non-orthogonal objects.
Not everything you dimension will use linear dimen-
sions. AutoCAD offers a set of dimension tools for dimensioning objects that aren't made up
of straight lines.
Master It
Name some of the types of objects for which a linear dimension isn't
appropriate.
Add a note with a leader arrow.
In addition to dimensions, you'll probably add lots of
notes with arrows pointing to features in a design. AutoCAD offers the multileader for this
purpose.
Master It
What two types of objects does the multileader combine?
Apply ordinate dimensions.
When accuracy counts, ordinate dimensions are often used
because they measure distances that are similar to coordinates from a single feature.
Master It
What AutoCAD feature that isn't strictly associated with dimensions do you
use for ordinate dimensions?
Add tolerance notation.
Mechanical drafting often requires the use of special notation
to describe tolerances. AutoCAD offers some predefined symbols that address the need to
include tolerance notation in a drawing.

How do you open the Geometric Tolerance dialog box?
