Dimensioning in AutoCAD
®
is a semi-automatic process; users contribute
part of the job and AutoCAD does the rest.
Users in linear dimensioning, for example, specify three points. The fi rst and
the second is the length to be dimensioned, and the third is the position of
the dimension line.
Accordingly, AutoCAD will generate the
Dimension block
automatically,
as shown in the following illustration:

consists of four parts. They are:

The Dimensioning process has two phases:
Creating dimension style(s)
Dimensioning your drawing
The dimension style will control the appearance of the
Dimension block
.
Each user will set up the style according to their needs.
