With this method, you always draw geometric objects at full scale (1:1) and
text, dimensions, and other annotation at a scale that will appear at the correct
size when you output the drawing.
For information about using annotative objects and scaling annotations
automatically, see
Scale Annotations (page 304).

Draw, Scale, and Annotate in Model Space
If you draw and plot from model space, you must determine and apply a scale
factor to annotate objects before you plot.
You can draw and plot entirely from model space. This method is useful
primarily for two-dimensional drawings that have a single view. With this
method, you use the following process:
■ Determine the unit of measurement (drawing units) for the drawing.
■ Specify the display style for the drawing unit.
■ Calculate and set the scale for dimensions, annotations, and blocks.
■ Draw at full scale (1:1) in model space.
■ Create the annotation and insert the blocks in model space.
■ Print the drawing at the predetermined scale.
You can also use objects if you want to scale annotations automatically. For
information about using annotative objects and scaling annotations
automatically, see
Scale Annotations (page 304).
Determine the Unit of Measurement
Before you begin drawing in model space, you determine the unit of
measurement (drawing units) that you plan to use. You decide what each unit
on the screen represents, such as an inch, a millimeter, a kilometer, or some
other unit of measurement. For example, if you are drawing a motor part, you
might decide that one drawing unit equals a millimeter. If you are drawing a
map, you might decide that one unit equals a kilometer.
