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 on page 656.
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.
Specify the Display Style of Drawing Units
Once you have determined a drawing unit for the drawing, you need to specify
the style for displaying the drawing unit, which includes the unit type and
precision. For example, a value of 14.5 can be displayed as 14.500, 14-1/2, or
1'2-1/2".
Specify the display style of drawing units with the UNITS command. The
default drawing unit type is decimal.
