Drawing Units
Drawing units defi the linear and angular units of measurement used while fine
drawing and the precision to which these measurements display. You determine what
“1 unit” means in AutoCAD. For example, 1 unit can mean 1 inch, 1 millimeter, 1 meter,
or 1 mile. Most AutoCAD users generally think of 1 unit to be 1 inch or 1 millimeter.
Access the
Drawing Units
dialog box to set linear and angular units. See Figure 2-18.
Specify linear unit characteristics in the
Length
area. Use the
Type:
drop-down list to
set the linear units format, and use the
Precision:
drop-down list to specify the preci-
sion of linear units. Figure 2-19 describes linear unit formats.
Set the angular unit format and precision in the
Type:
and
Precision:
drop-down
lists in the
Angle
area of the
Drawing Units
dialog box. To change the direction for
angular measurements to clockwise from the default setting of counterclockwise,
select the
Clockwise
check box.

This textbook explains paper space when appropriate. Until you are ready
to lay out a drawing, all of your drawing and drawing setup should occur in
model space. Model space is active bydefault when you start a drawingfrom
scratch and when you begin a file using one of several available templates. fi
Activate model space in all current drawings and custom templates.

Paper space is the environment in which you lay out model space geometry to complete the drawing
and prepare for plotting or export. This example shows common items added to a layout sheet,
including an ASME border, title block, revision block, angle of projection block, and general notes.
