Autocad: Creating a Drawing from Scratch

When creating a new drawing, you have the option to create a new drawing from
scratch rather than basing it on a drawing template. The only options you have to
choose from are the Imperial (inches, feet, and so on) and Metric (millimeter, meter,
and so on) measurement options, which affect the linetypes and hatch patterns used
for the drawing; otherwise, the drawing file is created with all the default drawing settings,
and no named objects, such as layers or text styles, are created in the drawing.

Practice creating a new drawing from scratch with the Imperial measurement setting.
1. Choose File➪New.
2. In the Select Template dialog box, click the drop-down arrow next to the Open
button and click Open with No Template - Imperial.
A new drawing is created with only the measurement setting set to Imperial and
all other settings set to their default values.
3. Close the drawing without saving it.
