You can start a new drawing several ways, including starting from scratch or using a template file. In each case, you can choose the units of measurement and other unit format conventions.
You can use several methods to find and open drawings, even damaged drawings. You can save and backup drawings automatically.
If a drawing file is damaged or if your program terminates unexpectedly, you can recover some or all of the data by using commands to find and correct errors, or by reverting to a backup file.
Drawings are easier to interpret if you set standards to enforce consistency. You can set standards for layer names, dimension styles, and other elements; check drawings against these standards; and then change any properties that do not conform.
