Sets up units of measure and precision readout for the length, area, or angle values in a drawing.

The precision readout sets the number of significant figures to display. It sets the accuracy of the unit readout value. The precision setting does not alter the numbers that you type into the fields, only the display of the numbers in the field. Values ending in 5 are rounded up. For example, if the precision readout is .123 and you draw a line that is 2.1056 inches long, then the line value length is rounded. The length value appears as 2.106 inches long. If you are using mm as your drawing sheet units, you can have the values display in the fields as 3.5 mm or 3.50 mm.

When you set options on this tab for the units in a document, the settings do not affect the dimensional values for the document. You can set options for the dimensional value by selecting a dimension and clicking Properties on the Edit menu. You can also set the units by modifying a dimension style with Style on the Format menu.
