Primary units

Dimensions are used to measure distance or size and, therefore, must be measured with units. This pane allows you to control units for the primary dimension value.

Note that some of the fields on the Primary units pane have a Value button. This is a two-state button. When it is not pressed, the field beside it is used to specify a percentage of text height. For example, 0.75 means 75% of the text height. When pressed, the field beside it is used to specify an absolute value in terms of the part units. For example, when inches are the part units, 0.75 means ¾ of an inch.

- - Units

The units in which the dimension is calculated. Available units are Inches, Millimeters, Feet, Centimeters, Yards, Meters and User. If you select User, then the Conversion factor field becomes available so you can define the User units.

- - Conversion factor

Conversion from part units to the dimension units. For example, if the part is created in Inches and the dimensions are set to millimeters, the conversion factor is 25.4. The number of inches times 25.4 equals the number of millimeters.

- - Display unit label
