### Conventions

The Dimension tab on the Setup Options dialog box (Edit | Preferences | Setup) allows you to define parameters for the displayed dimensions.

- All angles can be represented 1-5 places to the right of the decimal. The actual number displayed is determined by the parameters set in the Dimension tab.

- All lengths, distances (x_cord, y_cord, z_cord, diam, height, length, etc.), and vectors (i_vec, j_vec, k_vec) in the dimensions are represented 1-5 places to the right of the decimal. The actual nominal that will be displayed is determined by the parameters set in the Dimension tab.

For information on this Dimension tab, see the "Setup Options: Dimension tab" topic in the "Setting your Preferences" chapter.
