The Dimensions dialog box can be opened by selecting View >> Dimensions or by right clicking and selecting Dimensions from the popup menu. The Dimensions dialog box controls the display of dimensions on the screen.

There are controls in the top of the dialog box to change the dimension units from inches to millimeters, to set the number of decimal places, and to change the dimension text size.

The sliders next to the dimension check boxes control how far offset the dimensions will be displayed from the reference. With angular dimensions, dragging the slider far to the right will increase the diameter of the dimension arc. Dragging the slider to the left will switch to display the supplement of the original angle (180° - original angle).

Dimensions are divided into categories. You can display all the dimensions in a category by clicking the Select all button. You can clear all the dimensions in a category by clicking the Unselect all button.
