The Dimensions dialog box can be opened by selecting View >> Dimensions or by clicking on the dimensions icon in the top toolbar. 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. You can also switch from displaying numeric values to displaying the name of the dimension. The appearance of the dimensions can be modified as well, including whether or not dots are shown on the ends of leader lines, whether the ends of dimensions have arrows or dots, and the size of those arrows and/or dots.

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.
