This illustration shows the Dimension dialog box.

At the top of the dialog box is the title bar. In the top left is the Dimension title, and in the top right is the Help and Close icons.

Below the title bar the following fields are listed top to bottom: Name (free-form text field), Type (populates when a data object is selected), Process (drop-down list), and Data Object (free-form text field with Search button to the right of the text field).

Below those, there is a table that displays the ranges. The table has three columns, listed left to right: Name, StartPoint, and Range. There is one row in the table with a name and range of "otherwise."
