   • Click File and open an industry model drawing or template.
2. Expand the industry model node.
3. On the right pane, under Industry Model Settings, on the navigation pane, click the Extensions link.
4. Select Dimension Extension.
5. Click Save to add the topic Dimension.

   This topic groups dimensioning feature classes for aligned dimensioning and orthogonal dimensioning, and the label definitions.

   The label definitions are used to inscribe the dimension values. The values are stored in the dimension line feature class (CALCULATED_x and MEASURED_x). The label definitions use the LINE_TYPE attribute , and the POINT_TYPE attribute to distinguish between the dimensioning types.

6. Make sure that the Dimensioning feature classes are added to the industry model explorer.
7. Define the stylization of the dimensioning layers in the Display Model.
