Use this procedure to create a display representation for a selected object. You create a display representation by duplicating an existing one for the object.
Each object has one or more display representations, depending on whether the object needs to change in different views. Select an existing representation that is similar to the one you want to create. That way, the display properties are available for you to customize in the new representation.
For example, to create a display representation for stairs and use a custom break mark, duplicate a plan display representation for stairs that contains settings for the break mark.
- Click
. 
- Expand Representations by Object.
- In the left pane of the Display Manager, select the object for which to create the new display representation.
- In the right pane, right-click the display representation to duplicate, and click Duplicate.
- Enter a name for the new display representation, and press Enter.
The new display representation has the display properties of the representation you duplicated.
The display representation created in the right pane is not listed in the Representations by Object directory in the left pane until you close and reopen the Display Manager.
- Double-click the new display representation to edit its properties.
- Assign the display representation to the display sets in which they will be used.
- Click OK.
You can click Apply instead of OK to save the changes and continue working in the Display Manager.
