Modeling systems > Associating system model blocks with other objects using trace links
Create a trace link from a system model block
You can create a trace link when you want to define a directional defining-complying relationship between objects. For example, you can create a trace link between a requirement and a system model block.
Procedure
Select the Table view.
Select one or more object revisions to which you want to create a trace link and set as the defining object. Press Ctrl or Shift to select multiple objects. These objects represent your Start (defining) objects in the trace link relationship.
Click New > Trace Link.
Note: You can use the keyboard shortcut Alt + L to create a trace link.
The Trace Link panel opens, and the selected defining objects appear in the Start section.
Choose the object you want to link to as the End (complying) objects by doing one of the following:
Note: You can create trace links while working among multiple browser windows. You can use the clipboard to add either multiple Start objects or End objects — but not multiple Start objects and multiple End objects at once.
- To add all clipboard objects to Start or End (in the New tab), click Paste to the right of Start or End.
- To select an object from multiple objects on the clipboard, click Add, then in the Palette tab, select an object from the Clipboard section.
- To select a favorite or recently viewed object, click Add, then click the Palette tab and select the object from the Favorites or Recent section.
- To search for an existing object, click Add, then click the Search tab, type search terms, and click Search. Select the object from the search results.
- Click Add. The selected objects are added to the End section.
If the Type list is available, choose the trace link type you are creating. If the type has required properties, they appear directly after the Type list — you must enter them to create a trace link.
Click Create. The trace link is created.
To view the trace link, open the defining object, and click the Trace Links tab. The complying object appears in the Complying Objects list or table.
