Use Clash Check to detect component interferences.
- On the main toolbar, click Clash Check.
A list of clashes is created in the Clashes folder in the browser.
- To display a detail view of a component clash, expand the Clashes folder in the browser, and click a clash result.
- To dismiss the clash detail view, click another clash result, or press ESC to exit the Clash Check command.
Tip: 
When you or your collaborators change the mockup model, the Clashes folder in the browser is marked, and clash results are shaded. To recalculate clashes, right-click the Clashes folder, and click Update.
