When you drag a routing component with multiple CPoints to create a route, you can select CPoints to include in the route from the Multiple CPoints dialog box, provided the component is set up for multiple CPoint selection.
You can also right-click a CPoint in the graphics area to add or remove it from a route.
From the Save Components to Library page of the Routing Component Wizard, you can control the treatment of multiple CPoints when creating or editing routing components. In the wizard, select Select CPoints to select which CPoints to route.
