In SolidWorks 2013, The Auto Route tool includes an option to create a route based on existing geometry. To route along geometry, specify a start point, one or more planar faces, and an endpoint in the Auto Route PropertyManager. Routing automatically creates a route from the start point to the end point that runs parallel to the faces. You can specify the distance between the route and each planar face. This makes it easy to create a route that maintains a specific distance from walls and other planar surfaces. You can also specify if the route should include a covering for dimensions, and if it should use a centerline dimension.
