Create Auto Route Example (C#)

//----------------------------------------------------------------------------
// Preconditions:
// 1. In SOLIDWORKS, click Tools > Add-Ins > SOLIDWORKS Routing.
// 2. In the IDE, right-click the project, select Add Reference,
//    browse install_dir\api\redist\CLR2, and click
//    SolidWorks.Interop.SWRoutingLib.dll).
// 3. In Tools > Options > System Options > Routing > Routing File Locations,
//    add the locations of your SOLIDWORKS routing files.
// 4. Open a routing assembly that contains Route1 and two sketch points.
// 5. Modify the swModel.Extension.SelectByID2 parameters to select two sketch
//    points through which to auto route.
// 6. Select the assembly that contains Route1 in the FeatureManager design tree.
// 7. Open an Immediate Window.
//
// Postconditions: Auto Route connects the selected sketch points.
//
// NOTE: Because the assembly is used elsewhere, do not save changes.
