Create Auto Route Example (C#)

//---------------------------------------------------------------------------
// Preconditions:
//
// 1. Add SolidWorks Routing as an add-in

//   (in SolidWorks select Tools > Add-Ins > SolidWorks Routing).
// 2. Add SolidWorks.Interop.SWRoutingLib.dll as a reference

//   (in the IDE right-click the project, select Add Reference,

//    and browse <SolidWorks_install_dir>\api\redist).
// 3. Open:

// <SolidWorks_install_dir>\samples\tutorial\api\top_assy_connectors.sldasm
// 4. In Tools > Options > System Options > Routing > Routing File Locations,

//    add locations of your SolidWorks Routing files.
// 5. Modify the namespace to match the name of your C# project.
// 6. Select the assembly that contains Route1 in the FeatureManager design tree.
//    7. Open an Immediate Window.

// Postconditions: Auto Route connects the pins in orthogonal fashion

// in the electronic housing.
//
// NOTE: Because the assembly is used in a SolidWorks demo,

// do not save any changes to it.
