Create a Drawing for a Pipe 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 install_dir\api\redist).
// 3. Create a piping BOM template named piping_template.sldbomtbt.
// 4. Add a column with header "Length" to the piping BOM template.
// 5. Ensure that the specified piping BOM and sheet format
//    template paths exist.
// 6. In Tools > Options > Routing > Routing File Locations,
//    add the locations of your SOLIDWORKS Routing files.
// 7. In Tools > Options > File Locations, add the location of
//    your sheet format templates.
// 8. Open:
//    public_documents\samples\tutorial\routing-pipes\fittings\reducerroute.sldasm
// 9. Rename the namespace to match the name of your C# project.
//
// Postconditions: A drawing of the pipe assembly is created
// in a standard format and includes auto balloons, a bill of
// materials, and a route sketch.
//
// NOTE: Because this assembly is used elsewhere,
// do not save any changes to it.
