Create Route Through Sketch Entities Example (C#)

This example shows how to create a route by specifying sketch entity types and their IDs.

//--------------------------------------------
// Preconditions:
// 1. Add SolidWorks Routing as an add-in 
//    (in SolidWorks, click Tools > Add-Ins > SolidWorks Routing).
// 2. Add the SolidWorks Routing interop assembly as a reference 
//    (right-click the project in Project Explorer, click Add Reference, 
//    browse install_dir\api\redist\CLR2, and select 
//    SolidWorks.Interop.SWRoutingLib.dll).
// 3. Open:
//    install_dir\samples\tutorial\api\AutoRouteThroughSketchEntities.sldasm
// 4. Open the Immediate window.
// 5. Run the macro.
//
// Postconditions:
// 1. Creates a route using the sketch
//    points whose entity types and IDs were passed
//    to IAutoRoute::CreateRouteThroughSketchEntities.
// 2. Examine the the assembly document to verify.
// 3. Examine the Immediate window.
//
// NOTE: Because the assembly is used elsewhere,
// do not save any changes when closing it.
