Create Plastic Costing Analysis Example (C#)

This example shows how to create a plastic Costing analysis of a part.

// Preconditions:
// 1. Specified part to open exists.
// 2. Add a reference to SolidWorks.Interop.sldcostingapi.dll.
// 3. Open the Immediate window.
// 4. Run the macro.
// Postconditions:
// 1. Opens the specified part.
// 2. Gets the CostingManager.
// 3. Gets the Costing part.
// 4. Sets the Costing manufacturing method
//    to plastic and gets the Costing body.
// 5. Gets the common Costing analysis and 
//    the plastic Costing analysis.
// 6. Gets the material classes from the Costing template
//    and sets the material class.
// 7. Gets the material names from the Costing template
//    and sets the material for the material class.
// 8. Sets and gets plastic Costing analysis
//    parameters.
// 9. Gets the total manufacturing cost.
//10. Examine the Immediate window to see the
//    results of steps 6 through 9.
// NOTE: Because the part is used elsewhere, do
// not save changes when closing it.
