Create Structural Costing Analysis Example (C#)

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

//------------------------------------------------
// Preconditions:
// 1. Specified part template exists.
// 2. Add a reference to SolidWorks.Interop.sldcostingapi.dll.
// 3. Open the Immediate window.
// 4. Run the macro.
//
// Postconditions:
// 1. Creates a weldment part.
// 2. Gets the CostingManager.
// 3. Gets the Costing part.
// 4. Sets the Costing manufacturing method
//    to structural and gets the Costing body.
// 5. Gets the common Costing analysis and the
//    structural 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 structural Costing analysis
//    parameters.
// 9. Gets the total manufacturing cost.
//10. Examine the Immediate window to see the
//    results of steps 6 through 9.
