Get Spot Weld Connector Example (C#)

This example shows how to get the properties of a spot weld connector.

// Preconditions:
// 1. Add the SOLIDWORKS Simulation as an add-in (in SOLIDWORKS, click 
//    Tools > Add-ins > SOLIDWORKS Simulation > OK).

// 2. Add the SOLIDWORKS Simulation primary interop assembly as a reference
//    (in the IDE, click Project > Add Reference > .NET > 
//    SolidWorks.Interop.cosworks > OK).

// 3. Ensure the specified part exists.
// 4. Open the Immediate window.
// Postconditions:
// 1. Opens the specified part.
// 2. Activates the Ready study.
// 3. Prints properties of Spot Weld Connector-1 to the Immediate window.
// 4. Meshes the model.
// 5. Analyzes Ready.
// 6. Inspect the Immediate window, the Simulation study tree, and the
//    graphics area.
// NOTE: Because this part is used elsewhere, do not save any changes.
