Add Bearing Load Example (C#)

This example shows how to add a bearing load and get its properties.

NOTE: To get persistent reference identifiers (PIDs) for model selections, you can use pidcollector.exe or IModelDocExtension::GetPersistReference3.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Add the SOLIDWORKS Simulation as an add-in
//    (in SOLIDWORKS, click Tools > Add-ins > SOLIDWORKS Simulation).
// 2. Add the SOLIDWORKS Simulation primary interop assembly as 
//    a reference (in the IDE's Project Explorer, right-click
//    the project name, click Add Reference, click the Browse tab,
//    navigate to install_dir\api\redist\CLR2
//    click SolidWorks.Interop.cosworks.dll, and click OK).
// 3. Ensure that the specified model document exists.
// 4. Ensure that the specified material library exists.
// 5. Open an Immediate window.
//
// Postconditions:
//  1. Opens the specified model document.
//  2. Inserts Coordinate System1 in the FeatureManager design tree.
//  3. Creates new study, Static1.
//  4. Applies AISI 1020 steel to the solid bodies in the model.
//  5. Adds BearingLoads-1 to the Simulation study tree of Static1.
//  6. Prints the properties of BearingLoads-1 to the Immediate window.
//  7. Meshes the bodies in the model.
//  8. Sets the study options for Static1.
//  9. Analyzes Static1.
// 10. Inspect the Immediate window, FeatureManager design tree, and
//     Simulation study tree.
//
// NOTE: Because the model is used elsewhere, do not save changes.
