Add Bearing Load Example (VB.NET)

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.
