Access Load Case Manager Example (VB.NET)

This example shows how to access the Load Case Manager to define load cases and load case combinations.

' 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 that the specified model exists.
' Postconditions:
' 1. Gets the Ready study.
' 2. Opens the Load Case Manager.
' 3. Adds primary load cases and load case combinations.
' 4. Analyzes Ready using all primary load cases and load case combinations.
' 5. Creates a results displacement plot.

' 6. Click each primary load case and load case combination in the
'    Results View tab of the Load Case Manager. Inspect the result data
'    in the graphics area after each click.
' NOTE: Because the model is used elsewhere, do not save changes.
