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.
