Access Load Case Manager Example (C#)
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.
