Create Amplitude Plot and Set Mode Shape Example (C#)

This example shows how to create an amplitude plot and set its mode shape number.

//---------------------------------------------------------------------------
// 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. Open public_documents\samples\Simulation Examples\tutor1.sldprt.
// 4. Create a frequency study and apply material to the model.
//
// Postconditions: 
// 1. Activates the Frequency1 study.
// 2. Meshes and analyzes the study.
// 3. Creates one or more default resultant amplitude plots, depending on your
//    Tools > Simulation > Options > Default Options > Frequency/Buckling Study
//    Results settings.
// 4. Creates another resultant amplitude plot and sets its mode shape number
//    to 4.
// 5. Gets the minimum and maximum resultant amplitudes for the last plot.
// 6. Click OK to close any error dialog boxes.
//
// NOTE: Because the model is used elsewhere, do not save changes.
