Apply Loads to Beam (C#)

This example shows how to apply the total force, or load, along the length of a beam in various types of distributions.

//---------------------------------------------------------------------------
// Preconditions:
// 1. Add the SolidWorks Simulation as an add-in
//    (in SolidWorks, click Tools > Add-ins > SolidWorks Simulation).
// 2. Add a reference to the SolidWorks Simulation interop
//    (in the IDE, click Project > Add Reference > Browse button,
//    navigate to
//    C:\Program Files\SolidWorks Corp\SolidWorks\SolidWorks\api\redist\CLR2,
//    and select SolidWorks.Interop.cosworks.dll).
// 3. Open the Immediate window.
//
// Postconditions:
// 1. Loads are applied to the part, and their
//    distribution types are shown in the Immediate
//    window.
// 2. To verify, examine the External Loads folder
//    in Study 3 in the Simulation tree.
//
// NOTE: Because this part document is used elsewhere,
// do not save any changes when closing it.
