Add Damper to Motion Study Example (C#)

This example shows how to add a damper to a motion study.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\wrench.sldasm.
// 2. Click View > MotionManager if the MotionStudy tabs are not visible.
// 3. Click Tools > Add-ins > SOLIDWORKS Motion to enable motion analysis.
// 4. Reference the SOLIDWORKS MotionStudy type library.
//
// Postconditions:
// 1. Adds a damper feature, LinearDamper1, between the grips of the wrench.
// 2. Examine the Motion Analysis to verify.
//
// NOTE: Because the assembly is used elsewhere, do not save changes.
