Add Damper to Motion Study Example (VB.NET)

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.
