title: Translation Vector in ElementTransformUtils.CopyElement Revit 2012
body: <p>i'm trying to make Instance of Selected object entered by the user in Revit Api 2012 c#,I discovered that the third input to ElementTransformUtils.CopyElement is the translation vector not the new place so i'm trying to pick fixed point from the element selected then substract the new place location from it and put the result as translation vector.
  the problem is :
  i use pickobject.globalPoint to obtain point  from the selected object  which changes every time i ran the code so 
  the Question : how to obtain the same point every time i select the Element Entered by the user?
  Thanks In Advance </p>
