For linear dimension between two entities, in which at least one entity is either arc or
        circular edge, you can change the dimension end points. Click the dimension and select
          Change Dimension Endpoints 
         from the context toolbar. You can move the end points using handles(large dots). While
        moving the end points, you can define a minimum, maximum, and center distance between the
        two entities. The dimension value is updated based on the selection or position of the
        handle.
