Parameters
- aDoc
-  Type:  Autodesk.Revit.DB Document  
 The document.
- dBView
-  Type:  Autodesk.Revit.DB View  
 The view. If it is a 2d view, translation vector must be in the view plane if the element is a view-specific element.
- id
-  Type:  Autodesk.Revit.DB ElementId  
 The element to array. The position of the rotation axis is determined by the center of the element's bounding boxes.
- count
-  Type:  System Int32  
 The number of array members to create. The accepted range is from 3 to 200.
- axis
-  Type:  Autodesk.Revit.DB Line  
 The rotation axis.
- angle
-  Type:  System Double  
 The angle in radians of the rotation.
- anchorMember
-  Type:  Autodesk.Revit.DB ArrayAnchorMember  
 Indicates if the translation vector specifies the location of the second member of the array, or the last member of the array.
Return Value
