Parameters
- isSolid
 -  Type:  System Boolean  
Indicates if the Revolution is Solid or Void. 
- profile
 -  Type:  Autodesk.Revit.DB CurveArrArray  
The profile of the newly created revolution. This may contain more than one curve loop. Each loop must be a fully closed curve loop and the loops must not intersect. All loops must lie in the same plane. The loop can be a unbound circle or ellipse, but its geometry will be split in two in order to satisfy requirements for sketches used in extrusions. 
- sketchPlane
 -  Type:  Autodesk.Revit.DB SketchPlane  
The sketch plane for the revolution. The direction of revolution is determined by the normal for the sketch plane. 
- axis
 -  Type:  Autodesk.Revit.DB Line  
The axis of revolution. This axis must lie in the same plane as the curve loops. 
- startAngle
 -  Type:  System Double  
The start angle of Revolution in radians. 
- endAngle
 -  Type:  System Double  
The end angle of Revolution in radians. 
Return Value
If creation was successful the new revolution is returned, otherwise an exception with failure information will be thrown.Remarks
 This method creates an Revolution in a family document. The Revolution will be rotated the plane of the Revolution profile about the Axis.
