         @version 3.02.01 May 30, 2006

         == Subsystem or component described by the file ==
         
         Aluminum base of a blade with a cooling channel (no nipples, no panels). 
         
         == Root volume and its reference frame ==
         
         "PixelForwardBlade"
         
         Y is along the axis of the blade, from narrow to wider end. Once the blade 
         is positioned, its Y axis will be pointing away from the beam line.
         Z is perpendicular to the plane of the blade, pointing from "body" (narrow) to "cover" (wide) side.
         
         == Positioning ==
         
         The file defines AnchorX, AnchorY, and AnchorZ 
         constants that describe the coordinates of the anchor point in the blade 
         root volume (PixelForwardBlade) reference frame.
         Currently, [AnchorX] = [AnchorZ] = 0.
         
         Since the origin of the "blade frame" with respect to which DDPixFwdBlades
         algorithm positions all one-per-blade items coincides with the blade anchor point,
         the "child translation" vector passed to the algorithm should be
         (-[pixfwdBlade:AnchorX], -[pixfwdBlade:AnchorY], -[pixfwdBlade:AnchorZ]).
         
         == Additional comments ==
         
         Blade is implemented so that it consists of 
         "body" (narrow aluminum side), "cover" (wide aluminum side), and
         "tip" (part close to inner ring, common to both sides. 
         Cooling channel then goes into both "body" and "cover".
         
         Multiple boolean operations are used in describing the tip of the blade and
         the crossbar. As a result, IguanaCMS sometimes fails to visualize it properly.
         This seems to be a problem for visualization only, not for tracking at simulation time.
