<!-- Origin of ForwardEMcal is center of upstream face of LGD -->

<!-- Thr Jan 29 08:14:30 EST 2009                                  -->
<!-- changed order of counting columns: 0-58 from south to north   -->

<!-- July 7, 2017, Richard Jones                                   -->
<!-- Added front steel frame and side straps to the LGD blocks.    -->
<!-- Added mylar wrapping around the blocks.                       -->
<!-- Increased the size of the FCAL block unit cell to account for
     the space needed for wrapping, strips, and front frame.       -->
<!-- Added plexiglass sheet (0.5") in front of the LGD.            -->
<!-- Extended the stainless tube around the beam hole to the full 
     length (32.75") shown in the drawings, with front flush with
     the front of the wrapped blocks.                              -->

<!-- July 7, 2017, Richard Jones                                   -->
<!-- Added light cover in front of entrance face to the FCal       -->

<!-- version 2.1, January 8, 2019, Richard Jones                   -->
<!-- Small tweaks to eliminate overlaps between volumnes.          -->
