Into ECAL Logical Volume were installed :
Inner and Middle Modules into ECAL Inner and Outer Sections
Simplified Inner Support Frame into the center
Outer Section contains too many modules
2Dim paramphysvol is needed

Inner Assembly Stack :
2 Plastic Layers
2 Steel Pressing Matrixes
4 Steel Stretching Tapes
66 Pb Plates
67 Sc Plates

““Subtraction&Rotation”Subtraction&Rotation” problem problem : : Subtraction = Solid1-Solid2 Subtraction = Solid1-Solid2 Solid2 rotates without any request,Solid2 rotates without any request, may be may be “Rotation Memory”? “Rotation Memory”? If fix If fix Solid2_Rotation=0Solid2_Rotation=0 and exclude other Sub Detectors: Solid2 and exclude other Sub Detectors: Solid2 rotation disappears…rotation disappears…
