5// Abstract base class for geometry construction per chamber.

c10e6eaf 10// This Builder is designed according to the enveloppe methode. The basic idea is to be able to allow moves
11// of the slats on the support panels.
12// Those moves can be described with a simple set of parameters. The next step should be now to describe all
13// the slats and their places by a unique
14// class, which would make the SlatBuilder far more compact since now only three parameters can define a slat
15// and its position, like:
2057e0cc 16// * Bool_t rounded_shape_slat
17// * Float_t slat_length
18// * Float_t slat_number or Float_t slat_position

c10e6eaf 91// The code comes directly from what was written in AliMUONv1.cxx before, with modifications concerning
92// the use of Enveloppe method to place the Geant volumes.
93// Now, few changes would allow the creation of a Slat methode where slat could be described by few parameters,
94// and this builder would then be dedicated only to the
2057e0cc 95// placements of the slats. Those modifications could shorten the Station 345 geometry by a non-negligeable factor...
