    Tim,

  I was trying to understand the datastructures in magic, i.e how 
objects (diff layers) in a cell are stored in magic.

This is my understanding 

  The current Cell to be edited will be pointed EditCellUse.
  EditCellUse->cu_def data structure will have all the cell definitions (for
all layers).
  EditCellUse->cu_def->cd_planes (of type Planes) has all definitions for
each plane.
  But my doubt is, to define a Object a Tile Struct will do. Why are four
tiles used to define
  a Plane and also each plane (i.e layer) can have more than one object. How
is this represented 
  in magic. I was unable to understand the documentation in source code. Can
you help me out.

Kamalesh V
