Everyone: In our detectors we have approx. 500 or so objects that need to be drawn (ranging from wires in wire chambers to phototubes and blocks of a shower counter), instead of have to define each one individually we would like to draw them using a loop (this is also so that in the future it will be easier to modify our geometry). Also, each object needs to be accesible individually (i.e. - wire 4 in the y plane of wire chamber B) so that physics quantitiets can be displayed. However, with the TShapes, what I see is that to do something like SetVisibility, each object must have a unique variable name and to add shapes to a geometry node each object must have a unique name. Now i guess this could be done by having all the shapes stored in an array (takes care of the variable names) and then for the titles of the shapes (i.e. - TBRIK("title"...) we could just make strings over and over again. This however seems a bit too much having to name each object twice. Is there an easier way for doing geometries with many objects. Thanks for any help. Michael Katz-Hyman
