Hi, Gabriele. Thanks for the response.

An additional level of verbosity would indeed be welcome. In general, it would be nice to have the option to turn off any, or even all, warning messages (something like the gcc "-Wall" flag). Could this don't-print-warnings-flag be written into the G4Exception class?

The technique I'm suggesting may not be terribly efficient, but all that matters in the end is the time it takes to actually run. I've already put together a very simple (and inefficient) algorithm for finding the smallest bounding sphere on any arbitrary physical volume, and looping over roughly 300 volumes takes a small amount of time, about 4 seconds.

It may be that using CalculateExtent() gives better and faster results, but the difference between 4 seconds and 0 seconds is negligible. If my bounding volume routines grow unwieldy, I'll take a look at CalculateExtent().
