An isolated layer will show only the items on that layer, and hide all
items that are on other layers. Items not on any layer will not be
effected. If an item is on two layers, the isolate status if one layer
trumps both a 'hidden' or 'unhidden' status on any other layers. Also,
FWIW, the 'hidden' status of one layer will trump the 'unhidden' status
of another. That's an overly simple explanation because there are other
things that can affect an item's display. A great (if long) read on
this is at the MCAD central forums, including Glenn Beer's excellent
layers presentation from PTC|User 2007:
