I have a 2" round tube drawn and I can only see the ends of the tube now in model space when viewing a 2d wire frame.  When I switch to a shaded view I can see the entire tube.  Any help would be appreciated!!
 
Thanks,

Type ISOLINES at the command prompt and change the value. The default is normally 4, but for some reason, yours must be set to 0. You will have to REGEN after changing the setting in order to see the change.

THANKS!!!

That was it.  Something caused it to switch from the default setting to 0.
