thanks Zoomer - i moved my model closer to the internal origin - only part of the model became visible when in open gl - then vectorworks stopped working and the program closed.. i can't believe that all my files with 3d geometry are behaving like this - 3 days ago all was working fine.. and i haven't downloaded any updates etc

my whole program is slow and not happy when in 3d mode - when i go to left iso mode my model disappears or is half visible... see the attached - i've tried 6 different files and all are behaving the same.. 

 

i upgraded to vw18 6 days ago but uninstalled it because it wasn't running smoothly and i was in the middle of an important project.. vw17 was running normal till about 24 hours ago...now my vw17 is behaving the same way - 

 

i have checked the unified view tab.. 

 

any ideas???
