This happens to me all the time.  I will have an assembly and its drawing open and when I call up parts either

from the assembly or the BOM on the drawing my parts will come up with hexigonal type shapes instead of smooth

rounds.  I am constantly having to go into Documetn properties and adjust my image quality that somehow has regressed

back to low, to closer to the high end.  I have actually seen where I keep this part open and toggle to the assembly or the drawing

and go back to the part and it has regressed again.  When I adjust thisin the assembly the part stays ok.  Other times I can

just call up the part and it has regressed again.  Why is this happening?  Does anyone have any answers?

Thank you in advance.
