I am a beginner, probably shows, Question, When zooming in on a part
containing circles or radius the graphic is never a smooth circle, there
will be a command to smooth all these out but I can't find it.
VIEWRES = 2000
When it asks if you want fast zooms, select Y.
Autocad usually has a default setting for viewres of 200. The lower number
speeded up regens and made sense years ago, but with todays computers, a
setting of 2000 works fine. This will take care of most of the jagged
appearance. You will still need to REGEN from time to time.
