AUTOCAD zooming

I recently received a new computer. Still using LDD. When I zoom in on an object, my lines seem to look like arcs and some lines disappear. I am trying to edit the end of a line and when I zoom in I can't get a clear view of everything. Is there a setting somewhere that I need to check?

Try REGEN ALL command. It is the View Menu about 3rd item down.

Also try WHIPTHREAD, check out the options in the Help menu and then try each for a day to see which one you prefer more.

Those options don't affect it at all! Not sure what's going on? Never had this problem before.

Is this a 2D or 3D drawing?

Do you have hardware acceleration enabled or disabled?

Usually people report the opposite problem: arcs and circles looking like they are comprised of line segments.

This is 3D drawing. Where would I find hardware acceleration?

You enter the command -3DCONFIG *enter*

Then L *enter*

Then H *enter*

From there you read what it gives you and find the setting/option you are looking for.

Type VIEWRES at the command line and change the setting to something higher.

VIEWRES: http://docs.autodesk.com/ACD/2010/ENU/AutoCAD%202010%20User%20Documentation/index.html?url=WS1a9193826455f5ffa23ce210c4a30acaf-5250.htm,topicNumber=d0e331503

"...my lines seem to look like arcs..."

If this had read "my arcs look like lines" then I could see where Viewres would be the culprit. Maybe the OP got it backwards?

If it is lines that look like arcs, could it be that the aspect ratio for the resolution on the monitor is set wrong?

Thanks. That seemed to do the trick.
