Random lines showing when converting to PDF

[Anonymous]

I am very new to AutoCAD so any help would be much appreciated.  When converting drawings to PDF random lines show up connecting holes to holes.  These lines do not exist and were not drawn in the model.  The drawing is of a store's countertops and the issues are on the right side of the drawing on top of the countertops.

When I zoom in closer the lines disappear.

Hi,

On the command line in AutoCAD, type  LINESMOOTHING and set it to  Off (0). You can also enter the  GRAPHICSCONFIG command and disable the "Smooth line display" checkbox.

Turning off hardware acceleration completely can also prevent unwanted line work from showing.
