Hi, Newbie to Vectoroworks here - I just started having this problem yesterday and can't seem to get rid of it. A thick black line is appearing around all my lines, and only disappears once in wireframe mode (or when I am moving around the page). Can't seem to find any advice with these keywords (or know what it is that I should search for!) Wondering if anyone has any advice how to get this back to normal so I can see my lines again? Many thanks! Annie
