I've searched the forum but I can't find a reference to something which is appearing on my AD drawing specifically where after inserted images into a design, each of the images have a purple box around them. Even a rectangle shape has what appears like a border but there's no stroke defined.
I've exported the full design and the boxes don't appear, but it can be a bit of a nuisance when there are multiple boxes overlapping. When I zoom in and out they disappear and then reappear once I come out of zoom. Any ideas?
