I have an odd artifact in my drawing I can't get rid of. They're actually some crimp pins that should be hidden, but they show up in the drawing. They are not in the boundary box around the drawing view, but move with the view as if they are a part of it. I have removed the display view in the model and remade it, but the pins are still there. If I zoom in to the pins they will disappear after a while. Any ideas?
