I have a few drawings saved as & info has been copied from file to file. The problem is I have lines showing up when plot previewed & plotted. All objects/lines are at 0,0,0. Originally all lines were plines. I have exploded most of the plines, & I do have blocks & an xref. The explosion of the plines fixed a couple of the drawings.
I have come across this before in the past and have forgotten the fix. Any suggestions?
