When I import DWG files to a new SOLIDWORKS drawing sheet, lots of layers are imported with the drawing. If I try to copy parts of the drawing to another page, only a few elements of the drawing are copied. I suppose this is because of the layer situation. Is it possible to put everything to one single layer, or, alternatively, how can I copy all elements (located on different layers) of a drawing at once to put it to another sheet, to one single layer? Thanks for your suggestions.
