My drawings are set to plot by limits. I open a 2002 dwg in 2005 and try to plot, i get this error: Command: _plot The selected layout has an invalid hardcopy configuration. I get the same error if I try to preview. I can switch to window, extents or any other type and it works fine. Even if I re-establish the limits of the drawing it will not work. I have saved my 2000 format drawings to 2004 format first, still wont work. The only way I can plot by limits is if I create a new drawing in 2005 starting with the acad template (acad.dwt), but this doesnt help me with my existing drawings or existing templates created via 2000 format. It seems that limits is corrupteded once it is opened in 2005. Jim
