I have several drawings that someone opened in MEP which should never have happened. The project is strictly ACAD, using Sheet Set Manager. When running publish, there are errors, due to the drawing opening and hitting the dialog box that states it is an MEP drawing.
My concern is that if I open in MEP and export to ACAD 2007, will I lose all of my links to the Sheet Set Manager? What is the best way to go about fixing these files to remove the MEP message and allow publishing to go smoothly again?
