We currently utilize AutoCAD for our mine mapping purposes. I recently had a seismic study performed to determine the top of salt. I asked for a .dwg file of the contours that were developed. The .dwg file they provided does not have our autoCAD map on it. They are simply contour lines. These contour lines, however, have the same coordinate system as our mine map. The surveyor and I provided coordinate data to the company to develop the contour lines. I would like to lay these contours into our mine map. How do I import the contour .dwg file into our mine map file so that they lay exactly where they should?
