I had a map file set up a few years for mapping the solidworks layers onto the correct layers when opened up in AutoCAD in the correct colours. Since changing over to Solidworks 2013 its worked as normal with the exception on the 0 layer which used to come through as white as it should but now comes through as a dark blue (colour 179). Anyone know why this would have changed. We also upgraded our AutoCAD to 2013 when upgrading solidworks but I can't see how this would have effected things.
