After drawings are created in Solidworks 2012, they are then saved as .dwg's and saved into AutoCAD. Mapping is set up to match AutoCAD layers (colours & line types) but when printing they keep coming out in colour. Current AutoCAD setting will print normal Autocad drawings in Black & White but keeps printing the converted Solidworks drawings in colour. Has anyone ever experienced this problem before. Have exhausted all possible solutions besides changing AutoCAD pen settings? Can anyone help please?
