DXF is an exchange format for CAD drawings. In pattern making it is the common way to hand a pattern from one program to another.
PatternScan Pro writes DXF in R2013, in millimetres, with curves as polylines and contour, seam allowance, notches and grainline on separate layers. A second AAMA/ASTM export follows the conventions pattern CAD expects.
