During this process, we simplified the layering scheme to uses;2 layer names per feature (road1 and road2, river1 and river2, etc.).;Next we used our Curvefit application to dramatically reduce the size of the;file without making it "jagged".;These maps are supplied ROYALTY FREE, in AutoCAD R12 format, Albers projection.
