Differentiate Into Layers & Notes • Allows Technicians to Plot Deeds & Maps While Important Boundary Items Are Noted for the Surveyor’s Use. • Makes the Resulting Line Work Easy to Separate From Text. • Keeps a Record of Exactly the Calls in the Deed (e.g. static labels for bearings & deed). 1.

Separate Boundary Drawing • Keeps All Notes and Plots Together in one File for Reference. • Keeps Internal Comments & “Proprietary” Analysis In-House.
