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. For us a prefix of “zz” means it does not go to clients for others. • Isolates Completed Boundary Either Into Its Own File for Xreference or to be Inserted Into the Primary Drawing. 3.
