MI-L Report of Length of Lines and Polylines

[Daryl Riggins]

        I'm constructing a water system map.  Objects are either line or
polyline.  With each object, I have two fields: diameter and material.
I am attempting to determine the total length of water pipe in the map
with relation to the pipe diameter (e.g. total 2-inch pipe=10,000 FT).
Suggestions?
