Trench Network Quantities
Function
This command calculates the trench
volumes. There has to be a trench network structure that has been
created
beforehand and its data is store in a .sew file whose name is as same
as the drawing name, otherwise you
would get a error message like "Error: no data in sewer network file".
The command loads the trench network data and split them into
individual trench lines and display them on the Calculate Trench
Quantities Dialog. You can choose to calculate the trench volume
of one
trench line or several trench lines at a time. If you select Use Trench
Template for Volumes, you need to Set Trench
Main Template and Subgrade
Template if you have one. If you select
Use Design Surface Profile to Minimize Cut, then the Depth Zones are
depths from the final design surface, otherwise the Depth Zones are
depths from the existing ground surface. If you have Strata Surfaces
defined then the program can calculate cut volumes for a strata you
select. Report Stations Depth Summary will report you your Trench depth
zones by stations along the trench network. Trench Depths can be
reported by either the bottom of the trench or bottom of the pipe by
using the Depth Target pull-down. You can also color the
trench in the drawing by defined zones. Click OK
to compute the
template volumes. Backfill quantities take into account pipe size. A
report would be shown after the calculation.

Prerequisite:
Your drawing is open, has been cleaned
up and pre-processed by such
commands as Define Layer Target, Set Boundary Polyline, Make Existing
Ground Surface and Make
Design Surface. Trench structure data has been stored
in a .sew file, whose name is as same as the drawing name.
