Input Trench Line
This command allows you to input a trench sewer network structure
from polylines or points. It first prompts you the Input Trench Line Dialog where you
specify the Trench Type, Trench System, and the System Name. The
Fixed Depth method automatically assigned the trench elevations at
a specified depth from the surface. The Individual Profile option
lets you input one trench reach at a time and save its information
to a profile (.pro). The Connected Network option lets you input
all the trench polylines on the drawing, merge them into a trench
network structure and save the whole structure to a .sew file. For
trenching or utilities without Invert-Ins, uncheck Prompt For
Invert-In Elevation. If you want to set the Rim Elevation to any
surface elevations, check on Default Rim Elev to Surface Elev and
then use the Surface Button to select the desired .tin or .flt
surface file. Prompt For Pipe Wall Thickness allows you to enter in
the pipe thickness that will be used in calculating backfill
quantities in two prompts: 1) the interior pipe size and, 2) the
thickness of the pipe wall. If this is check off, the value in Pipe
Wall Thickness will be automatically added to the Pipe Size for
backfill volumes. You can also enter in a Structure Width to be
considered in the Cut volumes. Pipe Shape determines the prompting
so that you can create Circular, Elliptical, or Rectangular pipe.
Click OK to start inputting trench structures.
There
are two different types of Input Methods in this command: Polyline
or Points. Points allows you to pick freely the location of each
sewer structure. With the polyline method, Takeoff extracts the
coordinates of all the vertices of the polyline to determine the
location of the structures. With both methods you are prompted for
the starting station number. Takeoff computes the station values
based on the starting station number. Next, you are prompted to
enter the Manhole ID (Sewer Trench) or Station ID (Pipe Trench),
Invert Elevation, Manhole Elevation (Sewer Trench), and Pipe Size
or Pipe Group for every station. You can either enter the values
manually or select the texts that represent these values on the
drawing. When you finish inputting a polyline, the command would
ask you for a profile name to store the profile data if you are
doing Individual Profile; otherwise the command would ask you to
pick next polyline that is in the same trench network.
