Input Trench From Polyline
Function
This command allows you to input a
trench sewer network structure from polylines. It first prompts you the
Input Trench from Polyline Dialog
where you specify the Trench Type, Trench System, and the System Name.
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 tenching 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. Click OK to start inputting trench structure.
Pick a polyline that represents a trench reach on your drawing. Takeoff
extracts the coordinates of all the vertices of the polyline and
prompts you for the starting
station number. Takeoff would computer 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 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.
