Create Trench Network Structure
Function
This command allows you to create or
modify a trench network structure on a drawing. Before you are able to
locate
the trench structure, the drawing has to be 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. You can locate the trench structure by one of three
methods: picking
points on the drawing, entering the point number, or specifying the
station and offset of a centerline. If you use centerline method, you
need to specify a centerline file. After you locate a point on the
drawing,
you are prompted the Sewer Structure
Data Dialog for entering the sewer
structure information, such as Structure Name, System Name, Symbol
Name, and Elevations. Take a look at the list of the trench points that
have been defined. If there is any point that is connected upstreamly
to the current point, you add it to the Upstream Connections list. The
Invert Elevation and the Pipe Size fields
will be filled with the information of the upstream point. Click
OK to finish entering the trench structure data. The command will
repeatedly ask you to pick a structure point until you hit Enter to finish.
The trench network structure data is saved in a .sew file.
