Editing Gravity Pipe Networks
As you might guess, the tools for editing pipe networks are even more extensive
than the tools used to create them. This is one reason the recommended way to
approach pipe design is to perform a rough layout and then use the editing tools
to perfect the design. As you're about to learn, Civil 3D provides many ways to edit
pipe networks. In the following sections, the ways to edit pipe networks are pre-
sented in four groups: grips, editing tools, properties, and the Pipe Network Vistas.
Editing Pipe Networks using Grips
Grips are a great tool for making quick and simple graphical edits. Civil 3D
provides the following specialized grips for pipes and structures:
Structure - Square Grip - Plan view This grip changes the location of the
structure without changing its rotation. As a structure is moved, the ends of
any pipes that connect to it move with it.
Structure - Circular Grip - Plan view This grip changes the rotation of the
structure without changing its location.
Structure - top triangular Grip - Profile view This grip changes the
elevation of the top of the structure. Use caution when editing the top of a
structure because, depending on its properties, the software may automatically
reset it to match a surface.
Structure - Bottom triangular Grip - Profile view This grip changes
the elevation of the sump (inside floor) of the structure. This elevation can't be
placed above the invert (bottom of the inside wall) of the lowest incoming pipe.
Pipe Midpoint - triangle Grip - Plan view This grip is used to change the
diameter of a pipe. Dragging it away from the pipe increases the diameter, and
dragging it toward the pipe decreases the diameter. This grip can be used in
conjunction with the AutoCAD Dynamic Input feature to view the diameter or
even type it in.
Pipe Midpoint - Square Grip - Plan view This grip moves the pipe to a
new location without changing its angle or its slope.
Pipe Endpoint - Square Grip - Plan view This grip moves the location of
one end of the pipe while keeping the other end fixed. In profile view, it main-
tains the current elevation of that end of the pipe.
Pipe Endpoint - triangular Grip - Plan view This grip changes the
length of the pipe while maintaining the angle of the pipe and the location
of the opposite end.
