Editing Pressure Pipe Networks
Before editing a pressure network, it's best to display it in profile view so that you
can analyze your design from more than one perspective. This is done using the
Draw Parts In Profile View command, much as you did with gravity networks.
And just like gravity networks, pressure networks can be edited using four basic
approaches: grips, layout tools, properties, and Pipe Network Vistas. Of these four
approaches, the grips and layout tools approaches differ considerably from how
they are applied in gravity systems. The next two sections explain the details of
how these two approaches are applied to pressure networks.
Editing Pressure Networks using Grips
Grips are a great tool for making quick and simple graphical edits. Civil 3D
provides the following specialized grips for pressure pipes and fittings:
Fitting - Square Grip - Plan view This grip changes the location of the fit-
ting without changing its rotation. As the fitting is moved, the ends of any pipes
that connect to it will move with it.
Fitting - Arrow Grip - Plan view This grip changes the direction of the
fitting by flipping it around the axis of the connecting pipe.
Fitting - Diamond Grip - Plan view This grip slides the fitting along the
pipe it's connected to without changing the rotation angle of the fitting.
