00:09There are two types of pipe networks that can be designed using Civil 3D.
00:15Pressure pipe networks are used to model distribution systems under pressure,
00:20such as gas and water supply.
00:22Pipe networks, which we will describe here,
00:25are used to model gravity systems, such as storm and foul water drainage.
00:31Pipe networks are created using two types of objects or domains.
00:35There are pipes, different shapes and materials,
00:40and structures, such as a headwall, manhole or gully.
00:47There are no pipe bends or fittings, and the pipes run directly between the structures.
00:54To design these networks, we first lay out the route in plan,
00:57with the structures placed on a surface, and pipes are placed below the surface using some simple rules.
01:04This creates the network in 3D.
01:08We can draw the pipes in a profile view that allows us to easily adjust the pipe elevations and slopes.
01:17These objects are provided in a catalogue of components and can be customised or new parts created using the Part
01:24Builder tool in Civil 3D.
01:27The Part Builder allows you to create a parametric part with variable sizes that can adapt to design considerations such
01:35as pipe depths.
01:37Some structure types can be shared with Infraworks and are created outside of Civil 3D using an application called the
01:44Infrastructure Parts Editor.
01:47Structures created with the Infrastructure Parts Editor are modular and can combine different surface structures, underground structures and covers or
01:55grates to create a part family with different sizes assigned.
02:01Each catalogue is divided into part types, part shapes and families.
02:07The part families are the individual parametric components that we use in our models and can have a range of
02:13sizes assigned to them.
02:15To access a structure or pipe in your drawing, you must first set the catalogues you wish to use.
02:22A standard catalogue for both metric and imperial structures and pipes is installed with Civil 3D, and additional catalogues may
02:30be installed as part of a country kit.
02:33To work on a model with pipe networks, you must have access to the same parts in the catalogue that
02:39was used to create the network,
02:41and so the catalogues are often copied to a central server or project folder to provide access for the entire
02:48project team.
02:49There are separate catalogues for pipes and structures, but both must be accessed from the same location.
02:58You cannot directly insert a part from the catalogue into a model.
03:02To provide access to a part family, you must first create what is called a parts list.
03:07The parts list references specific sizes of families from the catalogue and is saved in your drawing.
03:14We create a parts list using the pipe network settings and choose the families such as manhole types and pipe
03:21materials and sizes that we want to use in the project.
