About Creating Pipe Networks From Objects

You can create pipe networks from existing objects in your drawing.

Using this method, you can automatically create a pipe network from entities such as lines, arcs, 2D and 3D polylines, feature lines, or alignments.

The following table lists the types of entities you can use to create pipe networks:

Entity

Description

Line Creates a pipe network from a line that you selected. The pipe network is inserted as a straight pipe with structures at each end.
2D polyline Creates a pipe network from lightweight or heavyweight 2D polylines.
2D spline polyline Creates a series of straight line segments using fit points to define pipe endpoints and structure locations. For more information about fit points, see the AutoCAD Help.
3D polyline Creates a pipe network using vertices in 3D to define pipe endpoints and structure locations.
Arc Creates a pipe network from an arc that you selected. The pipe network is inserted as a curved pipe with structures at each end.
Feature line Creates a pipe network from a feature line.
Alignment Creates a pipe network from an alignment.

You can select objects in the current drawing or from an Xref. You can create a pipe network that includes the types of pipes and structures you specify.

This method of creating a pipe network uses the Pipes and Structures insertion method. You cannot use the Pipes Only or Structures Only insertion mode with this command. If you want to create a single pipe, or a single structure using this command, create the pipe network with pipes and structures, and then delete the desired parts.

Using Vertex Elevations

For 3D entity types, you can select the Use Vertex Elevations option on the Create Pipe Network From Object dialog box. When this option is selected, the elevations of any vertices along the selected entity are used to set the elevations of the pipes created in the network. For 3D entity types, this option determines if the 3D vertex elevations are honored by the pipes created. When checking this option, rules are not applied as they would likely be in conflict with the vertex elevations.

By specifying the Vertex Elevation Reference, you choose the location on the pipe where the vertex elevation is located. The following options are available: Outside Top, Crown, Centerline, Invert, or Outside Bottom. The default is the pipe centerline.

Vertex Elevation Reference = Outside Top
