You can create pipe networks from existing objects in your drawing.
Using this method, you can automatically create a pipe network from elements such as lines, arcs, 2D and 3D polylines, feature lines, or alignments.
The following table lists the types of elements you can use to create pipe networks:
|
Element |
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 Levels
For 3D element types, you can select the Use Vertex Levels option on the Create Pipe Network From Object dialog box. When this option is selected, the levels of any vertices along the selected element are used to set the levels of the pipes created in the network. For 3D element types, this option determines if the 3D vertex levels are honored by the pipes created. When checking this option, rules are not applied as they would likely be in conflict with the vertex levels.
By specifying the Vertex Level Reference, you choose the location on the pipe where the vertex level is located. The following options are available: Outside Top, Crown, Centerline, Invert, or Outside Bottom. The default is the pipe centerline.
Vertex Level Reference = Outside Top
