To Create a Pipe
Before you start to create a pipe feature, reference datum points must already exist.
1. Set the enable_obsoleted_features configuration option to yes to make the Pipe command available on the All Commands list.
2. Add the Pipe command to the desired user-defined group on the ribbon.
* 
For information about customizing the ribbon, see the Related Links.
3. Click Pipe. The OPTIONS menu appears.
4. Click one command from each of the following command sets:
Geometry—Create a pipe feature with a hollow or solid geometry.
No geometry—Create the pipe trajectory only.
Hollow—Create a hollow pipe with a specified wall thickness.
Solid—Create a pipe with solid geometry (a rod).
Constant Rad—The bend radius for all arc segments of the pipe will be the same.
Multiple Rad—The bend radius for each arc segment is specified and can be modified separately.
5. Click Done.
6. If you selected Hollow, type the values for the outside diameter and wall thickness. The CONNECT TYPE menu appears. Use the commands on the CONNECT TYPE menu to add, delete, and insert points to redefine a pipe trajectory, as well as specify tangency to a linear trajectory.
7. You can create the pipe trajectory by connecting the datum points. One of the CONNECT TYPE menu commands can be used interchangeably on the same pipe to construct the trajectory. The commands are as follow:
Spline—Create the trajectory as a three-dimensional spline passing through the datum points.
Single Rad—Create the trajectory by connecting datum points with alternating straight lines and arcs with a constant radius, starting and ending with straight lines. The datum points are connected with straight lines, then the breakpoints are filleted with the arcs of the specified bend radius.
Multiple Rad—Create the trajectory by connecting datum points with alternating straight lines and arcs with a variable radius, starting and ending with straight lines. The datum points are connected with straight lines, then the breakpoints are filleted with the arcs of the specified bend radii.
You can connect datum points in a datum point array using one of the CONNECT TYPE menu commands:
Single Point—Select individual datum points. These points can have been created individually or as part of a datum point array.
Whole Array—Connect in consecutive order all the points in a datum point array.
8. You can add, delete, or insert points while creating or redefining the pipe feature using the following commands:
Add Point—Add to the definition of the curve an existing point, vertex, or curve end through which the curve will pass.
Delete Point—Delete from the definition of the curve an existing point, vertex, or curve end through which the curve currently passes.
Insert Point—Insert a point between already selected points, vertices, and curve ends. This modifies the curve definition to pass through the inserted point. The system prompts you to select a point or vertex before which to insert.
9. Use one of the techniques below to complete the creation of the pipe trajectory, depending on the command you chose:
Spline—Start clicking points; the system connects them with a spline.
Single Rad—After you have selected the third datum point of the trajectory, you are prompted to enter a bend radius value. The system uses this radius for all the other bends in the current pipe feature.
Multiple Rad—You are prompted to enter a radius value for each bend defined by three consecutive points. The SEL VALUE menu lists all the existing radius values for this pipe. Either select one of the listed values, or choose the New Value option and enter the new value.
Spline—(alternating with either Single Rad or Multiple Rad)—Create a trajectory for the first option, then the other. Connect the trajectory points accordingly.

As you select datum points, the system constructs segments of the pipe feature. If a segment cannot be constructed, the system ignores the last datum point selection.
10. When you have finished creating the trajectory, choose Done.
