Pipeline 03

In this exercise, you start the pipeline from the run pipe with a branch and end it at the pump suction connection. You learn how to locate the start point by means of the plane CL (Y coordinate) and a connection point (X and Z coordinate) of the run pipe.

Do the following:

1. Select Piping > Route pipe.

2. Move the cursor between the flanges at the end of the run pipe.

3. Press Q to lock the cursor to the connection.

4. Press Y to define the Y coordinate of the start point.

5. Enter CL+700+2*400 as the value.

   

6. Click OK.

   This time, do not press Space to accept the start point.

   Note: You can also press F11 or Shift+C to lock the cursor to the centerline of the run pipe. That also sets the x and the z coordinates for the branch. It is not necessary to lock the cursor to centerline before branching. However, it is important to move cursor inside the run pipe, and press C to navigate the start point instead of using X, Y, or Z. That is because pressing C locks the cursor but pressing X, Y, or Z does not.

7. Right-click, and select Create branch.

8. Select the run pipe.

   Because the cursor is inside the run pipe, it is highlighted.

9. Press Enter to accept the selection.

10. Enter the values as shown in the picture below.

    

11. Click Done.

12. Set the direction to the negative Z axis in one of the following ways:

    • Right-click, and select Negative Z-axis.

    • Press Alt+Ctrl+Z.

    • Press the Down arrow key and Space.

    

13. Press Shift+A to unlock the cursor.

14. Move the cursor near the second pump suction connection to locate the Z coordinate.

    You have already defined the direction to be parallel to the negative Z axis, so the X and Y coordinates are already defined.

15. Press Q to lock the cursor to the connection.

    

16. Press Space to accept the point.

17. Move the cursor near the end of the pipe.

18. Press W to lock the cursor to the nearest geometry point.

    This ensures that the Y and Z coordinates are the same at the start and the end points of the next pipe segment.

    If you have locked the cursor to a wrong location, press 5 and 6 to release it.

19. Press D to define the relative movement from the end point of the pipe.

20. For dx, enter -400 as the value.

21. Click OK to accept the coordinates.

22. Press Space to accept the point.

    

23. Move the cursor to the direction you want to route the next pipe segment.

    This means that the angle for Fii you set later is already almost correct.

24. Press S to set spherical coordinates.

25. For Radius, enter 400 as the value.

    The segment has to be long enough to have an elbow.

26. For Fii, enter -135 as the value.

27. For Beta, enter 0 as the value, because the pipe passes parallel to the XY plane.

    

28. Click OK.

29. Press Space.

30. Right-click, and select Auto routing method > Normal.

    Now, because there is a flange at the connection point, the direction of the last pipe segment is set according to the direction of that flange.

    

31. Move the cursor near the pump suction connection.

32. Press Q to lock the cursor to the connection.

33. Press P to connect.

34. Click Yes to accept the connection point.

35. Click Yes to accept the pipeline.

    

You have now routed a pipe that starts at the run pipe with a branch and ends at the second pump's suction connection.
