Modifying sloped piping in Revit - Exercise

In this practice, you are going to change a piping run, so it slopes in the correct direction, using the Slope Editor. You will also connect the sloped pipe to a stack and see how that impacts the ability to change the slope. Finally, you will test the process of modifying the slope of individual pipes.

  1. Open the practice file 001-Small Medical Center-Modify Slope.rvt.
  2. Double-click on the section arrow that points toward the exam rooms. You can see that the sanitary piping is not sloping in this view as shown below.



  3. Make sure that there are only two views open (the Sanitary Plan and section). Type WT (for Window Tile) so they display side by side. Then zoom in as needed.
  4. To change the slope, it is important to select the entire run of pipe that you want to slope. Hover over one section of the pipe and press <Tab> until the entire run is highlighted and then click to select it.
  5. In the Modify | Multi-Select tab, Edit Panel, click Slope.
  6. The Slope Editor displays with options to set the Slope Value and Slope Control Point as shown below.



  7. In the plan view, you can see that there is an arrow on one end of the pipe. This is the direction the slope would go. In the Slope Editor, click Slope Control Point and the arrow switches to the other end of the run of pipe as shown below.



  8. Set the Slope Value to 1/8"/12" and click Finish.
  9. In the section view, you can see that the slope of the pipe is going UP from the Slope Control Point. That is not what is wanted in this case. There is also a warning about an open connection, but we don’t need to worry about that now.



  10. Click Undo to get back to no slope.
  11. Select the entire pipe run and select Slope command again.
  12. Make sure the Slope Control Point is on the end outside the building, set the Slope Value to 1/8"/12", and click Finish. This time the pipe is sloped out and away from the building as shown below.



  13. In the plan view, extend the vertical pipe to the stack just outside the building as shown below.



  14. Select the entire run of pipe that is now connected to the stack.
  15. When you run the Slope command, notice that you can change the slope but you cannot change the Slope Control Point. Sloped pipe always runs down if is connected to a stack.
  16. Press Cancel, as you do not want to change the slope.
  17. In the section view, select the one sanitary pipe running under the exam rooms.
  18. Test out the controls available for individual pipes. When you change the height, it modifies the slope as well.



  19. When working with sloped piping, it is safest to change the overall slope of the pipe run rather than individual segments.
  20. Save the project.
