Pipes in no-mans land

Have you ever laid your pipe network down only to find out later you’ve made a grievous error? Check out one of many solutions after the jump.

It all became very obvious after I selected the ‘draw parts in profile’. The pipes and structures are waaaay down in no-mans land.


So doing a little investigative work (right-clicking on a pipe and selecting Pipe Properties, then selecting the Part Properties tab), I had my first AHA moment – I forgot to select the proper surface and alignment for this pipe run!


My choices are:

  1. Erase and redo the pipe run with the proper surface and alignment
  2. Modify the pipes and structures so that they have the proper surface and alignment

In this case, I opted to modify the pipes and structures. I did thins by clicking on the reference surface and alignment and select the proper values – for this example, Road B is what I want.

After doing this I had the WTH (what the heck) moment. The structures are back where they should be, but the pipes remain in no-mans land.



So after scratching my head and wondering why in the world I would have chosen the choice to edit the pipes and structures, I came upon another AHA moment. I right-clicked on a pipe and selected ‘Apply Rules’. AHA! Now the pipe are back up and I can modify them a bit better.

back home

How did this all work? Since I had pipe rules set, when I hit apply rules, it re-evaluated the pipe and based on the rules, moved it back up to meet the criteria.

After I discovered this method, fixing my errors was a lot easier. Hope it also helps you.

    Don’t forget one can also modify the rules to let one know when a surface is not present and allow the user to enter an invert elevation to prevent the no-man lands situation: http://www.civil3d.com/2007/11/modifying-cover-and-slope-rule/
    The steps are a bit different for the newer .net pipe rules though, but the concepts are the same.
