Pressure Pipe Modeling with the Corridor Tools (PART II)

As a follow-up to the post “Pressure Pipe Modeling with the Corridor Tools“ see how to apply a design to your model, how the model updates all the crossings, and how you can project the design pressure pipe onto a road centerline profile.  Check it out after the jump…

    I was under the impression that C3D 2010 was supposed to support full vertical curves in pipe networks. Any idea why that didn’t seem to come to pass? It sure would make things easier than doing a corridor just to draw a pressure pipe pipe in profile.

    I have no idea, but do agree. It would be nice.

    I just improvise, adapt and overcome…

    I sure wish my IT would unblock YouTube….. guess I’ll have to take a look when I get home.

    Mark – Thanks for putting this together! Admittedly I have not made the switch to 2011, but I am sure that nothing has really changed in what you have shown. When making the assembly, could you offset the quadrants to show pipe thickness? Also why did you decide to go this route versus using the subassemblyTrench Pipe 1-3? I did make a post asking the question on autodesk discussion regarding how to use those subassemblies as a assembly however it always wants to create a “right” and not center or left. Regardless, going by the way you are doing it, how would you create a bottom of trench, bedding material, pipe cover, replacement of virgin soil yet at the same time create daylights for various soil type excavation as stated in OSHA’s 1929 Subpart P? This way, I can quantify the amount of soil excavated, the amount of bedding material, amount of spoil return, and amount of hauling offsite.

    @Mark Jung I wish Management would allow IT to unlock YouTube :p

    8 releases of Civil 3D and still no built-in method to design a pressure pipe, or OTB parts for pressure pipes. 🙁

  6. Mark Spatz says:

    With the subassembly trench pipe you can do all that but can you create a surface that represents the pipe to show on other Profiles or Cross Sections?

    That is why we use this method. Simply to show crossings. If we need more we also use the trenching subassembly.

    I imagine you could create some more quads of the pipe to represent the pipe thickness.

    P.S. Don’t feel bad about not using 2011. We are still on 2009 for production but I figured I would use 2011 for posts.

  8. Kevin Oss says:

    Mark – Thank you for the response. I was under the impression that if you used pipe network and created an alignment based on the pipe network itself that the subassembly would take slices from the pipe to whatever surface you were projecting to for your daylight. I am looking at both methods as we speak and appreciate the video tips that you have posted! Keep up the great posts!

    @ Jeremy Nelson, Ha! I hear you, I don’t work with roads at all but work mainly with water and sewer systems. It seems folks like us are the last on the totem pole when it comes to R&D for these matters. On top of that, you have majority of our water and sewer infrastructure that is over 40 years old and are in need of replacement and upgrades. Also we are not just talking large municipals but also small decentralized systems on the small pipe…1, 1.25, 1.5, 2….8-inch clay, copper, galvanized, cast iron, PVC, etc. etc…to me its worth inesting money but then again I am biased.
