This one might be a doozy…
I’m struggling to create a dynamo script that automates the creation of underground pipes and other objects with MEPover package. It’s supposed to be a crucial part of my Engineer’s Thesis, but at this point I’m at a loss for words, so this might as well be a plea for help. I’m working on a single polyline in the meantime, and the objective is to make it work for the whole area.
Coordinates of the site are large (7 mil x 5 mil) if that might be an issue, and it’s not only one type of utility, there’s electricity, gas, hydronic, water, telecommunications, and sewers.
I know that working with the third dimension of piping might be harder, my current plan is to take polylines from DWG that lacks data for elevation and diameter and import that data from an Excel sheet or a different file (all this data is inside a .dbf shapefile). But if that’s a wrong approach, I’d be more than happy to listen.
With the MEPover package, I’d create a very primitive model using pipes for everything. It’s just to demonstrate that it’s possible and to visualize it.
Below is a snippet of the map
I’ve tried to modify scripts from Create Pipe from DWG - #37 by SPARTAN but it worked only once and the pipe had no diameter.
I can’t select just one element from the DWG link without selecting everything, and I have no idea how I could just take all elements from a set layer, my understanding of Revit is very basic, and I severely overestimated how hard it would be…
If it’s not possible then just tell me I’ll understand and do it by hand

To make life easier maybe you can model a railing element with circle section profile and follow the point heights of the CAD file. Maybe create a topography based on the points and make the railing sit on top of topography. Otherwise you would have to model many broken pieces of pipes with variable start and end points which is a real pain. Nothing is good as solution though
Oh right… I completely forgot to add that CAD file has all elevation values set to 0, so it’s just a 2D map with heights added as a note. One of my thoughts was to add elevation like david_licona did in Go with the Flow in Dynamo
I’m guessing it would be the best for a newbie like me to change the theme from automation to just simply modelling manually since by every attempt I’m starting to further and further realize that I threw myself into a way to deep water without any skills.But the idea of creating topography and using it is interesting so maby I’ll look into it in the future since shapefiles hold height data and could be extracted.
Hi, @wojtslus !
I’ve done similar task. Post your dwg, i’ll try to help.

Hi, is there any reason why you need to do this in Revit and not in Civil 3D where you can also use Dynamo and objects like pipe and pressure networks?

@wojtslus Lets start with welcome to the community!
Personally, I am not a huge fan of modelling things they are not. Often modeling items in other categories is also not allowed by the IDS if there is one.
Maybe you could use this: Creating 3D toposurfaces from imported DWG files in Revit (autodesk.com)
I don’t have experience in Civil 3D. But in Revit you can make pipe systems, you just have to add ore make the pipetype behaver and it’s fittings.
This will make things harder because it isn’t data linked to the objects (lines). Maybe @Vladimir can help you with this.
