Revit + Civil3D Merger

Revit + Civil3D Merger

I would love to have all of the Revit tools AND all of the Civil3D tools available for site design, in the same model.  In practice, this would probably mean adding all the Civil3D functionality to the Revit engine, though that wouldn't have to be the case.


I want to have massing and objects that exist everywhere (not just in corridors) where I can set quantities, get real earthwork around pipe trenches, and break out soils based on different types of soils (clays, sand backfill, subgrades, bases, etc.) I would love to have EVERY object be a smart object, and get automated quantities of them.  I want to have a "curb" and "sidewalk" and "tree" object to place on a site.  Maybe even get a groundwater table element as well?


I want a model that's shared (or heavily interfaced) with the architects, so they can design a canopy over a site Civil sidewalk, and we can design retaining walls up to the building, and all the footings, pavements, and earth grades show up together in a single model, and sections through the site would show building basements and shells, earth modifications, site paving, and vegetation.


I want site pipe networks that tie into building pipe networks, and I want site power and lighting systems that tie into the building as well.  I want photometric analysis that includes site and building lighting based on the model, and I want it all to be seamless and continually up to date.  While I'm on a roll, I'd also love to have stormwater tools that reliably detect catchment areas and calculate impervious/pervious based on the model too.  Architectural, Structural, and MEP Engineers currently have this.


But Revit as it stands right now can't handle this for Civil and Landscape.  Civil 3D has all the grading tools, the corridor tools, and better sloped pipe tools.  It also has the better interaction to storm analysis programs, and the ability to set alignments and profiles along an alignment (instead of just a straight-line section).  It also has the ability to vertically exaggerate profile views (Revit can only match the vertical and horizontal scales).


Neither Revit or Civil3D really handles traffic signs, pavement markings, and traffic signals well, so I would love to have that functionality added as well.


When the architect asks:  "Can you do the site design in our Revit model?"  I want to say "Yes."  Right now I have to say "No", and work in Civil 3D, and we're both constantly saving down to dwg and exchanging files--and the boundary work between the disciplines is always fuzzy.  Even the pure roadway designers could get value from this--if the bridges, tunnels, retaining walls, lighting design, and roads all shared a model.


So can we do this?  Can we add the Civil3D functionality to Revit, and improve the Site Works functionality?  Can we expand Revit fully to the site?  (Revit Electrical is a relatively recent addition, so there is precedent here.)  Of course I'm imagining Civil3D would live on as a separate program for quite some time like AutoCAD architecture so nobody would lose their software.  I'm also imagining Infraworks could serve as the conceptual partner for this beefed-up Revit, so we'd want good interplay between them.


That's my wish.  Any chance we could get there?  Now that Revit MEP is fairly mature, I would imagine you've got some skilled and talented programmers lying around looking for their next task?


I doubt that we'll ever see (or at least not the forseeable future) the ability to the same type of civil design work in Revit as we normally do in C3D.  But what I DO think is doable and what I DO want which ties in well with this:


My C3D dwg file can REFERENCE the Revit model and correctly show the bldg footprint, correctly show the pipes and electrical connections entering/exiting the bldg.  The C3D Pipe Network would maintain a dynamic connection to the pipe at the bldg (so that if the sewer pipe moves in Revit, the C3D pipe will reflect this change.


The reverse would also hold true.


The C3D data could be directly referenced in Revit.  The Revit model would "know" what the surface looks like and the surface would update when the C3D dwg file is updated.  The Revit model's pipes would change when the C3D Pipe Network is changed.


This would provide the same effect as what you're looking for without requiring a major rewrite of the code.

Just a quick note - to make IdeaStation work well - ideas should be singular in focus.  From Site to Revit to photometrics, and drainage are bit tough to have quality action items from.

But in this case, the idea is specifically related to how the different software packages relate to each other.  Without talking about the Revit, there's no need for this idea.  IMHO, the C3D team needs to collaborate with the Revit team on this one.


Matt.Anderson:  Thanks for replying.  I know it was a huge post--but I guess I'd see that as my final end goal.  As two more short-term action items, I would propose the following as a joint venture of the Civil 3D and Revit teams to make a really awesome product:

1)  Add core Civil 3D functionality to Revit (an easy start would be feature lines, alignments and vertically exaggerated profiles along alignments, then moving to corridors and site utility structures in MEP).

2)  Add full Civil 3D functionality to Revit.

3)  Complete the Revit Civil/Landscape module.


Major downside to this idea: it would more than likely mean the discontinuation of the AutoCAD-based Civil3D.  While some wouldn't mourn this development it would cause severe problems for those non-Revit users who need to reference Civil3D content into their models.  And it would mean existing AutoCAD support techniques would be no longer applicable, requiring those who *only* do civil work to start from scratch in an entirely new ecosystem.


More efficient coordination between the two ecosystems would have much lower impact, and have beneficial side effects of being applicable to vanilla AutoCAD and verticals.



Oh, and "...I would imagine you've got some skilled and talented programmers lying around looking for their next task?".  Not likely.  I can bet there's an action list thats several years old of things they are working on, with Win10 support being very high on it.


Civil 3D and AutoCAD are the past, added them to Revit database system.
