You can work with c3d and revit with IFC (highly unussual). Dwg would be an alternative, or nwc as underlay.

Hi,
I just thought (was hoping) they had a better interaction between each other than just IFC.
For the jobs we do there is always some sort of clash coordination btw service and foundations.
The program the civil guys currently use exports IFC files as well but they are absolute rubbish.

Hi, yes you can do some nice things with civil 3d and revit in collaboration.

In theory we should be able to get you a link going.

I have seen this done through dynamo, though my dynamo skills are limited.

There is also a very instructional AU (Autodesk uni) video, I will find it for you and get you the link.

As someone that has pretty much no project knowledge with civil3D I was able to produce a parametric/adaptive tunnel, and get it into revit by following this tutorial in the AU link. (I am a structures guy, and although I've done civil works in my career it was all done with basic vanilla cad) - As civil 3D also has an easy to create and use "profile" Library you can easily do drainage and roadway/gutter profiles etc also in it and bring those into revit using a similar workflow to how it was done in this link.

I had never used civil3D before. Followed a 1 day basic course on it, and the interface is easy to use, and if you use AUTOCAD will have no issues making the transition. In addition, getting topo surfaces done in C3D and bringing them into revit will make your life better also, including all the site works which revit does not currently handle too well even with the site designer plugin.

Anyhow I will find this link for you.

and here we have it

Hi,

Thanks Karalon10 for the link and the input.

For us this is becoming more and more critical depending of the jobs ie be able to coordinate Civil models with drainage, man holes etc with Revit structure (footings, piers).
I have created basic families that I can use to model the pipes and pipe sizes etc – but if all this information already exist in a civil 3d package I would much more prefer to be able to link this information in to Revit.
On some jobs (for shopping centres, service stations etc) the drainage information might change a few times due to council and clients inputs/requests.

At the moment I link in the Civil draftees drawing showing the services into my plans. Depending on the job I will model the pipes but otherwise just use the 2D dwg file as reference to show the locations of pipe work.

Thanks

In that case, IFC will work for importing geometry in most cases.
Personally not a fan of IFC it can be finiky and unreliable, sometimes its smooth sailing and other times you realise it would have been easier to just remodel whatever it is you want to show.

Don't neglect other software like navisworks or solibri which will let you integrate & federate models for clash detection (ie interference with pipes/footings, and consider you can do things like set tolérances. eg if a pipe can not be within 1m of a footing, this rule can be set and checked in those software)

But if you need to show this in documentation its not that much help although I have "heard" that navisworks and revit will soon have a link where you can export a revit readable model from navisworks - which IMO will replace IFC if this is true. Replace isn't quite the right word, I guess I mean the workflow will then become "import IFC geometry to navisworks - export to revit" rather than link IFC directly to revit.

Don't neglect 3D DWG files, these can also be imported in revit, its just an extrusion not much information in it, but it will get your geometry into the project for interference checking. Also its been a while since I did this (2010 or so) but it is possible to use a LISP to extract X,Y,Z values from autocad and use excel as an intermediary to import geometry using an excel file. So if you have a 3D DWG file you can use this to import into revit and set what kind of replacement you want (ie you can map the object type to replace the cad object upon import). I used this technique to import a structural file that had more than 2000 individual sticks of steel in it from excel. It works, but it needed some rework, having said that the process was fairly easy and even with the rework once imported it was quicker than modelling from scratch.

Also ask your surveyor for point clouds file if they have it, is another option and one that revit handles quite well.

Navisworks is handy because it will read almost any kind of file and federate multiple different formats, solibri is a bit more limited in the Spectrum of file types it can use.

I currently work doing a lot of training, and one of my colleagues is a specialist in Civil 3D and other infrastructure programs (Infraworks for example).
Infraworks would not be so interesting for you, it is more for bridges, and large infrastructure road planning etc and in the planning stages, but civil 3D I am convinced will interest you, ask someone local to you for a demo and specifically getting it to talk with Revit - it can, my colleague teaches how to do it, so I know it can be done.

Have you tried this:

Revit to Civil3D via ADSK file.

Civil3D to Revit via export to solid for pipes, etc. and export topo to regions. Described here https://forums.autodesk.com/t5/autoc...e/td-p/4699189


LandXML doesn't work well with Revit.

Karalon10 - That's in Revit 2018 though I've not tried it out myself yet, especially the IFC --> Navisworks --> Revit workflow.

Brisbane, Queensland = 12D.

To be fair, 12D is not your problem. Nor is Civil3D.

If that tunnel video is the one I'm thinking of, its definately not the way you want to run

Don't use Revit for Civil Structures. That's your answer.

thats exactly the point of the question though.
He's not using revit for civil works hes asking if there is a workflow to get the civil works into revit to show with the structure.

I dont agree with you entirely, civil structures are fine in revit, its the topo that causes nightmares.
I've seen bridges done in revit and working no problem (Check out Paul Hellawell of GHD does some nice bridges using revit)


The point is to find a workflow to leverage the civil works done in another program and be able to recouperate it in revit
