Hi Matt, I recently endeavored to find a solution for exporting Bim objects to Navisworks & Dwfx which crosses over this posting.
A support case was opened and after a number of questions were asked internally it was closed with the following conclusions.
Export of Civil3d data (pipe networks in this case) to Navisworks / 3dDwfx is limited to only certain object properties and will not export any custom user context information. Some out of the box information is also missing from the export.
Export of Map object data from civil3d objects. Exporting Map data only works from the export Map 2Ddwf when object data is selected, it will only produce information in 2D format only. 3DDwfx files do not produce any Map object data.
Open the Civil3d drawing directly in Navisworks. The same limited Civil3d properties are imported and custom contexts are not included, Map object data is not included.
My conclusion was that for BIM purposes the only real useable solution is to use a program to export the entire civil3d context and part data to a Map object data table then use the 2D DWF through map export to take the custom information to Navisworks but obviously this wont enable Clash detection and is 2d so it's fairly useless for a project working between Revit (A)(S)(MEP) & Civil3d.
Possible short term solution could be to import basic information from the Civil3d exported model then add a new table data in Navisworks for each part from the exported Map object data, this will require a lot of additional custom programming which I am not sure will work yet.
This is some thing which does need to be fixed in both Navisworks, Map3d and also Civil3D in the short term as all of our projects are now BIM and the passing of additional contexts and information is critical to our projects. If this won't work then I suspect I'll be pushed to do drainage designs in Revit (which I do not want to do for obvious reasons)
Also the interaction between Revit and Civil3d needs to be fixed so that all part data & contexts can be imported with a 3d model in revit and also the other way around. The only solution currently is to use 3d Dwg / acis exports to interact.
Rant Over.

Pour Autopiste pour le moment ils viennent d'être formés sur Revit, donc je suppose qu'ils vont trouver le moyen d'intégrer les maquettes de Revit dans Covadis et Autopiste pour la prochaine version.
