export modeling c3d to revit

[emanuele ranucci]

thank you in advance for your availability.
I have the need to export objects (travelling and roads) made with the civil modeler to revit. I'm using the 'extreme modeler' command in a new file that then matters on revit via 'importa cad', I would have two questions.
- how can I make the imported file coincide (same xyz position) on revit and civil 3d?
- for necessity of future rendering and application materials I would need the imported instance to be differentiated, for example the rails of the railway differ from the massive, how can it be done?
currently the imported file appears as a unique entity to which it is not possible to assign a material from revit

- for the first question you can use this free addin on your autodesk account:

- for the second question you have to play with the layers and assign the materials according to the layer (from objects styles > imported objects)

 

[emanuele ranucci]

unfortunately does not separate me the elements of the component used for the modeler of civilization, there is another method? Maybe importing the object as a generic model?

 

[Tristan]

created 3d solids from the modeler? You can't pass the modeler directly. revit is not able to handle it!

 

[emanuele ranucci]

Yes, I created solids and exported to a new civil paper that I then imported into revit

 

[Tristan]

then you should have a layer for each subassembly of the modeler, if you exported it correctly. How's the section like that?

 

[emanuele ranucci]

I attach a photo, perhaps the problem is that the subassembly is a unique block with different parameters to be able to manage (type of rail, massive, etc...). However creating and selecting the solid in civil you can interact element by element, which in revit is not possible.
Annex 1
Annex 2 solid on civil

 

[Tristan]

it is also possible in revit, but the question is too complex to be dealt with on a forum

 

[emanuele ranucci]

Can you tell me what's the easiest way to solve my problem?

 

[Tristan]

I'm sorry to tell you, but your problem doesn't have a simple solution.

 

[emanuele ranucci]

if once the work in civil 3d exported topography apart (without works) and, in the same way railway and street as ifc objects to import on revit, would solids maintain their division?
Thank you.

 

[Tristan]

this depends on how to export the ifc file...and anyway, in revit you can't currently connect the ifc files according to the shared coordinates, so you should georeferencing the hand model (which is very complex in revit if you need a good precision)

 

[emanuele ranucci]

I have searched for some solutions on the internet, I believe that the solution you were referring to concerns the use of civilconnector and therefore dynamo scripts for the creation of the solid in revit starting from a file of excel points of the base line starting from the object made in civil. I would like to know if the procedure is feasible so as to start following this path. I link the videos I want to follow, can you tell me if it's the right solution? Thank you.

 

[Tristan]

starting from the assumption that I never managed to bring anything other than points from civil3d to revit through civilconnection (but I realized if the problem was mine or the package, but in the various forums of dynamo I saw that I was not the only one to stumble into that question), until data exchange will not be operational, the most effective (and at the same time more messed up) is dynamo.
but if you take this path prepare a good dose of patience (and blasphemies)

 

[emanuele ranucci]

from what I see data exchange seems to be available in beta test, did you try it?
ps: regarding the use of dynamo I realized that the procedure is divided substantially into 2 phases: export of the points of the tracked by c3d and 'sweep' of an adaptive family of revit on the same. for the creation of the family is enough to follow the usual logic of creation of families in revit right?

Not yet, I just saw some footage.

si giusto.
