I am trying to figure out if it is possible to import a 3D surface into Revit Structure, that can be used as a basis for bridge modelling. Does anyone have any ideas as to the best way to do this? I was hoping to use the surface (imported from Civil road design programs) to attach my bridge elements to. I've looked into toposurface, which don't seem to suit my needs, and tried to import the surface into a mass, but have not had any luck. Any ideas would be appreciated.
I am also very keen to use Revit Structure for bridge design, mostly for
flyovers. Currently there is one problem with modelling: Revit does not
allow beams curved in 3D (horisontally + vertically). As vertical
curvature is normally small, we can handle it with straight elements.
Hopefully this will be addressed in next version.
It would be great to reference road and terrain models to Revit or
connect alignment and profile data.
> The 3D road surface has been exported from 12D to Autocad as 3D string lines and as a 3D tin surface. I have tried to create a mass in Revit using both of these but can't achieve what I would like.
> I would like to use the 3D civil design as a reference point that I can base the setout of the bridge upon.
> The bridge has concrete abutments, piles, wing walls, with precast deck units, concrete deck slab & steel or concrete barriers.
I am very interested in this thread and the answers to the previous two questions in particular as I am in the process of evaluating Revit and two other competitor packages for bridge design. More and more of our bridge designs comprise vertical and horizontal curves, usually of precast concrete beams, so this type of complex geometry and interoperability is critical to our software choice.
Any answers to the previos questions or additional information that can be shared would be of great help.
Is there an email address that I can contact you directly? In fact, our product team is currently working with other worldwide customers (who did use Revit Structure to do some bridge projects) to prepare some tutorial/whitepaper type of documentations and share their knowledge with other users.
When it will be ready (very soon), I can certainly let you know and tell you where to download the materials.
