Workflow: Surface to IFC

[Hobbitfoot]

I'm have a scan in cyclone of a surface which needs to be given to the client as an IFC. How do I take either the point cloud or the meshed surface and convert it to some sort of IFC format.
I have tried using civil 3d but the mesh ends up in feet when teated in Revit. The next option was to try Revit but again the object is not a solid so therefore not useable.
Is there a solid export option in cyclone that I'm missing. Normally I would contour the surface and bring those contours into Revit but in this case the vertical surfaces on the mesh make building an accurate surface in Revit impossible. Ideas?

i did some googling and found this

although, a meshed IFC is going to be HUGE in file size.

Thanks. Unfortunately it isn't a 3d solid. A dxf export from Cyclone is a polyface mesh (non-solid) unlike Revit Toposurface which is a solid and therefore can be turned into an IFC as it has mass. If it was a TIN surface (I think) it can be given a thickness but the conversion in C3D won't give me a TIN. There doesn't seem to be a tool which can turn the dxf export into a solid in Civil 3d as the surface is vertically undulating (basically a Cliff face). Its a proper head-scratcher as even a point export wont mesh is C3D or Revit in a realistic fashion. The best I can come up with is a DXF or DWG based on the Cyclone data.

Whilst not to IFC specifically, this session from an old AU class by uber presenter Marcello (he wins top 2 or 3 classes EVERY year!) might be of interest.
