Swept blend from Autocad polylines?

I have a series of bridge cross sections (polylines) created in AutoCAD 2013. In Autocad I can easily use the loft function to create a 3D solid from these polylines. Is there a way to import the polylines to Revit and use swept blend or any other command to create a Revit element? Or, if possible, import the Autocad 3D solid and convert that to a Revit element? I've tried to explode the polylines in Revit, but they are all compressed to a single level (all Z-coordinates are lost).


I've found a workaround consisting of creating reference planes at all the polylines and manually picking lines for profiles, but with hundreds of total sections, that's going to be really time consuming...


Any way to solve this? I'm a bit surprised that Autocad and Revit (even though I know they are very different programs) don't communicate better on a "basic line level".
