ContextCapture 3MX mesh file into terrain modeler

Question

Hello, I'm currently working with contextCapture and 3mx files directly into the PowerCivil SS4. At this moment we have a mining project that require some work with surfaces for model platforms and roads into PowerCivil, and also for design a complete workflow from the capture of spatial information data from UAV to the final civil products delivered by PowerCivil. 
 I can see and manage the 3mx file into PowerCivil, but I can't model any surface with it... it is posible to manage this file without any transformation into the Openroads technology? 
 
 Thanks for your help, regards.

To the best of my knowledge, you cannot change the 3MX format to create PowerCivil surfaces from it. 
However, what I have done is to create a new production in ContextCapture and save it in OBJ format. I can then save the OBJ as DGN format. The resultant mesh can be manipulated using MicroStation tools, and a terrain created from it in PowerCivil. 
Note however, that the terrain element does not allow overhanging regions, so you will not get the same surface in these regions.
