Now that rhino.io is available for quite some time - is it possible to implement Sweep Nurbs exported from Cinema4D?

I want to do some pipe planning and have the main model setup in MoI.
As there are definitely some revisions to be done and MoI doesn't always behave as expected - is it possible to have the pipes setup in c4d and just the paths and diameters for the extrusions/sweep nurbs exported? if this is exported - do the splines behave as polylines including points or is everything meshed and loads of polygons imported in MoI?



My main concern in MoI is that sometimes it works: model the profile and path spline and afterwards, when adjusting the path the extruded 'pipe' is changing along. BUT this doesn't always happen, no clue why. to avoid running into this and doing the extrusion every time again I wanted to try to model it in Cinema and then just export the extrusion paths..
