Import Splines from 3ds max to use edgesurf

[ampersand]

Hi,

My first post here, as I have been trying to find a work-flow from max to cad and back again.

 

I'm trying to export spline shapes from max, import them into autocad, use the edgesurf function, then export the resulting mesh back into Max.

Can anyone tell me if this is a possible work-flow, and If so some pointers on the process. I can successfully import the splines using dwg, but no way can i find a way to edit them.

My googling turns up nothing but results for Autocad splines to max.

My experience of Autocad is pretty much "0" by the way
