Convert polyline into NURBS curves

Is there any way of automating a conversion of polylines in Rhino to NURBS curves? At the moment the lines are made up of small (sometimes very small) straight line segments. This cause some problems with meshing later. What I am after is a single curves which can’t be exploded into smaller segments and at the same time follows closely the original lines.

Thanks in advance

Hello - I think FitCrv is what you are looking for. Possibly Rebuild, it depends on what your goal is…


That’s perfect. I was after Rebuild. I was able to select all the curves and do it with one click! Amazing

Thank you!
