Dynamo To Speedform

I am generating a TSpline mesh in Dynamo.

There are some little details/artifacts I would like to fix in a few corners of the mesh.

It would be very complicated to fix them in the Dynamo definition.

it would be very easy to direct model the mesh to fix those defects manually in SpeedForm once the right paramenters have been found.

Is there a way to export the TSpline from Dynamo to SpeedForm?

Another way would be to export the lines that define the non smoothed TSpline Cage in Alias, then bring the modified Cage in SpeedForm (from Alias) to recreate the TSpline with something similar to TSplineSurface.BuildFromLines.
When I import the modified Cage lines back in Dynamo (from Alias) and use TSplineSurface.BuildFromLines Dynamo struggles a lot to digest it and for instance fails to apply TSplineSurface.BevelEdges (while the orginal mesh was digested fine). That is why I have been forced to think of SpeedForm.

Thanks in advance for any help

Have you tried any of the TSplineSurface.ExportToTSS/TSM and the equivalent import nodes?

pity me, I thought there was not.

It works great.

I am now thinking to select TSpline cage edges based on how close they are on a surface, do you think it would work in Dynamo?
