From Rhinoceros 4 (T-splines) to SW

Hello,

Today I wanted to put a model I built in Rhinoceros using T-splines to get tested in solidworks' windtunnel. I got the plugin for t-splines in solidworks. There were several things I could do, namely:

Rhino:  -> export selected as .3dm

           -> export selected as .tsm

Then i go to SW t-splines plugin and press open and choose the .tsm file. Then it keeps on saying that there's no body or something How to fix that?

Btw

If I select to export it as .tsm (and had my model exploded) it makes like 60 new files of which i dont know how to bring together in solidworks as you cant open them all together.

How to connect those?

Thank you very much
