If somebody is curious how both software works together I’ve recorded a short movie. Maybe it will be helpful for somebody. I created a surface with a sweep in Rhino 7 and I’ve created a dynamic link to T-Flex 17. I’ve created a few parametric operations there and I`ve tried to change Rhino surface with parametric operation built over that. All works fine.
Sorry for my chaotic style. This is quite late here and I missed some lines a few times. Cheers!!!
