Yes! For the first time I managed to create a shoe-last with a footscan as a reference, with more or less the same workflow as I did with T-Splines.
I am very happy to see that Sub-D is in progress again, because I am still dependend of T-Splines for my work as an orthopaedic last designer and sofar I could not find good alternatives.
I still am missing features in Rhino that I use now with T-Splines, but the essential functionality is here now.
I can pull (mesh) points to a foot-scan (= a mesh), insert edges using retopo pull,and use my favorite control object as a control cage.
It would be great that when transforming a mesh to SubD the original mesh would still be available as the control mesh ( In the first releases of Sub-D this was an option as I remember it). That would allow
me to pull meshpoints to an object an see in real time the SubD made from this mesh follow the deformation of the mesh. Also for Cage edit.
Anyway, It seems that I can keep using Rhino for my work in the future, now Sub-D is being under developement again and that makes me very happy!
