Hi Roger, have you actually run into difficulty with a T-splines model that was just exported as a set of NURBS patches not being acceptable because it made a really large file or something?

I mean, that is actually the main focus of T-splines, to give a sub-d workflow but make a NURBS result...

Did you maybe get something like a client that considered the t-splines output to be unacceptable because it was different from the kind of structure that they were used to?


But yeah if you want to have a final output that is structured like a more typical CAD model, then building it in NURBS from the start would help get you that result... But also for really sculptured / non-2d-profile stuff it will mean operating with a more advanced (and difficult to use, and sometimes kind of headache inducing) kind of toolset instead of the simple solid modeling toolset.

The one you have here is actually not bad at all, but if you start to have broader pieces of the model that you're trying to surface in that way with multiple simultaneous transitions and branching type stuff, all while maintaining high continuity, that's when sub-d/t-splines starts to really become a lot more efficient.
