Hi Roger,

Yeah, there are definitely cases where a sub-d modeling toolset like you find in Modo or T-splines is easier for a particular case than a NURBS modeling toolset.

If you find yourself worrying a lot about continuity and trying to make a patchwork of surfaces smooth to one another, that's generally a sign that a sub-d modeling toolset could be a better fit for that particular model than a NURBS modeling toolset.

Really the area where a NURBS modeling toolset becomes particularly strong are when the models are well defined by profile curves so you can do things like cut a solid by a profile curve and shape your model by boolean combinations possibly followed by fillets rather than going in a "patch by patch" type approach like you were trying in this case.


But it is not unusual that certain kinds of models will be better for sub-d and that other kinds of models will be better for NURBS. There is not one single kind of modeling technology that is universally better for every single kind of modeling task. It sounds like that is kind of what you are hoping to find? But that is just not something that exists.

Maybe in your case here it would be possible to do more of a boolean + fillet approach instead though, I'll take a look at your model which I have not examined closely yet.
