Hi dejule,

> Is it important to build surfaces with single span curves?

Not necessarily... It totally depends on what your goal is and what you are trying to do.

Many kinds of primitive surfaces for example a sphere or a cylinder are made up of surfaces made up of multiple spans.

Just having multiple spans does not in itself automatically mean there is a problem.


There really isn't a good answer to your question without putting it in some more context - what are you intending to do with these surfaces, what is their final goal, are they going to be turned into polygons or sliced into sections for manufacturing that will render any worries about super high degrees of continuity to be meaningless?

Is there some particular problem with multiple span curves that you are trying to avoid?
