There are two types of curve in Mudbox. 3D curves are drawn directly on the surface of a model, and stay with the model as you zoom, tumble, and otherwise change your perspective on the scene. 2D curves are drawn on the view plane (as if drawn on glass in front of your model), and they stay in place as you adjust your view.
Both types of curve can be used to guide sculpt and paint strokes, but only 3D curves on the surface of the model can be used to create a mesh.
You can create curves by drawing freehand with the Create Curve tool, or using a set of pre-defined curve shapes. The curves you draw are primarily used as guides for another operation, either as the basis for creating a new mesh, or to create controlled paint or sculpt strokes.
