The main purpose of the Curve network is to model complex objects by specifying an intersecting mesh of curves that best describe the intended shape of the model you are building, and the level of continuity to be maintained across boundaries of the surfaces in the network. In addition, you can edit the shape of the surface by interactively manipulating the curves, and observe the effect of these operations on the overall shape of the model. As you modify the network by editing, adding, or deleting curves, the network is updated. Curve networks also provide a mechanism to sculpt or modify the overall shape of the surfaces defined by the intersecting mesh of curves. A special class of curves called sculpt curves are used as extra handles on the shape of the model being constructed.
Sculpt curves provide a very powerful interactive mechanism to achieve complex modeling tasks.
Terminology Before proceeding, you should familiarize yourself with some of the terminology particular to the Curve networks function. A curve is the primary input you provide to the function. Curves can be constructed using any of the existing modeling tools. A vertex is the point of intersection of any two curves . An edge is the part of a curve between any two vertices.
