Surfaces are a type of geometry with zero thickness. To create surfaces, you use many of the same methods used to create solids, such as extrudes, revolves, and sweeps. Surfaces also use other functions or features such as trim, untrim, extend, and knit.
Surfaces have advantages over solids. They are more flexible than solids
because you do not have to define the boundaries between the surfaces until the final
steps of the design. This flexibility helps product designers work with smooth, extended
curves such as those used in automobile fenders or telephone housings.
In this lesson, you start with an existing sketch composed of lines, arcs,
splines, and sketch points. Then you apply the following surface features to create a
nozzle:
