Beyond the lesson

Beyond the lesson

In this lesson you were introduced to a few basic techniques related to NURBS modeling:

Revolving a curve is the easiest way to create surfaces with radially symmetrical forms— wheels, vases, glasses, pillars, and so on.
NURBS surfaces are webs of interconnected curves. The creation curves are used to create and subsequently modify the surfaces if required.
Proficiency at drawing and editing curves is an important part of NURBS modeling.
The grid is a useful aid for constructing and modifying curves.

Some additional points you should know are:

You cannot render curves, so your work with them is always an adjunct to creating and editing surfaces.
Besides moving a curve’s CVs to alter its shape, you can cut, attach, extend, close, and smooth curves.
After you create a surface from a revolved curve, you can edit the surface at a component level by moving CVs or scaling groups of CVs on that surface to customize the shape of the surface. (You will need to turn off construction history in order to do this.)
