Alias is a NURBS (Non-Uniform Rational B-Splines) surface modeler. Learning to model with NURBS geometry is like learning to model with any physical or digital medium: you need to understand how the material behaves and how to manipulate it to achieve the desired shape.
This section does not teach you how to model in Alias, but does provide you with a few introductory concepts on techniques. To learn how to effectively model in Alias, take advantage of the Alias learning material and the rest of the on-line documentation.
