Bezier 2.62 3D Circle

This tutorial is the first in a series on modeling with curves in Blender. Mesh modeling is based on polygons, straight lines connected together to form a face. Most objects occurring in nature (look at the palm of your hand, your face in a mirror, a leaf, or a drop of water), are curvy. Curves indicate naturalness and beauty, such as in a car, a house, or a flower. For example, if we say that a car is “boxy”, that’s a criticism of its straight line, polygonal, design. To make a car conform to our idea of beauty, the design needs some curves. Modeling an object with curves will give it a more natural, organic, look. Part of the problem with mesh modeling is that, no matter how much geometry you define (say for a human face), you’re never going to get the exact, natural shape of the object. Thus the need for modeling with curves.
