You can create surfaces and polygon meshes from curves in several ways.
For information about creating curves to work from, see Curves [Surface and Curve Modeling].
For information about how you can modify the generated polygon meshes and surfaces further, see Deformations, as well as Modeling Polygons & Polygon Meshes [Modeling] and Surfaces [Surface and Curve Modeling],
