Given a surface in 3-space or scattered points from a surface, we
investigate the problem of deciding whether the data may be fitted
well by a cylindrical surface, a surface of revolution or a
helical surface. Furthermore, we show how to compute an
approximating surface and put special emphasis to basic shapes
used in computer aided design. The algorithms apply methods of
line geometry to the set of surface normals in combination with
techniques of numerical approximation. The presented results
possess applications in reverse engineering and computer aided
manufacturing.
