This is perhaps more of a mathematics question than a Mathematica question, but I would appreciate any input. I have defined a function that creates a circle in the XZ plane. I would like to show how this function varies (either parametrically or incrementally) along Y by variations in position and size of the XZ plots. The result should be a tube (or cylinder...) parallel to the Y axis. I can plot a series of circles along Y to show this, but I would prefer to stretch a skin over those circles, i.e., to define a surface. I have examined a couple of MMA tube-plotting notebooks, but these usually involve rotation about one axis to create shells, etc. I would appreciate any references or code fragments. I am a beginner at MMA programming. Dr. Andy R. Bobyarchick Dept. of Geography and Earth Sciences UNC Charlotte Charlotte, NC 28223 <http://anb-mac.uncc.edu>
