Ian, If you need the mass properties of the spring under varying conditions, you might still be able to approximate it with AME close enough for your specifications. Of course the best approach would be to sweep a circle along a path but AME will need to support NURBs before we can offer that capability. I personally am not familiar with any API products currently available although I expect a number of developers are working on applications. You might want to contact the following companies for information: Swanson Analysis Systems, Inc P.O. Box 65 Houston, PA 15342-0065 Engineering Technology Associates, Inc. 1100 E.
