I have a application that needs a curved surface. It'srevolved from a high order polynomial, let's say 4th order. Can I do this with Pro/E? the function should like this y = a * r^4 + b* r^3 + c*r^2 + d*r + e, wherea, b, c, d and e are all constants, and r is the radial coordinates. Any hints are welcome! Thanks
