In Creo Parametric 11.0, a new “Extrapolate” method has been added to the Extend feature, offering more control over surface extensions. This method replaces the original surface with a new extrapolated surface that coincides with the original within its domain, resulting in a smoother, less wavy surface extension. The extrapolated surface will have a new Surface ID.

The Extrapolate option is particularly useful when the Same surface extension method fails or creates undesirable results like folding or inflections. It helps produce better outcomes by providing a wider range of geometric extension methods, improving flexibility and productivity.

When using the Extrapolate method, all surface types—except planes—will be extrapolated into a B-Spline or Spline surface. If the original surface is not a Spline or B-Spline, the extrapolated surface will be a close approximation of the original within its domain. Planes will remain unchanged, and for other analytic surfaces, the Same extension method should be used to maintain their analytic nature.
