User Interface Location: Click Style > Surface > Options, and then select the Make periodic check box.

Release: Creo Parametric 9.0.0.0

You can now create a periodic loft surface between the selected curve chains using the new Make periodic option.

To enable this option, you need to select three or more curve chains. The surface connects the last selected chain to the first selected chain with G2 curvature continuity. You cannot add reparameterization curves to the periodic surface.

Previously, the quality of lofted surfaces created using closed curves was not G2 at the closure points of the curves.

This enhancement improves productivity and user experience. It reduces the need to create additional surfaces to approximate a closed loft surface with the G2 continuity at the closure points of the curves.
