TUTORIAL: Create N-sided Patch / surface in Pro/E

TUTORIAL: Create surface using 6 Boundaries (N-sided Patch)

Version: 2001, Wildfire, Wildfire2.0, Wildfire3.0

Most of the surface modeling software needs minimum 4 sided boundaries to create a surface due to the free form surface mathematics - NURBS and Bezier. However, when dealing with 5 sided boundaries and above, designer may required dividing the surface into 2 or more pieces.

Using the Pro/ENGINEER parametric surface modeling tool, you are able to create a surface using 5 or more boundaries. This tool, N-Sided Patch, does not provide surface as flexible as the free form surface but it can provide you the quickest solution.
