TUTORIAL: Create Boundary Blend Surface with 3 Boundaries in Pro/E Wildfire

Version: ProE Wildfire, Wildfire 2.0, Wildfire3.0, Wildfire 4.0

Boundary blend is one of the advanced surface features (parametric surface) in Pro/ENGINEER. Boundary blend feature can be created from 2 boundaries / curves and onwards. This tutorial walks you thru the steps on how to create a boundary blend quilt / surface for 3 boundaries in Pro/ENGINEER Wildfire.

 ProE Boundary Blend tutorial intro

Download the ProE part file used in the following boundary blend tutorial here (ProE boundary blend with 3 boundaries file).

 ** Sometime boundary can form a surface with 3 curves but sometime it needs 3 curves and 1 point. It depends on the geometry and also the Pro/E version & datecode. For my observation, Pro/E Wildfire 3.0 and Wildfire 4.0 can do a better job when we deal with boundary blend tool.
