Enhance Selection Intent to Simplify Selection of Edges for Rib,Draft and Blending work ow in NX-CAD Software Development

Abstract

This project is intended to make it easier to Draft and Blend rib structures in a part model. It will implement the ability to easily collect the external edges of a group of faces. 'Curve' Selection Intent will be enhanced to add two new rules: "First Rule" and "Second Rule". "First rule" allows the collection of edges by selecting faces, either directly or by selecting the features that created, modi ed, or collected those faces. Edges that are common to faces selected under this rule will be removed, i.e., all the faces selected are treated as a single face, and the external edges of that single face are selected. The another new rule "Second rule" is essentially the "First rule" with additional edge removal for simplifying the drafting or blending of ribs (or rib-like structures). In this the edges are categorized as Concave and Convex, under this rule major set of convex edges are ultimately collected for the faces selected. Under these new rules, faces can be selected by selecting face-creating features from either the graphics window or the Part Navigator.The 'Curve Collector' block will be modi fied to add the new 'First rule' and 'Second rule' to the other rules that it already o ffers.
