CAD SYSTEM AND METHOD FOR WIREFRAME COUPLING

摘要

Methods for use in a CAD system. One method includes loading CAD data, the CAD data including a first 2D wireframe geometry and a first 3D feature. The method also includes maintaining a first bi-directional logical relationship between the first 2D wireframe geometry and the first 3D feature and receiving an input of a change to the first 3D feature by the CAD system. The method also includes making the change to the first 3D feature and a corresponding change to the first 2D wireframe geometry by the CAD system using the first bi-directional logical relationship, in response to the input, and storing the changes. CAD systems and computer-readable mediums are also discussed
