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.

1. A method for use in a CAD system, comprising:
loading CAD data in a CAD system, the CAD data including a first 2D wireframe geometry and a first 3D feature in a first plane; maintaining, by the CAD system, a first bi-directional logical relationship between the first 2D wireframe geometry and the first 3D feature; receiving an input of a change to the first 3D feature by the CAD system, the change including moving the first 3D feature to a second plane that is different from the first plane; and in response to the input, 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, and storing the changes in the CAD system, wherein making the corresponding change to the first 2D wireframe geometry includes creating a second 2D wireframe geometry, corresponding to the first 2D wireframe geometry, in the second plane, and creating a second bi-directional relationship between the second 2D wireframe geometry and the first 3D feature.
