Abstract
A CAD system, method, and computer readable medium. A method includes receiving a graphic model and a selection of a symmetric constraint. The method includes receiving a selection of first and second curves of the graphic model, the selections indicating respective points on the first and second curves. The method includes determining a user's intent and applying a symmetric constraint between the first and second curves according to the user's intent. The method includes storing and displaying graphic model.
Claims21
A method for constraining a graphical model in a CAD system, comprising:
- receiving a graphic model in a CAD system;
- receiving a selection of a symmetric constraint by the CAD system;
- receiving a selection of a first curve of the graphic model by the CAD system, the selection indicating a point on the first curve;
- receiving a selection of a second curve of the graphic model by the CAD system, the selection indicating a point on the second curve;
- determining a user's intent by the CAD system;
- applying a symmetric constraint between the first and second curves, by the CAD system, according to the user's intent;
- and
- storing and displaying graphic model by the CAD system.
A CAD system comprising a processor and accessible memory, the CAD system particularly configured to perform the steps of:
- receiving a graphic model;
- receiving a selection of a symmetric constraint;
- receiving a selection of a first curve of the graphic model, the selection indicating a point on the first curve;
- receiving a selection of a second curve of the graphic model, the selection indicating a point on the second curve;
- determining a user's intent;
- applying a symmetric constraint between the first and second curves according to the user's intent;
- and
- storing and displaying graphic model.
A computer-readable storage medium encoded with computer-executable instructions that, when executed, cause a CAD data processing system to perform the steps of:
- receiving a graphic model;
- receiving a selection of a symmetric constraint;
- receiving a selection of a first curve of the graphic model, the selection indicating a point on the first curve;
- receiving a selection of a second curve of the graphic model, the selection indicating a point on the second curve;
- determining a user's intent;
- applying a symmetric constraint between the first and second curves according to the user's intent;
- and
- storing and displaying graphic model.
