Abstract
A CAD/CAM system provides a positive indication to a user that the user has located a cursor so that an object on a two-dimensional sketcher plane has been aligned with a point of interest within three-dimensional model geometry, even though the point of interest may not be within the two-dimensional sketcher plane. The object may be snapped to a projection of the point of interest onto a corresponding location on the two-dimensional sketcher plane. Additionally, an association may be defined so that further manipulation of the point of interest on the model within three dimensions will automatically result in corresponding re-location of the object on the two-dimensional sketcher plane. Additionally, to maintain an appropriate relationship among historical data of the CAD/CAM system, interim geometry, which was generated as a result of user actions performed since the user operated on a particular sketch, is removed prior to the user subsequently operating again on the particular sketch. The interim data is replaced with new data generated as a result of the subsequent sketch session.
