An improved method of displaying the features of a three-dimensional graphical object model for subsequent selection by a user employs icons in a feature tree which are three-dimensional miniatures derived from the actual features present in the object model that the icon represents. Each 3D miniature corresponds to a specific feature in the object and has a similar, and preferably the same, geometry. Displayed 3D miniatures are shown from a viewpoint and rotation which matches the viewpoint and object rotation used in the graphical window. As the object is rotated, the rotation of the miniatures changes accordingly and as various features in the object are edited, the corresponding miniature is updated accordingly. Actions can also be performed on the miniatures and these actions applied to the corresponding feature in the model. |
