Abstract: A method is described for editing a graphic object being displayed by an interactive draw graphic system. The method is directed to a rotate edit action on a graphic object that can be selected from a group of individual objects that are being concurrent- ly displayed in an overlaid fashion on the same screen. The method permits the operator to move the cursor that is involved in the object selection task away from the object after the object selection task is completed so that the cursor can be positioned in an uncluttered area of the screen. The direction of movement of the cursor is along the line extending from the center of the object through a point or line segment of the object that was adjacent the cursor the time the object was selected. When cursor motion is under the control of an input device, such as a mouse, the operator's efficiency and accuracy is increased since the desired amount of rotation becomes easier to obtain as the distance between the object and the cursor increases.

Abstract: A technique is disclosed which facilitates the selection by a user of a graphic object on a display screen. Selection is by means of a pointing cursor which is moved about the display screen by means of a pointing device having a select button. When the pointing cursor is brought within a predetermined distance of a graphic object, the point on the graphic object closest to the pointing cursor is higlighted to show the user that that graphic object would be selected if the select button were pressed. If the user presses the select button when a point on a graphic object is highlighted, the entire graphic object is highlighted to indicate that it has been selected.

Abstract: A method for editing sub-objects in an interactive draw graphic application which allows the operator to apply the edit action to the sub-object without affecting the rest of the object. Vertices of the object that are defined by the adjacent common end points of the sub-object are assigned attributes that either permit or prevent the end points from being separated during the sub-object editing process. If the end points are permitted to separate, actual separation is determined by the operator during the sub-object selection action and is based upon whether the point of selection is in the center third of the sub-object or the end third of the sub- object adjacent the vertex to be separated.
