Abstract: A technique is provided the user of an interactive computer graphics application which allows the user to attach lines to objects such that when the objects move, the lines will rubberband to follow the object. The objects are provided with an attribute that describes their "stickiness". If an object is given the "sticky" attribute, then lines which touch or overlay the object will rubber-band to follow the object's movement. It is also possible to provide end points of lines with the "sticky" attribute so that the end points of lines can be attached to objects. Further, objects of arbitrary geometric shape can be attached to other objects of arbitrary geometric shape using the "sticky" attribute. The feature facilitates editing and revision of graphic files.

Abstract: A method of, and system for, accurately manipulating objects on a screen to obtain a desired layout. Objects are called or built and then manipulated in terms of rotation and or displacement. Accurate manipulation is facilitated by displaying a readout of the extent of rotation and/or displacement. Upon obtaining a desired layout, the layout is stored, printed, used to drive a process, etc.

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 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.
