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.

A method for editing a sub-object of a graphic object displayed in an interactive draw graphic system in which said object has at least one vertex and a pair of selectable line segment sub-objects which define said vertex, said method including the steps of; (a) assigning to said vertex an attribute

A method for editing a sub-object of a graphic object displayed in an interactive draw graphic system in which said object has at least one vertex and a pair of selectable line segment sub-objects which define said vertex, said method including the steps of; (a) assigning to said vertex an attribute which permits said vertex to ‘break’during a sub-object editing action, (b) selecting said line segment sub-object at a different point along the length of said line segment depending upon the modification desired on said sub-object, and (c) moving said sub-object selected in step b) to obtain said desired modification.
