Abstract: A software control method includes forming groups of software application functions. A different characteristic is associated with each of the groups, and a different graphical user interface (GUI) object is formed for each function in each of the groups. Each GUI object includes the characteristic associated with its function's group and a second characteristic that distinguishes its function from other functions within its function's group. A computer program residing on a computer-readable medium includes instructions for causing a computer to form a different graphical user interface (GUI) object for each of a collection of software functions. Each GUI object may include a first visual characteristic that identifies a first characteristic of the object's associated function, and a second visual characteristic that identifies a second characteristic of the object's associated function.

Abstract: The invention provides generally a method and system for selecting an element of a computer generated drawing model graphically represented on a computer screen wherein each selectable element of the model occupies a position in a hierarchical tree describing the model. A pointer can be used to specify a position on the screen and pre-selecting an element on an axis extending from the position of the pointer along a predetermined direction such that the direction is not in the plane of the screen. Pre-selection can be moved from a first position on the hierarchical tree to a second position on the hierarchical tree in response to activation of an arrow mechanism. Full selection can be accomplished by activating a selection mechanism.

Abstract: A method and apparatus for controlling shadow geometry on a computer display in an interactive computer display system. The method and apparatus comprises: maintaining primary element information defining a primary element; generating shadow geometry information defining a shadow geometry, the shadow geometry information having a predetermined mathematical relationship with the primary element, the shadow geometry information being generated in response to user manipulation of the primary element; integrating the shadow geometry with the primary element to form a single graphical unit (called a "par"); and selectively displaying the secondary element concurrently with the primary element.

Abstract: A computer-aided design and drawing system having a dynamically oriented compass cursor is disclosed. In the interactive computer-controlled drawing system, a method and apparatus is disclosed for automatically generating and manipulating a dynamic compass cursor. The method comprises the steps of: 1) generating a compass cursor in a first orientation, the compass cursor being responsive to movement of a cursor control device; 2) selecting a geometrical element having a second orientation; and 3) selectively re-orienting the compass to the second orientation and maintaining the second orientation until a new orientation for the dynamic compass cursor is selected.
