Abstract: PROBLEM TO BE SOLVED: To provide a method and system for generating a path to be traced by a cutting tool in a milling cut situation. SOLUTION: A new shape concept called a 'focal area' suitable for a milling cut situation is used so that a fixed contact with materials to be cut can be held by a cutting tool, and that a tool path minimizing the abrasion of the tool and an impact load can be generated. Moreover, the tool path is optimized so that the short path can traced, and the cutting time can be shortened. This tool path generator is suitable especially for a high speed slice cutting application.

Abstract: PROBLEM TO BE SOLVED: To provide a system, a method, and a device for forming a visual tool showing correspondence of the same part of a drawing for a certain object between all views of the part in the drawing. SOLUTION: In this method and system for assisting a user in recognition of a element of the object inside various views shown on the object drawing, a selected side of the object in each view is automatically displayed in enhanced form, while the sides of respective planes adjacent to the selected side can be independently displayed in enhanced form. This process facilitates user's recognition of the three-dimensional shape of the object. This invention is suitable for computer assisting designing, computer assisting manufacturing, and computer assisting engineering especially.

Abstract: PROBLEM TO BE SOLVED: To prepare a drawing path for satisfying an accurate standard from the drawing path (route) lacking a precise standard plotted by a drafting indicator. SOLUTION: This method is provided with a process for generating the group of indicator information elements for indicating the moving position of an indicator within the path lacking a prescribed precise standard, the process for generating the group of converted information elements for indicating a position in response to the indicator information elements, the process for adding an arithmetic operation to the converted group of the information elements by using a neural net and classifying the converted group in response to the arithmetic operation, the process for generating the feature of the group of the indicator information elements in response to classification and the process for determining the changed group of the information elements for indicating the position of a changed path not lacking the precise standard.

Abstract: A system simplifies a geometric model to accelerate the rendering of the geometric model. A surface description of the geometric model is stored in one or more of the system memories. A wire-frame description of the geometric model is also stored. A surface simplification process alters the surface description to create an approximation of the original surface description. A wire-frame draping process drapes the wire-frame description onto the simplified surface and simplifies one or more of the line segments that are draped, the simplified line segments and the simplified surface description are rendered onto a display device.

Abstract: A method and system for generating a path to be followed by a cutting tool i n a milling situation. Using a novel geometric concept suited to a milling situation called "focal areas," a toolpath is generated in which the cutting tool remains in constan t contact with material to be cut, thus minimizing wear and shock loading of the tool. In addition, the toolpath is optimized so as to trace a short path, thereby minimizing cuttin g time. The toolpath generator is particularly useful in high speed milling applications .

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.

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 computerized method of drawing provides sketching-type drawing capabilities in a computer-aided design (CAD) environment. Geometrical drawing parts or elements, sketched through a hand-controlled indicator and lacking in the precision criteria or standards associated with formal drawings, are recognized and interpreted as points, straight lines, open arcs, circles and ellipses. Delete and "areafill" symbols, similarly, are recognized and interpreted. The method also provides the capability to distinguish and interpret relatively complex, multiple-part or element strokes. This is done by determining break locations for the elements along the stroke, and by recognizing these elements before re-constituting a stroke meeting precision criteria. A variety of geometrical constraints which are important in a CAD environment, including coincidence, parallelism, tangency and relimitation, are also recognized and imposed. The recognizing of geometrical elements includes the use of pattern recognition and the use of a neural net. The determination of breaks incorporates the calculation of functions representative of changes in angle, of curvature, and of changes in slope, and the classification of information elements representative of locations, based on such calculations.
