Plane Geometry Pattern Embossed Machine Cad Software Development

This paper mainly introduces the project planning and realization method of a kind of CAD application for designing embossment with plane geometry patterns. The main content include introduction to the development environment of AutoCAD R14, introduction to general scheme and introduction to one of prime modules ?fillet module. The emphasis is introduction to the design idea and realization of algorithm of fillet module. This module takes full advantage of the abilities of R14 to handle 2 and 3 dimensions graphics, provides users with visual concise and practical interface and modeling measures. As a instance of secondary exploitation of a existed commercial CAD software, many questions discussed in this paper are representative, such as module partitioning of application, design of user interface, design of dialogue manner, data management and so on.
