Abstract


With the development and application of CAD / CAM technology reaches a certain level , requiring further enhance the integration of the production organization , degree of automation . We know that design is an iterative optimization for the solution process , the system should be adapted to dynamically modify the course of their work . The actual design work is often derived design , in particular , hope that the system with variable parameters , traditional geometric modeling method is not conducive to creative design , can not easily modify the design model . Therefore , must be developed to replace the existing solid modeling support system , to provide a comprehensive and multi-level product information for the CAD / CAM system . This information without human intervention in the design, analysis , manufacturing, accepted , and can automatically transform between each application subsystem , CAD / CAM integration, which came into being feature technology . Use of feature-based modeling technology features to define CONTAINED geometry the upcoming feature library of predefined characteristics instance , an instance characteristics as the basic unit to create a feature model , thus completing the definition of manufacturing or design , enabling each CAD application system can be directly extracted from the manufacture of objects in the model of the required information. Feature design can achieve an accurate description of the manufacturing biometric , simplify manufacturing the geometrical specification and capture design ideas of the designer . Therefore, the feature-oriented design technology is the latest and most promising technology of CAD / CAPP / CAM integration . This paper focuses on the definition of planing hull boat type characteristics , based on AutoCAD software platform , VBA development tools to develop a suitable for speedboats type line design software to achieve the rapid generation of solid modeling , the main contents include : 1, elaborated research background, purpose and significance of the ship Feature Design Law statements. 2, describes the characteristics of the speedboat line the speedboat and characteristic parameters are described . 3 , studied mathematics profile design methodology, the main application of mathematical methods in the build process , a more detailed exposition the longitudinal function method frequently used in boat design . 4 , detailing the realization of the principle of the development of language AutoLISP , VBA and AutoCAD secondary development . 5, the structure and function of the software system .
