53、This paper describes the process of developing a virtual 3D modeling platform. The method of thorough study and application of virtual 3D modelingdevelopment platform with Unified Modeling Language standard UML for software engineering design is found, and build a MFC-based interface framework and f

54、inish the interface design process. In this paper, using Open CASCADE 3D geometric modeling kernel, realize an independent modeling, complex Boolean operation of the virtual 3D modeling platform development finally.In this paper, the CAI courseware on Engineering Graphics the status and the developm

55、ent and application of the issues is discussed, the topic of study is expound as well as the background, purpose and significance .On this basis, the technical line and the use of development tools and understanding is introduced. All kinds of methods of Kernel analysis of the geometric characterist

56、ics of the environment and its applications are analyzed.This paper analyzes the UML design to the role of the software design and the use of UML modeling software Italy justice, and then introduced the system in general use UML modeling process. Namely : natural language requirement of the system a

57、nalyzed, the system use case model; Use case model-driven system development process, including design and structural models of window design model class diagram drawn category; Finally, UML modeling to the process of using files in the form of record for reference and research in the future. Becaus

58、e of the lack of specific provisions of UML window view, the window frame design of this system is made. MFC framework of the restructuring of the system window interface framework for the establishment of virtual environment technology. MFC framework of the relevant content analysis, and interface

59、design for the main content, include menu column Graphic tools, noting that the modeling and control area interface and the interface for the design and realization of the related program. Virtual 3D geometric modeling kernel module is platform independent modeling, Virtual model of the various and

60、complex operation of the key. This paper analyzes the Open CASCADE geometric kernel and manifestations, it provides the basic working principle and the OC AF guides tools based on the use of its library design manifestations single file application framework; On this basis, entity type model and a p
