【摘要】 厨房家具既是满足现代厨房炊事功能的用具，又是美化厨房环境的要素。它需要和建筑紧密结合，进行现场设计，将厨房中的电、水、燃气和使用这些能源的各种家用电器、燃气用具等有机地结合在一起，使人们的饮食烹调活动变得更加方便，更具科学性，同时兼有住宅室内的装饰性。随着人们生活水平的不断提高，生活方式也在不断变化，这就要求家具设计也要根据用户的需求动态地做出相应的变化。因此，如何运用高科技手段进行计算机辅助设计，设计出更加符合用户需求的家具产品，从而使家具行业取得进步，求得发展，是个值得我们深入研究和探讨的问题。 论文主要介绍如何运用ObjectARX对RTA厨房家具CAD系统(简称KFCAD)进行研究与开发，首次综合运用面向对象的设计思想、对象的抽象机理以及ObjectARX编程技术建立家具CAD的对象模型。同时，利用特征建模的方法和参数化设计方法对家具三维计算机模型的建立进行了比较深入的研究。 KFCAD采用模块化设计的方法自顶向下开发。采用Visual C++开发ObjectARX应用程序，在运行效率、对象管理、用户界面、智能化程度等方面都取得了新的进展；利用AutoCAD核心数据库的开放结构和ObjectARX提供的基类及类的继承、派生机制来定义专业对象类，体现了面向对象技术的实质；利用特征建模的技术，实现了参数化绘图功能；采用标准的Windows应用软件风格，友好的对话框设计界面，使用户操作简单容易；实现了符合家具设计和生产用的零件图、结构装配图、下料图、工艺分析及各种材料统计表等的快速生成。 系统不同于以前的AutoLISP和ADS都是面向过程的设计方法，而采用了ObjectAPX面向对象程序设计的方法，研究和开发出了更适合厨房家具的计算机辅助设计系统，具有一定的实用性和创新性。同时，系统的建成对于家具设计人员、生产厂家和大中专院校有关专业师生都有很大的参考和使用价值。更多还原

【Abstract】 Kitchen furniture is the appliance for contenting the function of modern kitchen cooking, and the factor for beautifying the kitchen environment as well. It integrates closely the architecture and requires the designing of the scenes, with integrated electricity, water, natural gas and the sources of energy utilized by varied home appliances, gas appliances and etc. At the same time, it makes people activities biting and cooking become much more convenience, take on science character and have the decoration to the residence interior. With the people living level enhancing and the mode of life changing, these require the furniture designing to display dynamic variety according to the consumer demand. Consequently, it is deserved to investigate and discuss the problem that how to bring to bear the means of science and technology to carry through Computer Aided Design and how to design the furniture much more demanding consumer which make the furniture trade acquire the advancement and seek the development.The thesis mainly study and develop how to apply ObjectARX to RTA kitchen furniture CAD (Abbreviation: KFCAD). At the same time, it erects the object model of furniture CAD to bring together by the object-oriented design idea, the mechanism of object abstract and the program technology on ObjectARX, and also deeply researches furniture 3D model by the modeling method based on character and the design method of parameter.KFCAD system used the principle of modularization design and the thought of structural design. The main system, selecting the newly object-oriented visual software Visual C++ 6.0 as the development tool, has the new evolvement on running efficiently, object managed, friendly view, intelligent degree and etc. Moreover, it embodies the essential of object-oriented technique by the open structure of AutoCAD core database and ObjectARX base class, class inheritance and mechanism derived to define the special object-class. And the system realized the parametric design function to make use of the modeling method based on character, has the traits of convenient operation to adopt the style of standard Windows software and friendly dialog box view. The system comes true accessory drawing, configuration assembled drawing, production technics flowing table and varied material statistics and etc which accord with furniture designed and produced to build quickly.The system used the method of ObejctARX object-oriented program design, which differs from process-oriented design for example AutoLISP and ADS before, to research and develop CAD system that much more fit kitchen furniture and have specific practicability and innovation. At the same time, the accomplishment of the system has a great many reference and employ worthiness for furniture designer, manufacture, correlation special teacher and student.更多还原
