When we design the effect drawing of stainless steel cabinet, some old batch of stainless steel cabinet designers like to use AutoCAD as the feature modeling to establish the design platform of stainless steel cabinet sheet metal part product model, and introduce parametric technology. The designer establishes a feature library in advance, which contains the features of sheet metal parts of common stainless steel chassis and cabinets, such as flat plates, holes and various forms of grooves. The design is to first input the overall information of the parts, select the matrix features in the feature library, generate the matrix features, and carry out feature assembly modeling on this basis.

然后循环从特征库中选择所需要的特征，通过特征参数表和定位参数表给出特征参数和定位参数，并进行特征装配，建立形状特征模型。之后输入其它特征信息，建立产品特征模型。

Then, the required features are selected from the feature library, the feature parameters and location parameters are given through the feature parameter table and location parameter table, and the feature assembly is carried out to establish the shape feature model. Then input other feature information to establish the product feature model.

AutoCAD软件只能实现平面的轮廓图，但目前SolidWorks软件使用的比较多，因为它能实现立体效果，这样根据用户就能在电脑上看到自已想要的不锈钢机箱机柜立体效果图，即方便又快速的呈现在眼前。

AutoCAD software can only realize the plane outline drawing, but at present, SolidWorks software is used more, because it can realize the three-dimensional effect, so that users can see the three-dimensional effect drawing of stainless steel cabinet on the computer, which is convenient and fast in front of their eyes.

Conclusion of stainless steel cabinet

利用这种思想建立的特征零件模型具有以下特点：

The feature part model established by using this idea has the following characteristics:

（1）集成性特征造型系统为下游应用的各环节提供了一个具有几何、属性和知识的信息完备的产品模型，从而为CAD、CAPP和CAM各应用模块的集成提供了实现的基础。

(1) The integrated feature modeling system provides a product model with complete information of geometry, attributes and knowledge for each link of downstream application, which provides the basis for the integration of CAD, CAPP and CAM application modules.

（2）表达信息的丰富性相对于几何造型软件，基于特征建模提供了一种更自然方便表达设计者意图的方法，允许设计者直接用工程术语描述零件。

(2) Compared with geometric modeling software, feature-based modeling provides a more natural and convenient method to express the designer's intention, which allows the designer to describe parts directly in engineering terms.

（3）信息描述的多层次性产品模型既有高层次的特征参数和特征关系，又有低层次的几何拓扑元素，一方面为后续的特征评价提供了高层次的语义信息，另一方面为尺寸和精度特征的表示提供了依据实体。

(3) The multi-level product model of information description not only has high-level feature parameters and feature relations, but also has low-level geometric topology elements. On the one hand, it provides high-level semantic information for subsequent feature evaluation, on the other hand, it provides entity basis for the representation of size and precision features.
