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.

然后循環(huán)從特征庫中選擇所需要的特征，通過特征參數(shù)表和定位參數(shù)表給出特征參數(shù)和定位參數(shù)，并進(jìn)行特征裝配，建立形狀特征模型。之后輸入其它特征信息，建立產(chǎn)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軟件只能實現(xiàn)平面的輪廓圖，但目前SolidWorks軟件使用的比較多，因為它能實現(xiàn)立體效果，這樣根據(jù)用戶就能在電腦上看到自已想要的不銹鋼機箱機柜立體效果圖，即方便又快速的呈現(xiàn)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

利用這種思想建立的特征零件模型具有以下特點：

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

（1）集成性特征造型系統(tǒng)為下游應(yīng)用的各環(huán)節(jié)提供了一個具有幾何、屬性和知識的信息完備的產(chǎn)品模型，從而為CAD、CAPP和CAM各應(yīng)用模塊的集成提供了實現(xiàn)的基礎(chǔ)。

(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）表達(dá)信息的豐富性相對于幾何造型軟件，基于特征建模提供了一種更自然方便表達(dá)設(shè)計者意圖的方法，允許設(shè)計者直接用工程術(shù)語描述零件。

(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）信息描述的多層次性產(chǎn)品模型既有高層次的特征參數(shù)和特征關(guān)系，又有低層次的幾何拓?fù)湓兀环矫鏋楹罄m(xù)的特征評價提供了高層次的語義信息，另一方面為尺寸和精度特征的表示提供了依據(jù)實體。

(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.
