1.1 Summary of 3D design software
CAD software category from the 20th century to the 1960s computer-aided geometric design was mainly to resolve the graphics on the computer display and describe the problem, then gradually raised wireframe, surface, geometric entities such as physical description model. Today, a total experienced the following stage.
 computer graphics stages: focused on solving computer graphics, surface expression, and other basic issues.
 technical parameters and characteristics of the stage: resolving CAD data control and modification.
 intelligent design stages: in the design of integrating more engineering knowledge and rules, to achieve a higher level of the computer-aided design.
After 40 years of development, 3D design software has been developed from a simple drawings or product model generation tools, development can provide a wide range of engineering support, covering design intent expression of design standardization, serialization, and design results of the analysis can be created, interfere with the inspection process of judgement, design optimization, and many other aspects. 3D design the model can be converted to support CAE (computer-aided engineering) and CAM (computer-aided manufacturing) applications data format. 3D design these features meet the needs of the project, which have greatly increased the quality of product development and efficiency, greatly reducing the product design and development cycle.
At present, large-scale manufacturing enterprises at home and abroad, the 3-D design software has been widely used. American companies such as Boeing use 3D design and related software, in the two and a half years, achieving the 777 non-design drawings. According to the traditional design work, the whole process requires at least four years. The company also works in the implementation of the widely used parallel engineering technology, in the CAD environment with the overall product virtual assembly, the number of correct design errors, thus ensuring that the design process of the short cycle, the outcome of the high-quality design and manufacturing process the fluency.
The extensive use of three-dimensional design software can be divided into high-end and mid-range CAD systems, the high-end 3D CAD software mainly I-DEAS, UG, Pro / ENgineeR, CATIA, mid-range 3D CAD system mainly SolidWorks, SolidEdges, MDT, Inventor, etc.. The general manufacturing enterprises, and the powerful features of SolidWorks to complete the general design task, and it is its ease of use and efficiency has also aroused the concern of more and more users.
3D design software experience from simple geometric model generation tools to technology to variable control of the product model, ultimately forming a complete enterprise digital process. 3D design software applications greatly enhance the efficiency of product design and development.
Compared to 2D design (CAD), the biggest feature of the 3D design feature is the use of modeling techniques and the entire design process related technologies. 3D design software is not only a powerful modeling functions, but also provides a wide range of engineering support. Including a description of the design intent, design and design reuse, such as serialization.
3D design into part design, assembly design and engineering drawings generated three stages. Related to the entire design process, makes any stage revised design will affect the other results of the design stage, thus maintaining the model in a variety of consistency in the design environment, thus improving design efficiency.
1.1.1 Part Design
Parts design is the basis of three-dimensional design. Parts are generally in the form of three-dimensional entities, as shown in Figure 1.1 for loading vehicles in the "bucket" model of spare parts. Parts entities from the point of view of modeling, parametric feature-based modeling and 3-D design has become a mainstream technology. In different parts of the processing entity known as the characteristics of different combinations of features on the formation of a three-dimensional solid model parts. Not only has the characteristics of the corresponding projects, but also through the topological relations between the characteristics and timing relations can be flexible control of modeling results.
Parts of the three-dimensional solid model, in the design and manufacturing process to achieve the following features.
 generate engineering drawings parts.
 parts of the stress analysis and strength check.
 formed assembly, test the reasonableness of the design.
 formation of mold parts.
 generated NC code, direct machining.

1.1.2 assembly design
3D design software assembly is the basic function of one. Figure 1.2 shows the toys "loader" assembly model. In modern design, can make use of the existing three-dimensional model parts will be two or more parts in accordance with certain constraints relationship assembly, formation of virtual product assembly; also can be used to project more in line with the top-down assembly design approach , in the assembly environment, in reference to other parts of the assembly of the location and size of the design of the new parts and assembly. At the same time, the assembly has been expanded to more engineering fields, such as motion analysis, interference checking, etc.. 3D design software product assembly environment has become the basis for comprehensive performance verification environment.
The use of virtual product assembly model, the following functions can be realized.
 a product of the true effect maps, verify that the product structure, analysis and design.
 products generated view of the explosion.
 the product movement analysis and dynamic simulation depicts moving parts specific point trajectory.

1.1.3 Engineering Graphics Generation
Use of parts and assembly solid model can be automatically generated assembly of parts and 2D engineering drawings. And compared to traditional CAD, 3D design software engineering drawings generated much simpler to operate, only specified model projection direction, insert size, and then details can be set up engineering drawings. Figure 1.3 shows the SolidWorks automatically generated as shown in Figure 1.1 and the "bucket" parts of the corresponding engineering drawings.
