CAD is one of the current hottest design topics, how to reform the traditional design method of the construction of modern design institute, how to gain economic benefit from the science and technology progress is worth to talk about. CAD technology, as one of the important of the electronic information technology, is to promote the development of the scientific research achievements and transformation, promote the traditional industry and the renewal of the subject.

Speed up the development of national economy and the national defense modernization a key high technology, is also further to computer integrated manufacturing (CIM) development of important technical basis. So, it is necessary to research the main development trends of CAD technology. The improvement and development of CAD technology, mainly in the following respects:

Firstly, modeling techniques. Shaped by the wireframe model, physical model and the non-uniform rational B-spline algorithm is characterized by several parameters of the model has been developed to, and characterization of the variable, the variable-oriented and feature modeling, and future-oriented product life cycle, to achieve the internal description of the product life cycle information (product design, planning, manufacturing, processing, assembly, testing and other information) and external process integration products for the special piece of modeling techniques.

Secondly, Software component technology. It Can improve software stability and development efficiency. Solidworks and Solidege al use Parasolid geometric modeling device, MDT and Microsolid using ACIS geometric modeling, etc..

Thirdly, Windows technology and Internet technology. many companies, such as Autodesk ‘s software technology research and development center of gravity is focus on the prosperous development of the three major technology areas: object technology, 3 d technology and Internet technology, the core technology leads the industry trends of global design.

Fianlly, Intelligent CAD technology, intelligent technology in CAD system will occupies an important position, with the help of expert system intelligence engineering technology, with experts in the field of design experience, to accumulate and renewal, forms the enterprise product design knowledge base, is the precious resources of an enterprise to develop the products.

CAD is a powerful software, its formats such as dwg and dxf are widely used today. But there are also some shortcomings of them, for instance, if you want to share your dwg or dxf files with your classmates, it is not very easy. thus, it is necessary for us to convert dw or dxf to pdf files.
