With the rapid development of China's space industry, digitization and intelligent is the tendency of the future. The applications of the waveguide are gradually widespread. During the thermal test phase, the routes of the test waveguides are similar for each spacecraft. Although the waveguides are highly standardized, so far it needs engineers to design the particular route of the test waveguidess, then map the engineering drawing for every test. In order to efficiently design the route of waveguide, it needs to design an application to help the engineers. With the help of the MFC(Microsoft Foundation Classes) and the pro/toolkit, it is easily to do the modeling and simulation. After automatic design the particular the route of the waveguide, the API of AutoCAD type library is used to help to modify the engineer drawing. Engineers can supervise every step of this application, and easily to modify the key parameters.

Due to the rapid development of technology, the use of numerically controlled machines in the industry is increasing. The main idea behind this paper is computer-aided design (CAD) based low-cost computer numerical control 2D drawing robot that can accurately draw complex circuits, diagrams, logos, etc. The system is created using open-source hardware and software, which makes it available at a low cost. The open-source LibreCAD application has been used for computer-aided design. Geometric data of a CAD model is converted to coordinate points using the python-based F-Engrave application. This system uses the Arduino UNO board as a signal generator of the universal g-code sender without compromising the performance. The proposed drawing robot is designed as a low-cost robot for educational purposes and aims to increase the student's interest in robotics and computer-aided design (CAD) skills to the next level. The drawing robot structure has been developed, and it meets the requirements of low cost with satisfactory experimental results.

Today’s customers not only look at aesthetic beauty but also quality, comfort and fit. New technologies such as digitization and virtual 3D tailoring are providing more options to consumers and designers in designing different styles with the least possible time. Next to the shoe fashion and style, good fit and comfort are the second important determinant in the purchase of footwear. Although there is a need for better fitting, there are no techniques for fit quantification. In traditional shoemaking, the shoe is categorized by the length and width (or girth), hence there is always a mismatch between the complex foot shape and shoe shape. For the industry in order to meet the demand for better footwear, new techniques for fit quantification is required in order to have a direct mapping form foot to shoe-last (a mold for making shoes). In recent years, with the rapid development of computer technology and advanced design and manufacturing technologies such as computer-aided design (CAD) and computer-aided manufacturing (CAM), the manufacturing of customized shoe lasts is becoming possible. Still research is needed to find the best shoe-last. This paper discusses the basic concepts and current methods being followed to convert foot to shoe-last, retrieve the best fitting shoe last based on the 3D foot scan of the customer, and to obtain customized shoe last.

With the growth of information technologies in the field of computer-aided design, the concept of CAD acquires new meaning and changes the contents. More and more a new definitions, i.e. Building Information Modeling - BIM, Fabrication Information Modeling - FIM, Integrated Structural Modeling - ISM, Building Lifecycle Management - PLM and others are encountered, the concept of which may be described as way to develop the strategy of building project design, construction, and maintenance management based on the computer aided modeling and simulation technologies. Examine BIM application in building design process it can be assumed that of object modeling and simulation technique comprises a full range of actions starting from the development of virtual model of the project under consideration, describing all physical parameters characteristic of a real structure, defining the conditions of its position. Then analysis of model behavior under real maintenance conditions is performed: effects of different character are described and the results obtained are analyzed. The results received by next step are presented in common technical documentation form: general arrangement and erection drawings are generated, final detailing of connections and structural elements in the form of shop drawing or NC code is performed, bill of materials, cut lists, various reports, specifications and estimates are composed. During the last five years there is strong request from the market for the state-of-the-art computer-aided design applications developed to meet the needs and requirements of the Architectural, Engineering, and Construction as well as Plant, Process, and Power industries, for high performance, flexible and versatile tools with extended graphics integration to simulation and analysis systems within a user-friendly design environment that allows the close emulation of natural design phases and workflow to which structural are accustomed. This could became possible due to the innovative development of ‘new generation’ structural software application capable to maintain an intelligent and true 3D real-world simulated structure containing all the information required for the general and detailed design, fabrication and construction of engineering structures, enabling designers to operate intuitively in the adaptive high-performance real-time visual modeling environment while simultaneously achieving high-quality results by applying powerful simulation, analysis and optimization methods which would guarantee a rational and effective choice of the constructive decision. It has to be flexible to enable external best of breed vertical market products to be linked to the application and hence creating an open design environment; this enables members of a workgroup to collaborate effectively, performing the multiple tasks associated with construction design.
