Abstract The several loops characterizing the design process used to slow down the development of new projects. Since the 70s, the design process has changed due to the new technologies and tools related to Computer-Aided Design software and Virtual Reality applications that make almost the whole process digital. However, the concept phase of the design process is still based on traditional approaches, while digital tools are poor exploited. In this phase, designers need tools that allow them to rapidly save and freeze their ideas, such as sketching on paper, which is not integrated in the digital-based process. The paper presents a new gestural interface to give designers more support by introducing an effective device for 3D modelling to improve and speed up the conceptual design process. We designed a set of gestures to allow people from different background to 3D model their ideas in a natural way. A testing session with 17 participants allowed us to verify if the proposed interaction was intuitive or not. At the end of the tests, all participants succeeded in the 3D modelling of a simple shape (a column) by only using air gestures in a relatively short amount of time exactly how they expected it to be built, confirming the proposed interaction.

In this article is presented a short classification for walking robots that are based on leg locomotion and the main objectives that walking robots designers must achieve. The leg configuration of the walking robot is essential for obtaining a stable motion. Computer aided design process offers certain advantages for designers who attend to realize competitive products with fewer errors and in a short term. The aim of this article is to present the graphical results of the kinematic analysis of a new type of walking mechanism designed by Dutch physicist and sculptor Theo Jansen using Pro Engineer program and SAM, in order to compare the results.

In the office, computers are central to a range of tasks. The architects’ days are mostly spent at screens: checking and responding to e-mail, finding “precedent” images that provide the inspiration for design, researching building materials and new technologies, and most centrally of all using one of a range of computer-aided design packages. Watching them at work, I observe screens flicking perpetually between these programs and tasks. Observing their movements, I find it clear that these architects are thoroughly digital humans, their capacities of thought and action indissoluble from digital technologies that saturate this working environment....

This chapter focuses on the development and adoption of new Multimedia, Computer Aided Design, and other ICT technologies for both Architecture and Computer Science curricula and highlights the multidisciplinary work that can be accomplished when these two areas work together. The authors describe in detail the addressed educational skills and the related developed research and highlight the contributions towards the improvements of teaching and learning in those areas. This chapter discusses the role of digital technologies, such as Virtual Reality, Augmented Reality, Multimedia, 3D Modelling software systems, Design Processes and its evaluation tools, such as Shape Grammar and Space Syntax, within the Architecture curricula.

In modern industrial production some of the major factors of successful development include: cost reduction of the production, im-provement of its quality, as well as help to minimise the time in market en-try. Computer-aided design and Computer-aided engineering (CAD / CAE - systems) are the most effective for implementation of these requirements. Possible use of this engineering modeling simulation in conjunction with the power and speed of high performance computing could reduce costs and time of each cycle of designing, and also significantly reduce devel-opment time. The introduction of new technologies, the use of high quality products and engagement of qualified personnel would allow businesses and organizations to get on a path of innovative development of design and production systems.

Flexure mechanisms are the central part of numerous precision instruments and devices that are used in a wide range of science and engineering applications and currently, design of flexure mechanisms often heavily relies on designers’ previous hands-on experience. Therefore, a design tool that will speed up the design process is needed and this paper will introduce a systematic approach for building the necessary equations that are based on screw theory and linear elastic theory to analyze flexure mechanisms. A digital library of commonly used flexure elements must be available for a design tool and therefore, we first present the compliance matrices of commonly used flexure components. Motion twists and force wrenches of the screw theory can be related with these compliance matrices. Then, we introduce an algorithm that constructs the required linear system equations from individual compliance equations. This algorithm is applicable to flexure mechanisms with serial, parallel or hybrid chains. Finally, the algorithm is tested with a flexure mechanisms and it is shown that this approach can be the core of a future design tool.

Control moment gyroscope or two-axis balking gyroscope is used in spacecraft orientation systems. The control moment gyroscope is a complex electromechanical system with different parameters which connect by means of specific instant and inverse dependences. This fact could complicate the design process as of getting the optimal parameters the search of construction variations becomes harder. To simplify the control moment gyroscope designing process and increase its efficiency the computer-aided design system could be as highly useful. The computer-aided design system which is used in the present research and described in the article consists of five main subsystems. They cover the main stages of control moment gyroscope designing.

In order to provide products that can be tailored to the need of the customer, it is necessary to integrate the customer into the design process. In this paper we present a mass customization computer-aided design (CAD) framework that helps to integrate the customer into the design of user-configurable products. A template approach, which considers both modularity and scaling, is utilized to concisely represent a CAD model of the entire family. The system accepts user selections and parameters to automatically create a CAD model of the customized product in real time and then shows the model to the user. The system is implemented using PRO/ENGINEER and demonstrated through customization of bicycle frames.

The Computer Aided Design and Computer Aided Manufacturing are the modern innovative technology in garments manufacturing like all other manufacturing sectors. Garments CAD is specially used for pattern designing and marker making. On the other hand CAM is used for fabric cutting and other manufacturing sections. Before implementing those new technologies, manual system was widely used in garments sector. In recent time some large garments factories of Bangladesh are starting to adopt CAD and CAM technology. Beside that a huge number of medium and small size factories are using manual system yet. This paper presents a feasibility study of CAD and CAM technology in above mentioned different size factories in Bangladesh. The Study is carried out in respect of production procedure, required man power, production/hr, product quality, production efficiency, and production cost. The practical investigation and data shows the scenario that all types of garments industries are not capable to use CAD & CAM and also not even profitable for them.
