Designer modeling for personalized game content creation tools

With the growing use of automated content creation and computer-aided design tools in game development, there is potential for enhancing the design process through personalized interactions between the software and the game developer. This paper proposes designer modeling for capturing the designer’s preferences, goals and processes from their interaction with a computer- aided design tool, and suggests methods and domains within game development where such a model can be applied. We describe how designer modeling could be integrated with current work on automated and mixed- initiative content creation, and envision future directions which focus on personalizing the processes to a designer’s particular wishes.peer-reviewe

The Importance of CAD/CAE systems in development of Product Design and Process of Optimization

Computer Aided Design (CAD) and Computer Aided Engineering (CAE) are the most important technology tools that today designers are using in development of product (design and in process of optimization). Thus, this study is carried out to present the importance of CAD/CAE system on process of design and process of optimization of spur gear. The paper presents the usage of CAD system for modeling parts and CAE software for analysis of stress-strain of spur gear and the results of calculation of pair spur-gears that it used in the gearbox transmission of the bucket wheel excavator located in “Bardhi i Madh - Fushë Kosovë”, and after that will be optimized the shape of the spur gear with usage of ANSYS software. Consequently, the aim of this research is to calculate stress-strain structure of parts (gears) and reduce weigh of the gears

Development of a Design for Manufacturing Tool for Automated Fiber Placement Structures

Existing design processes for laminates constructed with automated fiber placement lack significant integration between the various software tools that compose the process. Tools for finite element analysis, computer aided drafting, stress analysis, tool path simulation, and manufacturing defect prediction are all critical parts of the design process. With traditional hand-layup laminates, the analysis performed with each of these tools could be fairly well decoupled from one another. However, for laminates generated by automated fiber placement, the disciplines can become significantly coupled, especially on structures with curvature. This gives rise to a need for integrated design for manufacturing software tools that are able to balance the competing objectives from each discipline. This paper describes the preliminary development of such a tool

Computer Aided Drawing software delivered through Emotional Learning. The use of Emoticons and GIFs as a Tool for Increasing Student Engagement.

It is known that one of the key factors for many manufacturing companies, who are involved in the design and development process, is represented by the quality of the skills, capacity and experience of computer-aided design draftsman and designers. This means that effective, up-to-date and engaging training has to be performed by teachers and instructors, since the early stage lectures for novice engineering students. When learners are engaged and actively participate in the training process, then this transfers in to a high, deep level of learning, quality of the learnt topics and perceived passion. The following question arises, “how can the process of improving the absorption of information concerning Computer Aided Drawing software lectures, through an iterative, engaging process, be facilitated?”. This work represents a fist attempt to analyse and discuss, by using some of the main theories related to the learning process, how student engagement can be positively affected by using emoticons and GIFs during CAD software lectures

A multidisciplinary and collaborative problem solving architecture for high-level computer aided process planning in discrete manufacturing

Student Number : 0111474R - PhD thesis - School of Mechanical, Industrial and Aeronautical Engineering - Faculty of Engineering and the Built EnvironmentOne of the most daunting challenges in Computer Integrated Manufacturing (CIM) is bridging the gap between Computer Aided Design (CAD) and Computer Aided Process Planning (CAPP). Past research into CAPP, considered one of the most important and most complicated computer aided systems, resulted in a wealth of knowledge but unresolved problems still exist. The actual CAPP systems are considered large, complex, and monolithic, with limited extensibility, low-level of integration with other applications, and high development and maintenance costs. Consequently, this thesis develops a new framework that focuses on a CAPP architecture for problem solving that manages complexity through simplicity, and applies principles and strategies used in manufacturing enterprise management, automation, robotics, and software engineering, that finally leads to a system of systems which is human-centric, architectural-centric, process-centric, and in line with the IT (Information Technology) infrastructure trends. Thereafter, the framework is used to develop a number of software applications that apply object-oriented programming as a new way of thinking about solving CAPP problems and as a promising alternative to other techniques. Then, the capabilities of the new approach are demonstrated through the use of examples. The thesis ends with conclusions about the new CAPP approach, and finally highlights its theoretical and practical implications

Designing a 3D Printed Prosthetic to Meet Task-Specific Needs: A Case Study

The purpose of this case study is to explore the ease of utilizing task-specific design in computer-aided, open-source 3D printed design software. Two participants were recruited and assessed using subjective and objective measures to guide the prosthetic designs. Hand measurements were obtained and entered into computer software to create computer-aided design drawings of the digit prosthetics. Field notes were taken throughout this process by the interdisciplinary team and analyzed to address the ease of utilizing this technology. Objective assessments showed that both participants experienced decreased expansion, grip, and prehension strength of their affected hands. Semi-structured interviews with the participants identified several meaningful tasks that a prosthetic device could improve function in and offered valuable guidance in the development of the prosthetic designs. Analysis of the field notes allowed for the identification of six domains within the research questions. Those domains include appropriate assessment utilization, time management, participant responsiveness, clinical reasoning, common language, and available resources. The successful collaboration of occupational therapy (OT) and engineering disciplines resulted in customized 3D printed finger prosthetic designs to meet participants\u27 specified tasks

Using computer graphics and computer aided design methods into the conception of the bolted connections

As a result of the application of the tools provided by the digital computer and interactive computer graphics, the reality of modern mechanical engineering design in the current industrial environment is changing. At the same time, customer expectations for the quality and durability of products are continuously increasing and the constraints of cost and lead-time are becoming more and more compelling. This situation poses new challenges in the product-development process and introducing, also, new demands in the preparing process of tomorrow's engineers and scientists, in order to a proper integration in the engineering curricula of the computer aided design, which eliminates the need for costly changes, unnecessary delays or unsatisfactory design releases. Along these lines, the objective of the paper is to present some of our experimented ways of integrating the CAD basics concepts with the use of a specifically design and analysis software. These techniques, very efficient in the instruction/education period of the futures engineers in mechanical domain, are exemplified with a design software dedicated for bolted joints, which have to transmit static, dynamic and thermal working loads
