Computer-aided design (CAD) tools are widely used in the urban planning process, giving planners the ability to generate urban contexts and many scenarios for future development. However, debate is ongoing regarding the effects of CAD tools on student learning and the reliability of the cluster of assumptions that usually come with them. This article aims to examine whether CityCAD can be an effective tool for achieving learning objectives related to critical thinking, problem-solving, and creativity in the urban planning discipline. This research also examines whether the software influences students’ interest in planning and affects students’ perceptions of the discipline. Using instructor observations, students’ projects, and surveys, we find that using CityCAD in education can achieve learning objectives, increase students’ interest, and enhance the perception of planning as a more creative field. The results have implications for instruction, student recruitment, and perceptions of the field.

Abstract Computer aided design tools are gaining popularity in industry due to their ability to model the geometric aspects of products. This has shown substantial benefit for reducing the need and expense of building physical prototypes and allowing parts and tooling to be manufactured directly from these models. However, the current capabilities in existing CAD tools for modeling assemblies are quite limited. In this paper we introduce a representation for describing interfaces between parts within hierarchical assemblies for capturing functional and physical mating relations. This representation is designed to support automated reasoning and automated generation and modification of assemblies. It is also designed for use with very large assemblies, compactly representing the interfaces of parts and assemblies that are reused within larger assemblies. We describe how this representation is used in our prototype design system, Genesis, for designing aircraft systems.

The Impact

AbstractThis paper presents a preliminary comparison between the role of computer-aided design (CAD) and sketching in engineering through a case study of a senior design project and interviews with industry and academia. The design team consisted of four senior level mechanical engineering students each with less than 1 year of professional experience are observed while completing an industry sponsored mechanical engineering capstone design project across a 17 week semester. Factors investigated include what CAD tools are used, when in the design process they are implemented, the justification for their use from the students' perspectives, the actual knowledge gained from their use, the impact on the final designed artifact, and the contributions of any sketches generated. At each design step, comparisons are made between CAD and sketching. The students implemented CAD tools at the onset of the project, generally failing to realize gains in design efficiency or effectiveness in the early conceptual phases of the design process. As the design became more concrete, the team was able to recognize clear gains in both efficiency and effectiveness through the use of computer assisted design programs. This study is augmented by interviews with novice and experienced industry users and academic instructors to align the trends observed in the case study with industry practice and educational emphasis. A disconnect in the perceived capability of CAD tools was found between novice and experienced user groups. Opinions on the importance of sketching skills differed between novice educators and novice industry professionals, suggesting that there is a change of opinion as to the importance of sketching formed when recent graduates transition from academia to industry. The results suggest that there is a need to emphasize the importance of sketching and a deeper understanding as to the true utility of CAD tools at each stage of the design process.

Computer-aided design (CAD) tools are frequently employed to verify the design objectives before the fabrication of an integrated circuit. An important circuit parameter that requires accurate characterization is the power consumption due to the strict constraints on the acceptable power envelope of integrated systems. Circuit simulators typically provide built-in functions to measure the power consumption. However, the accuracy of the measured power is mostly overlooked since the approximations and the methodologies used by the existing built-in power estimation tools are not well documented. The research community tends to assume that the built-in functions provide accurate power figures. This blind-trust in the CAD tools, however, may lead to gross errors in power estimation. A generic methodology to accurately measure the power and energy consumption with the circuit simulators is described in this paper. An equation to calculate the device power consumption based on the different current conduction paths in a MOSFET is presented. An expression for the total power consumption of a complex circuit is derived by explicitly considering the different circuit terminals including the inputs, the outputs, and the body-contacts. Results indicate that the power measurements with the built-in functions of widely used commercial circuit simulators can introduce significant errors in a 65 nm CMOS technology. For deeply scaled nano-CMOS circuits, a conscious power and energy measurement with the proposed explicit methodology is recommended for an accurate pre-fabrication circuit characterization.

AbstractIn this paper, due to the importance of maintaining a secure grip with the control hand in kayaking, a simple three phase process is presented for the massive development of personalized grips which allow the improvement of this handgrip. This process consists of obtaining the 3D geometry of the paddler's handgrip by using Reverse Engineering (RE) tools, designing the grip from the obtained 3D geometry by using Computer Aided Design (CAD) tools and manufacturing the grip by using Additive Manufacturing (AM) tools. Therefore, this paper shows that the RE, CAD and AM tools available today allow the customization of products for many applications.

This chapter discusses the difficulties of CAD assessment through examining and reviewing existing CAD examination questions in Hong Kong. Based on the review, limitations of the current assessment are highlighted. It is argued that the existing method is inconsistent with the problem solving nature of the software and is unable to assess students with high ability and advanced drawing skills. Recommendation and improvement directions are suggested in the chapter to optimize the quality of assessment. Other subjects which also involve assessment of computer skills and design may also benefit from the recommendations.

This study developed a designer-oriented smart home device computer-aided design tool that can help architectural designers to design smart home. This design tool is intended to incorporate smart home devices into overall spatial planning from the beginning of the planning process. Cloud computing [1] facilitates opportunities for online collaboration and coordination between individuals, between individuals and objects, and between objects, and will help speed the evolution smart home from centrally-controlled intelligent buildings to "smart living space" emphasizing distributed computation ability. This study employs (1) the theory of intelligent agents and (2) scenario-oriented design as an integrated framework for computer-aided design of smart home device. Smart home device are redefined based on agent theory. Agents' behavioral models include the five types of passive, reactive, active, interactive, and communicative; a comparison of these types provides a basis for the selection of home elements. Scenario-oriented design is employed to construct a smart living space (the AI. Living Lab.), which verifies the feasibility of the interface's operations. Finally, the resulting design methods and practical results are used to create a system development blueprint. Real life scenarios provide a basis for communication with smart home industry collaborators, enabling architectural designers to perform scenario modeling of a smart home proposal, quickly and conveniently establish a smart home information modeling system, and promote teamwork with smart home industry personnel.

This paper focuses on a common drawback in electromagnetic numerical computer aided design computer aided design (CAD) tools: high frequency structure simulator (HFSS), computer simulation technology (CST) and FEKO, where the excitation by using a wave-port below and close to the cutoff frequency has unreliable values for the reflection coefficient. An example for such problem is presented in the design of a dual horn antenna fed by two different waveguide sections. To overcome this numerical error in the results of these CAD tools, a tapered waveguide section is used in the simulation as an excitation mechanism to the feeding waveguide. The cross section of the input port at this tapered waveguide section is designed to have a cutoff frequency smaller than the lowest frequency under investigation for the original problem. Then, by extracting the effect of the tapered section from the obtained reflection coefficient, it would be possible to obtain the reflection coefficient of the original problem.
