As most existing computer‐aided design systems do not provide part feature information which is essential for process planning, automatic part feature recognition systems serve as an important link between Computer Aided Design (CAD) and Computer Aided Process Planning (CAPP). Attempts to provide a structural framework for understanding various issues related to part feature recognition. Reviews previous work in the field of part feature recognition and classifies known feature recognition systems for the sake of updating information and future research. Briefly introduces about 12 systems. Studies 31 systems and lists them in the Appendix based on 60 references. Comments on future research directions.

Despite the benefits of computer‐aided design (CAD), its uptake by the garment industry in the UK has been somewhat slow. Many reasons have been suggested for this, one of which is the lack of appropriately skilled designers and pattern cutters. Comments on this situation and describes a garment CAD‐training programme set up at De Montfort University, Leicester. This training programme was used as the basis of an attitude assessment. A questionnaire‐based survey was developed to quantify the designers’ opinions of CAD and specifically whether these opinions were influenced by the designer’s age or prior computing experience.

Training is one of the key elements to the success of computer‐aided design (CAD). In the past, CAD educators concentrated their efforts in design engineers and draftsmen. The trend in the manufacturing environment towards integration of computerised systems is discussed. This trend has created a great demand for CAD training tailored to the needs of users of systems that are linked to CAD.

In order to present a significant usage of the computer-aided design (CAD)/computer-aided manufacturing (CAM) systems in the apparel and textile industry, the current literature has been observed. Although the CAD/CAM systems have also been increasingly applied to all fields apparel and textile manufacturing for the last few decades, improving the precision, productivity and the organization of the information flow, they have not been fully utilized in these industrial fields. The paper aims to discuss these issues.

The paper is structured in three main sections showing the vast applicability of the CAD/CAM systems, the benefits provided by them and the future trend in their development.

Although the initial development of the CAD/CAM systems strived to completely eliminate manual and time-consuming operations, they have not been accepted in practice due to their inflexibility at making changes and the time needed for regenerating a complex parametric model. The textile and apparel industries show slow progress in acquiring the CAD/CAM systems.

This CAD/CAM technology enabled the customization in the design process according to individual needs and directed the textile and the apparel industry to moving into new directions such as the mass customization to personalization. The paper makes clear that although this technological concept is rather old, the use of the CAD/CAM systems will inevitably broaden in terms of applicability to new production stages.

‘Computer aided design’ and ‘Computer aided drafting’ have become part of the jargon of the construction industry of the 1980s. However, building surveyors have been slow to adopt CAD. To a great extent this has been because of two misconceptions: that CAD is inapplicable to existing buildings because they lack repetition. that CAD is inapplicable to buildings because they are not square. Contrary to this widely held view, computer aided drafting can be effective and economically viable for refurbishment and rehabilitation projects. Drawings from refurbishment projects prepared using CAD will be used in this paper to demonstrate some of the advantages of CAD, and to identify those areas of the drawing production process where CAD can lead to increased productivity and other worthwhile benefits.

The purpose of this paper is to report a research which is conducted to examine the power of computer aided design (CAD) in achieving agility in traditional organizations.

The CAD model of the knob of an electronic switch was developed. This model was shown to the team of executives. The theoretical and practical knowledge provided by them were utilized to design new ten CAD models of the knob. The reactions of the executives about these new models were gathered and analyzed.

The creation of a CAD model of an existing product is found to be a useful input for evolving new models in an agile manner. It is found to be an easy task to gather the theoretical and practical knowledge for achieving design agility through the visualisation of CAD models.

This paper is conducted on only one component manufactured by an electronic switches manufacturing organization. Although it appears to be a limitation of this paper, the nature of the design process carried out in this traditional organization mimics that of any other design practices carried out in the world. Hence, the contributions of this paper are applicable in traditional manufacturing environment.

Throughout the conduct of this research, the practitioners' views are gathered. Their views are favorable towards the successful usage of CAD model in achieving design agility.

For many years, CAD has been used for carrying out complex design projects. However, it appears that it has not been used in its simplest form to visualise and bring out new models electronically for achieving design agility. This simple approach is presented in this paper which may be used by both theorists and practitioners.

This paper aims to present a reverse engineering (RE) approach for three-dimensional (3D) model reconstruction and fast prototyping (FP) of broken chess pieces.

A case study involving a broken chess piece was selected to demonstrate the effectiveness of the proposed unconventional RE approach. Initially, a laser 3D scanner was used to acquire a (non-uniform rational B-spline) surface model of the object, which was then processed to develop a parametric computer aided design (CAD) model combined with geometric design and tolerancing (GD&T) technique for evaluation and then for FP of the part using a computer numerical controlled (CNC) machine.

The effectiveness of the proposed approach for reconstruction and FP of rotational parts was ascertained through a sample part. The study demonstrates non-contact data acquisition technologies such as 3D laser scanners together with RE systems can support to capture the entire part geometry that was broken/worn and developed quickly through the application of computer aided manufacturing principles and a CNC machine. The results indicate that design communication, customer involvement and FP can be efficiently accomplished by means of an integrated RE workflow combined with rapid product development tools and techniques.

This research established a RE approach for the acquisition of broken/worn part data and the development of parametric CAD models. Then, the developed 3D CAD model was inspected for accuracy by means of the GD&T approach and rapidly developed using a CNC machine. Further, the proposed RE led FP approach can provide solutions to similar industrial situations wherein agility in the product design and development process is necessary to produce physical samples and functional replacement parts for aging systems in a short turnaround time.
