“…These inadequacies, along with the limitations of the computer processor with respect to Division's collision detection algorithm, made the exact positioning of any component almost impossible. Therefore, to assist the planner in placing objects in the correct position relative to their neighbours, two joining tools were developed called collision snapping and proximity snapping [46][47][48][49]. The idea of snapping is analogous to that used in traditional CAD systems where a user can, say, pick an intersection or line end-point by positioning the cursor approximately; the algorithm then looks for the nearest point and snaps workers from a collaborating company constructed three assemblies in both the real and virtual worlds.…”

The preparation of assembly plans for manufactured goods is a major bottleneck in the time it takes to bring many new products to market. Computer aided assembly planning (CAAP) systems have been the subject of considerable research in recent years without achieving significant up-take in manufacturing industry. This paper proposes an alternative approach based on the adoption of immersive virtual reality, which is used here to produce practical downstream manufacturing information. The product is assembled from computer aided design (CAD) models of its components by experienced assembly operators working in a virtual environment. The operators' actions are monitored and assembly sequence plans are automatically generated by the system. In the research described in this paper, the plans produced for an advanced electromechanical product were then used by a second group of participants to demonstrate the functionality of the system in an industrial environment. The development of virtual reality-based assembly planning carries with it the opportunity not only to shorten the product innovation cycle but also to capitalize on the experience of assembly operators and bring this to bear much earlier in the design process.

“…Although the development of an integrated approach for cable harness design has been advocated previously [5], there appears to be almost no work bringing together key processes, namely circuit design, harness routing and electrical simulation. Work undertaken at Heriot-Watt University [25,26] aims to research the eectiveness of using immersive VR as the environment where cable harnesses are developed by using the expertise of the cable harness designer rather than by replacing this individual via an automated system. The philosophy is similar to that adopted successfully in parallel work concerned with planning for mechanical assembly [27].…”

Bundles of cables known as harnesses are an essential and costly but often overlooked feature of electromechanical systems. This paper describes the problems and diculties associated with cable harness design and planning and reviews published material on the subject. A case study approach involving a number of advanced manufacturing organizations was used to con®rm current industrial practice. Cable harness design and planning is revealed to comprise a sequential, iterative set of lengthy activities carried out late in the overall product development cycle. It was found that there has been little attempt to integrate any of the core activities involved. The paper concludes with a proposal for a new concurrent engineering approach to cable harness design that makes use of an immersive virtual environment within which stages in the process can be addressed.

“…In the recent years, under the supporting of IT technology and virtual reality technology, the importance of the application of virtual assembly technology in bringing about additional benefits in terms of quality, reliability and shorter manufacturing time is gradually recognized [2][3][4][5]. As one of the key techniques in virtual assembly technology, exploded view plays an important role in the analysis of the product's assembling ability, a well-designed exploded view not only exposes internal parts of complex products, they also illustrate the detail of individual part, furthermore, exploded view can be used to make product catalogue and installation guide by the unique advantage in showing the relationship or order of the assembly of various parts [6][7][8].…”

The author presents an approach to assist furniture engineers in generating multi-mode 3D exploded view automatically under the environment of AutoCAD platform. Based on the secondary development of AutoCAD with Visual LISP programming language, the approach proposed in this paper can allow users to generate 3D exploded view interactively, either centring on a fundamental part or just exploding the target parts. The automated procedure for generation of multi-mode 3D exploded view is explained and applied with a wooden armchair taken as example, obtaining feasible solutions.
