Design communication in immersive virtual environments: An initial exploration

Abstract: Using Virtual Environment (VE) to visualize ideas from the initial steps of design, the architect is challenged to deal with perception of space, solid and void, without translations to and from a two dimensional media. In this moment, we may expect new forms of design expression. The goal of our study was to identify how designers use and communicate early design ideas by using immersive three-dimensional VEs. We explored initial intentions of 3D-immersive design schemes, textual descriptions and collaborations within immersive VE. We setup a series of experiments including navigation-and perception-tasks, designing in immersive VE, transcription of design, remote communication between design partners and controlled observations. The paper describes these experiments. Finally we summarize observations from this research, for instance the simplicity to interconnect design-ideas cross platforms, conclude with possible future directions of our investigation, initiating a broader research including other disciplines.

BIM-PIM-CIM: The Challenges of Modelling Urban Design Behaviours Between Building and City Scales

Abstract: This paper discusses the challenges that designers face when modelling the anticipated behaviours of people: their movement and transactions around and within precinct scale development. Building Information Modelling (BIM) software philosophy contrasts with that of City Information Modelling (CIM)—the route by which we consider how precinct scale development, being somewhere between the two (BIM and CIM), requires a wholly different approach to information and behaviour modelling. The authors offer evidence of the value of augmenting the planners’ analytical approach with the architects’ synthesis from data leading to meaningful speculations on otherwise unanticipated future scenarios for the precinct far beyond expectation. Novel approaches to modelling behaviour at precinct scale suggest alternative readings of precincts, which require a wider set of approaches to Precinct Information Modelling (PIM) software development than simply an expansion of BIM.

Learning Through Structural Activity in Collaborative Computer-Aided Design

Abstract: The role of structural activities and other solution searching activities in design learning and problem solving have been identified in laboratory studies of problem solving and also in case studies of design teaching.. In laboratory studies, students have solved creative problems collaboratively under various communication conditions. The case studies follow students working on the same problem under two conditions – one group is taught using traditional face-to-face teaching while the other group is additionally supported by a textbased web board. This paper review findings from three experiments from which we can see that students producing above average solutions involved more structural activities than the mediocre cases. These successful cases engaged in textual expression of their design solutions. Computer tools for design should therefore support multiple representations of design work.

Fruitful Exchanges: Professional Implications for Computer-mediated Design

Abstract: The paper reviews experiences in using computer tools for collaborative design projects in the light of the lessons learned from implementing CAD systems in practice.

Problem Framing in Multiple Settings

Abstract: This study offers an insight to architectural students' problem framing activities using digital and paper media. The role of problem framing in design processes and its contribution to design learning has been studied by others. Here, we investigate the effects of media on framing activities. Laboratory experiments were conducted to investigate problem framing under three settings, namely online co-located, online remote and paper-based co-located. Student pairs were asked to spend forty minutes in solving collaboratively a wicked design problem. The results show that problem framing activities are significantly different in the online remote setting compared to those in the two co-located settings. We find more density of framing activities happened in the online remote setting than in the other two settings while there is no significant difference between online co-located and paper-based co- located settings.

Polymers for 3D Printing and Customized Additive Manufacturing

Abstract: Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining. AM enables decentralized fabrication of customized objects on demand by exploiting digital information storage and retrieval via the Internet. The ongoing transition from rapid prototyping to rapid manufacturing prompts new challenges for mechanical engineers and materials scientists alike. Because polymers are by far the most utilized class of materials for AM, this Review focuses on polymer processing and the development of polymers and advanced polymer systems specifically for AM. AM techniques covered include vat photopolymerization (stereolithography), powder bed fusion (SLS), material and binder jetting (inkjet and aerosol 3D printing), sheet lamination (LOM), extrusion (FDM, 3D dispensing, 3D fiber deposition, and 3D plotting), and 3D bioprinting....

A Review of Additive Manufacturing

Abstract: Additive manufacturing processes take the information from a computer-aided design (CAD) file that is later converted to a stereolithography (STL) file. In this process, the drawing made in the CAD software is approximated by triangles and sliced containing the information of each layer that is going to be printed. There is a discussion of the relevant additive manufacturing processes and their applications. The aerospace industry employs them because of the possibility of manufacturing lighter structures to reduce weight. Additive manufacturing is transforming the practice of medicine and making work easier for architects. In 2004, the Society of Manufacturing Engineers did a classification of the various technologies and there are at least four additional significant technologies in 2012. Studies are reviewed which were about the strength of products made in additive manufacturing processes. However, there is still a lot of work and research to be accomplished before additive manufacturing technologies become standard in the manufacturing industry because not every commonly used manufacturing material can be handled. The accuracy needs improvement to eliminate the necessity of a finishing process. The continuous and increasing growth experienced since the early days and the successful results up to the present time allow for optimism that additive manufacturing has a significant place in the future of manufacturing.
