There is a growing interest in the discipline of design sketching and drawing. Whereas its origin lies in the sketching and presenting of tangible (industrially designed) products, the discipline has, since approximately 2010, extended in various ways, along various dimensions. Various authors have addressed and discussed the most prominent change within the discipline since: the addition of so-called ‘story telling visuals’: sketches of processes, overviews, systems and e.g. journeys (Corremans and Mulder-Nijkamp 2019, Hoftijzer, Sypesteyn et al. 2020), also named ‘visual thinking’. In fact, sketching as a means of communication has grown across discipline borders, and, consequently, the activity of sketching for communication enjoys a growing group of actors and audience these days. The authors, being sketching practitioners and teachers, have been developing sketching course content aligned to this, both for the extending discipline (Bachelor and Master courses) of sketching within Industrial Design and for new audiences. One particular course, a so-called ‘Master Class’, which is an intensive two-day taking course to an external audience, focused on ‘how to sketch visual stories’, was subject to an experiment. Firstly, the course was designed according to specific requirements (audience, goals, pedagogy) and to previous insights of course development and evaluation, of workshops offered, and according to previously described vision and methodology that concerns the alignment between sketches of tangible things and sketches of abstract concepts (Hoftijzer, Sypesteyn et al. 2020). Secondly, in order to assess the logic and quality of the short course’s structure and contents, participants were asked to fill out a questionnaire. Together, this experimental set-up, the questionnaire results, and the sketched output of the Master Class have led to new insights, to new knowledge that will help improve the pedagogic approach of many of the current courses taught and to the follow up Master Class in particular.@en

Today's global context of mass-produced items has resulted in an increasing 'distance', or alienation, between people and the origins of the items they buy and use: an unhealthy human-product relationship. This observation permits the search for an alternative interpretation of well-being: a transformation that would support resilience and self sufficiency, and a better human product relationship or 'a new partnership', as advocated by various scholars. In this paper, this new partnership is considered through supporting 'Do-It-Yourself' (DIY) product design: a scenario in which professional designers facilitate laypersons to design for themselves. Anticipating (1) the designer's responsibility, and (2) the layperson's innate desire to create, this paper introduces a 'Design for DIY' framework method to help bridge the knowledge gap between the product designer and the layperson. The initial starting points of this study, complemented by a range of 'Design for DIY' studies, and an exploration of existing design frameworks and design models, resulted in the design of a 'Design-for-DIY' framework. This paper concludes with recommendations for the testing and further development of the Design-for-DIY framework.

Digital technologies have enabled design sketching to expand into new applications and domains. Inevitably, these new forms of visualisation require re-evaluating how we use drawing to see, visualise, understand, and fabricate products and services in design education and the profession. This paper presents a selection of discoveries after the authors performed research, made presentations and mediated workshops when face-to-face collaborations and travel were impossible because of the Covid-19 epidemic restrictions. Findings add to work intending to build a modern taxonomy for design sketching and visual knowledge while accounting for immersive virtual collaboration and distributed workflows from sketching to 3D CAD and 3D printing. These are among the first indications of a drive towards synthesising historically demarked design process stages into a singularity of actions that merge and move simultaneously among ideation, design, and production. Participants in two international conference workshops shared ideas and discussed their local circumstances relating to the potential use and acceptance of new technologies already researched and adopted in other disciplines such as computer science and entertainment. A critical consensus was that the challenge of new technologies for our design education and profession is not as much about technology and its tools as the process and steps that enable change. Significantly, conversation pointed towards a strategy that enhances and augments habits in design education and the profession as the means to modify and transform culture and practice.

A new analysis of design sketches for the design of the Quinny Hubb strawler, by Vanderveer Designers, was executed to validate and/or complement the existing typology of design sketch factors and outcome characteristics, as described by Hoftijzer et al (2018).@en

Product designers extensively use sketches to create and communicate 3D shapes and thus form an ideal audience for sketch-based modeling, nonphotorealistic rendering and sketch filtering. However, sketching requires significant expertise and time, making design sketches a scarce resource for the research community. We introduce OpenSketch, a dataset of product design sketches aimed at offering a rich source of information for a variety of computer-aided design tasks. OpenSketch contains more than 400 sketches representing 12 man-made objects drawn by 7 to 15 product designers of varying expertise. We provided participants with front, side and top views of these objects, and instructed them to draw from two novel perspective viewpoints. This drawing task forces designers to construct the shape from their mental vision rather than directly copy what they see. They achieve this task by employing a variety of sketching techniques and methods not observed in prior datasets. Together with industrial design teachers, we distilled a taxonomy of line types and used it to label each stroke of the 214 sketches drawn from one of the two viewpoints. While some of these lines have long been known in computer graphics, others remain to be reproduced algorithmically or exploited for shape inference. In addition, we also asked participants to produce clean presentation drawings from each of their sketches, resulting in aligned pairs of drawings of different styles. Finally, we registered each sketch to its reference 3D model by annotating sparse correspondences. We provide an analysis of our annotated sketches, which reveals systematic drawing strategies over time and shapes, as well as a positive correlation between presence of construction lines and accuracy. Our sketches, in combination with provided annotations, form challenging benchmarks for existing algorithms as well as a great source of inspiration for future developments.We illustrate the versatility of our data by using it to test a 3D reconstruction deep network trained on synthetic drawings, as well as to train a filtering network to convert concept sketches into presentation drawings.

Within the field of industrial design, sketches play a significant role for communication. Sketching represents a language for designers to explore options and support creativity, and to express visions and solutions to teams, clients and other stakeholders. Considering the many different goals and formats professional sketches (and visualisations in general) have in practice, this paper suggests to also explicitly distinguish and teach the various factors that should be taken into account for each specific type of sketch: uncover why sketches look the way the look. Several authors have in the past described classifications of design sketches and drawings, mostly assigned to specific design stages. However these scholars do not specifically describe the communication factors, nor do they provide clues or guidelines for implementation. The case study on which the research was based was executed in close collaboration between University and Dutch design agency Vanderveer Designers, it concerned the Thule Yepp Nexxt child bike seat project they ran, which was awarded with the ‘best of the best’ Red Dot Award and the IF Gold award. The case study has helped to conclude that sketches vary along an extensive range of dimensional axes. Further, the visual database of sketches helped to uncover the various characteristics sketches could have. Correlating (1) specific sketches with (2) the factors defining them and (3) the outcome characteristics together will help students and designers, agencies and clients to better understand and interpret each other.@en

The technological changes that concern the tools for making have an effect on the type of profession designers will have in the near future. The traditional ‘industrial’ relationships between suppliers, manufacturers, designers and users alter rapidly, causing business models to change as a consequence [Beyond the Brand: Why Engaging the Right Customers Is Essential to Winning in Business, Dearborn Trade Publishing, 2004; MCPC: World Conference on Mass Customization, Personalization, and Co-Creation 2011, San Francisco Airport Marriott Waterfront, 2011], as many economic principles seem to be no longer valid [NV Weekblad De Groene Amsterdammer, De Groene Amsterdammer, Amsterdam, 2015]. While many education programs prepare students for a future in a traditional user–supplier relationship context, anticipating the recent changes should probably be considered [Open Design Now, BIS Publishers, Amsterdam, 2011].

The extended process of ‘design for DIY’, that is facilitating non-designers to design and make an object or tool for themselves, by creating a suitable platform and design environment, includes a range of extra design steps, compared to traditional product design. (1) The pre-design stage, including setting the objectives, anticipating the audience, and the initial product design that is to be adapted; (2) establishing the design environment (including platform, inspiration, etc.); (3) designing the interaction between facilitator and amateur with the help of the design kit; (4) The final ‘translation phase’, in which the amateur design result is to be prepared for fabrication. The order in which these steps can be taken varies.

As part of a running research project, a small series of ‘design for DIY’ experiments has been executed, that helped testing specific approaches of how to facilitate amateurs. These test runs resulted in some very interesting insights regarding the exchange of information between facilitator and amateur, and regarding preferences and skills amateurs revealed to have. Conclusions from these experiments help to define the area of expertise that should preferably be integrated into (university) design curricula and will help to further establish a framework for ‘Design for DIY’ (DfDIY). These experiments help indicate the changing of the design profession caused by technological and societal changes and, most importantly, how to anticipate.@en

The activity of drawing has characterized the human being since pre-historic times. The ‘language’ of drawing was utilized long before writing was there. It is an expression of human’s unique creativity and an example of human’s near-exclusive usage of tools. In this paper, the broad definition and relevance of drawing will be addressed first. Subsequently, the position of the professional and educational field of design drawing takes will be discussed, and its specific functions within the context of product design. The overall goal of this paper is to summarize the various uses of drawing as a ‘design language’, discuss the educational value and present a preliminary learning model, which describes the sequential and additional steps that need to be taken into account when teaching students how to draw. The variety of functions of the drawing medium are integrated in the so-called design drawing curriculum of the Industrial Design Engineering program at the Delft University of Technology, which will be elaborated on. Subsequently, as an exemplifying and representative approach for suggesting an object’s volume - one of the most important goals of design drawing – a specific method and technique will be described and shown.@en

Since the field of industrial design to a great extend concerns the creative development of threedimensional objects, project communication is often a visual matter. The activity of design drawing enables to visually suggest ideas and solutions that don’t exist yet. Drawing sharpens observation, increases perception and support visual imagination, is how art historian Buser describes it [1]. This paper will explore and discuss a specific drawing tool that seems to be suitable to utilize in various stages of the design process, and to a wide range of functional practices and educational exercises of design drawing. This drawing technique – applying scraped pastel powder to drawings – facilitates the visual depiction of an object’s volume, and of the spaciousness of a certain scene. Besides, because of the pastel powder’s smooth effect, it is also very suitable to very lightly and gradually describe a surface with a certain curvature or shininess (reflecting the sky). Further, because of the remarkable similarities between the analogue pastel technique and the digital airbrush (e.g. in Photoshop), the pastel tool serves as a very helpful tool and technique to prepare students for the digital medium. For educational purposes, this paper will discuss the use and suitability of powdered pastel as a drawing tool, by evaluating its implementation in a range of specific drawing education exercises. These drawing exercises correspond to and represent the visualization of various design stages and subjects.@en
