Abstract

Despite the availability of Computer-Aided Design (CAD) systems, paper-based sketching is still widely used during conceptual design due to its efficiency in externalizing form solutions. The main reason attributed to this is that the user-interface of most CAD systems follows the WIMP (Windows, Icons, Menus and Pointing device) paradigm which does not support freehand form sketching as input on normal paper. Yet CAD systems still offer advantages for early form design such as threedimensional (3D) model visualization. Thus designers would greatly benefit if the advantages of manual sketching are combined with those of CAD. However, due to various factors, such as the idiosyncratic style of sketching, computer processing of handmade sketches becomes difficult. At the same time, although drawing standards are available for detail design, standards for early form sketching are unavailable. To address the above issues, this paper reports ongoing research aimed at providing a drawing standard to seamlessly link early form sketching on paper with 3D modelling technology. The paper provides an overall picture of the state-of-the-art approaches to early form sketching. A drawing standard has been developed to address the identified deficiencies of current approaches. The developed standard specifies what is required both for the process of drawing and the representation of form in the resulting drawing, i.e. the early form sketch. Besides from providing 3D models directly from paper sketches, such a standard has been found useful for collaborative design. Evaluation results indicate what aspects of the proposed drawing standard require improvements.

Hybrid Sketching: A New Middle Ground Between 2- and 3-D
John Alex

This thesis investigates the geometric representation of ideas during the early stages of design. When a designer's ideas are still in gestation, the exploration of form is more important than its precise specification. Digital modelers facilitate such exploration, but only for forms built with discrete collections of high-level geometric primitives; we introduce techniques that operate on designers' medium of choice, 2-D sketches. Designers' explorations also shift between 2-D and 3-D, yet 3-D form must also be specified with these high-level primitives, requiring an entirely different mindset from 2-D sketching. We introduce a new approach to transform existing 2-D sketches directly into a new kind of sketch-like 3-D model. Finally, we present a novel sketching technique that removes the distinction between 2-D and 3-D altogether.

A review of product sketching in early phases of design
Dibakar Sen

2009

Sketching has been the chosen method of expression of product ideas in the initial phase of product design. Existing CAD modeling systems do not support the early phases of design effectively. There has been growing interest to integrate sketching and 3D modeling mainly because of recent developments in interfaces like motion trackers and haptic devices. The paper reviews the state of the art literature in the areas of conceptual design and sketching, 3D shape creation and visualization, sketch based modeling and sketch recognition to understand the scope of 3D sketching in the design process. It is observed that the majority of the literatures focus on creation of 3D models by interpreting 2D sketch strokes. Sketching behavior of the designer, while creating sketches directly in 3D needs detailed study.

Knowledge Intensive ‘Paper-Based’ Form Sketching
Jonathan C Borg

Knowledge Intensive Design Technology, 2004

The research reported in this paper concerns the ongoing development of a Knowledge Intensive Sketching (KiS) framework through which designers are supported in foreseeing directly from their paper-based sketches the relevant life-cycle consequences of their 'component form' solution concepts. The goal of the KiS framework is to retain the important characteristics of freehand sketching, i.e. pencil and paper, whilst at the same time exploit the benefits of Knowledge Intensive CAD technology for proactively guiding designers in generating life-oriented solutions as from early design.

A Comparison Study: Sketch-Based Interfaces versus WIMP Interfaces in Three Dimensional Modeling Tasks
Alex S Gomes

Sketch-Based Interfaces are becoming a popular interaction style for many applications. The interaction style tries to recreate the experience of sketching that is similar to real paper and pencil drawings.They are being used to accomplish tasks related to geometric modeling, animation, architecture, design, music, and learning, among others. In this work we evaluate and compare two interaction approaches, Sketch and WIMP, in tasks for modeling 3D objects. We used two distinct tools: Teddy - a sketch based modeling software, and the more traditional WIMP modeling tools Maya & 3DS Max. We used quantitative and qualitative methods to identify benefits from both techniques from the users' perspective. These data will be turned into requirements for a future prototype based on the usability gains of a combination between the two approaches in study.

An Evaluation of a Language for Paper-based Form Sketching
Kenneth Camilleri

2006

Designers still sketch on paper to externalize their early form concepts. The user-interface of current Computer-Aided Geometric Modelling (CAGM) systems lacks the fluidity of sketching. Yet, such systems are still useful in conceptual design since they assist designers in visualizing an evolving form idea. The research disclosed in this paper is aimed at combining the benefits of paper-based freehand sketches with those of three-dimensional (3D) models. More specifically, this paper reports the on-going development of a prescribed sketching language (PSL) required to create a seamless link between paper-based form sketching and CAGM systems. Evaluation results revealed that whilst PSL is easy-to-learn, yet it requires improvements. Such a sketching language contributes a step towards simulating early form design solutions by the combined use of paper-based sketches and 3D models.

Investigating three-dimensional sketching for early conceptual design - Results from expert discussions and user studies
Johann Habakuk Israel

Computers & Graphics, 2009

As immersive 3D user interfaces reach broader acceptance, their use as sketching media is attracting both commercial and academic interests. So far, little is known about user requirements and cognitive aspects of immersive 3D sketching. Also the latter's integration into the workflow of virtual product development is far from being solved.

Computer-aided sketching to capture preliminary design
Mark Apperley

Australian Computer Science …, 2002

This paper describes the vital role of freehand sketching in the design process. When designers first tackle a design problem they usually do so by sketching. We will explore the essential elements of sketching that make it so helpful to problem solving. We then examine how current computer interfaces interfere with the sketching process, and go on to establish the requirements for an environment to support sketching. Finally we describe a system under development to integrate sketching into a visual programming environment (Visual Basic) . .

A Study of Usability of Sketching Tools Aimed at Supporting Prescriptive Sketches
Manuel Contero, Ferran Naya, Pedro Company

2006

Prescriptive sketches are usually drawn, after conceptual design is over, to prepare the creation of digital 3D models. Designers and draftsmen use them as "screenplays" that guide the creation of the final 3D model. Prescriptive sketches are still paper-and-pencil, in spite of the existence of some academic or even commercial, computer tools. In this paper, we defend the hypothesis that this is because current computer tools are less usable than paper-andpencil sketches and do not posses significantly improved functionality. A pilot study was conducted to validate this hypothesis. Both the study and its main conclusions are described in detail.

Structural Sketcher - Representing and Applying Well-Structured Graphic Representations in Early Design
Henri Achten

(TU Eindhoven paper) Computational drawing support is one avenue to improve design support in the early phase. Much work in this area is devoted to input of design information, manipulation, and presentation. Based on a review of current work, we note that among other things, drawing tools should be close to the conventions and styles used by architects. This is in principle possible by processing strokes in a more or less traditional sketch approach, or by offering specialised commands that provide a direct implementation of such conventions. The latter approach is covered by Structural Sketcher. A subset of drawing conventions developed earlier, called graphic units, is adopted for the system. In order to contribute to design support, the application of such graphic units should be fast and intuitive, and the definition of internal relationships should be easy and fast. For intuitive manipulation, Structural Sketcher incorporates the “paper and sciccors” metaphor, and introduces a novel UI-concept called the KITE. For easy and fast maintaining of relationships, a graph based on anchor-points is built-up on the fly. Performance of the system has been tested on a quantitative and qualitative basis. The system shows the benefit that graphic units can bring to drawing support, and how these can be implemented. To conclude, limitations and further work are discussed.
