Saund (Editors)  \nA Prototype Sketch-Based Architectural Design System with Behavior Mode  \nJun Yu and Hao Zhang†  \nGrUVi lab, School of Computing Science, Simon Fraser University, Burnaby, Canada  \nAbstract  \nWidely used for architectural design, CAD systems such as AutoCAD, provide powerful modeling functionalities. However, they are often too complex for an architect to use, especially during the conceptual design stage involving primarily sketching of ideas. Also, interactions are typically driven by mouse and keyboard, but these devices cannot be used as freely as a pencil. For an architect, a tablet PC with stylus provides an ideal interface. In this paper, we study sketch-based architectural design and modeling and a prototype system which respects simplicity and human behavior mode (i.e., “our natural habits of doing things”) is described. Our system provides a seamlessly integrated design/draw environment with intuitive and focused interaction built in, both in an attempt to provide a design environment that closely conforms to the architects ’ design habits. As a proof of concept, traditional PC is still used and the stylus is simulated by a mouse, which is responsible for all system operations.  \nCategories and Subject Descriptors (according to ACM CCS): I.3.5 [Computational Geometry and Object Modeling]: Modeling packages  \n1. Introduction  \nArchitecture is the art and science of designing buildings and structures. The role of the architect, although constantly evolving, has been central to the design and implementation of the environments in which we live. Although architectures, as thinking products of the architects, are almost exclusively 3D entities, their initial conception has always come from the architects’ drawing papers, typically through the use of freehand sketches by a pencil; the 2D drawing papers are the architects’ design environment.  \nTraditionally, architects draw perspective pictures to evaluate, refine or exhibit their designs. This is a time-consuming task and not every architect is an expert on perspective drawing. Even if the drawing comes from a skilled architect or artist, the problem of perspective distortion typically occurs in every hand-drawn picture. With the rapid advancesin computer-aided design, computer graphics, and humancomputer interaction techniques, more and more computerbased systems have appeared in the field of architectural de-  \n† [yujuny@cs.sfu.ca](yujuny@cs.sfu.ca), [haoz@cs.sfu.ca](haoz@cs.sfu.ca)  \nsign and modeling. These software products aim to extend the architects’ ability to express, to communicate, and to experiment, utilizing their creativity in a fuller extent.  \nThere is little doubt that architectural design in the future needs to seamlessly integrate the architects into the digital modeling work-flow, the realization of such a goal however presents many challenges. As nicely put in a statement [Gre00] given by the “Technology for Education”project, one such challenge lies in the early design stage:  \n“Although much progress has been made at the rendering stage, architectural modeling, particularly at the early stages of design, represents one of the most difficult challenges for the interactive graphics software industry. Currently, available architectural design software is difficult to use at the preliminary design phase. Most offerings are derived from two-dimensional drafting systems requiring precise input. What is needed is a ‘back-of-the-envelope’ environment, with the ability to sketch, doodle, and erase, to proceed in an iterative, non-linear fashion, and to perform these operations ina full three-dimensional domain. Since design is an iterative process and it is frequently necessary to work  \nsubmitted to EUROGRAPHICS Workshop on Sketch-Based Interfaces and Modeling  \n2 Jun Yu & Hao Zhang / A Prototype Sketch-Based Architectural DesignSystem with Beha","cbCaigf22gQKZIsp","https://ap.wps.com/l/cbCaigf22gQKZIsp","pdf",478601,"English","# Introduction\n## Sketching in 2D and modeling workflow\n## Limitations of traditional CAD interaction\n## Motivation for a simplified sketch-based system","[{\"question\":\"Why are current CAD systems difficult to use in early architectural design?\",\"answer\":\"They are typically complex and rely on precise 2D drafting inputs, which do not match the iterative, non-linear nature of conceptual sketching.\"},{\"question\":\"What interface approach does the paper propose for architects?\",\"answer\":\"A tablet PC with stylus is treated as an ideal pencil-like interface, and the prototype system integrates intuitive sketching, assembly, and modification operations.\"},{\"question\":\"How does the prototype system handle the stylus concept in the proof of concept?\",\"answer\":\"Traditional PC is kept, while the stylus is simulated by a mouse to perform system operations.\"}]","A Prototype Sketch-Based Architectural Design System with Behavior Mode | PDF",18]
