Elective Part: Module 5
Visualisation and Computer-aided Design Modelling
Product visualisation and 3D modelling
To understand the application of sketch and Computer- aided Design system through the study of retail shop design
To understand the impacts and design considerations of shop branding and corporate image through market research
To understand the situation on the needs and uses of retail design through teamwork tasks and individual design assignments
Small group discussions and presentation
Apply creative thinking techniques to generate new ideas
Identify the needs of users and customers
Collect product information
Develop solutions modelled in appropriate materials to convey design concepts
Understand how ‘virtual’ prototypes for visualising design can enhance the product development process
Students should be made aware of the relevance of the technology they are studying to the real world. Case studies on technology and design enable students to put their learning into an authentic context, and so provide an additional resource that can add a new dimension to learning about technology and design.
Authentic Context: Students could explore the idea of visualisation and CAD modelling through the design process of a retail shop in Hong Kong
Strand 1 : Design and Innovation
Module 5 : Visualisation and Computer-aided Design (CAD) Modelling
Sketching is extremely important in the professional designer’s world for several reasons. As someone describes an idea to you, you get a picture in your mind. That picture is subjective, based on how you interpret words. A sketch visualizes the idea for the viewer, providing a shared visual experience that can be discussed, debated and refined.
Beyond communication, sketching is a way of thinking. Throwing lines down, doodling through a problem, we find new solutions. Through documenting that thinking in drawings, we go through the act of evaluating and building on thoughts until they are complete.
Three-dimensional computer model is a good example to explain how the sketching skill is important. While creating a computer model of one idea, the designer would flush out 50 concept sketches, meet with a group, refine the ideas, and do another round of finished concepts. A sketch is fluid. It implies to viewers that this is still a work in process, and they are freely to have input, brainstorm, and share ideas. A sketch has that perfect amount of communication and interpretation. When the concept reaches an optimal state, then it is the best time going to three-dimensional computer model.
1.2 The Essentials of AutoCAD
AutoCAD is a general purpose computer aided design (CAD) program to communicate and receive design ideas without ambiguity through basic knowledge and skill of preparing drawing and sketching. It also aims to visualise and standardise a wide range of presentation drawings for different professions; for instance, the architectural & interior design, engineering design, product design & manufacturing, multimedia production. However, the advantage of using CAD has hitherto been increasingly appreciated in decade over traditional manual drafting methods. It produces neater and more accurate drawing, and it provides faster rate of production. By selecting a variety of command in CAD program, users could apply different special drafting techniques. CAD also avoids the time-wasting and errors which possibly occurs in the repetition of drawing works.
1.3 Site Visit
Site visit is part of the quality evaluation process, which helps student to understand what markets do. Usually, it includes various activities, for instance, taking photo, drawing sketch, observing facilities, and interacting with staff, students and peer team review.
1.4 Researches and Analysis
Produce a research folder by collecting picture, photos, articles, charts and words from different media, for example, Internet, newspaper or magazine. Questionnaire is one of the research elements consisting of a series of questions and other clues for gathering information from the target group. Prepare about 30 to 50 sets and summarised the result by creating charts and words.
1.5 Branding and Corporate Image (CI)
See Appendix I
1.6 CAD Tutorial
The tutorials of CAD system are suggested to divide into four categories: 2D Basics, 2D Advance, Plotting Technique, 3D Modelling and Rendering. (Suggested computer software: Adobe Photoshop, Adobe Illustrator and Autodesk 3Ds Max.)
1) 2D Basics
1.7 More Exercises for CAD Visualisation Example 1: Measure the Site and Layout Plan exercise
Step One: By giving a set out plan, students are expected to measure the site in real space using measuring tape. It allows them to practice in the actual space.
Step Two: Students are required to construct a floor plan and practice various drawing and modify tools in AutoCAD.
Example 2: Coffee Table Design
Step One: The idea sketches show primitive designs of a coffee table.
Step Two:Finalizing the Ideas
Concepts were evaluated and the final idea is generated. Designer started concerning about the choice of materials.
Step Three:Construction Drawing Development
1) Use scale ruler to draw a coffee table with Top View, Side View and Sections on paper and mark actual dimension for the details.
2) To draw a coffee table by using AutoCAD in both Model Space and Paper Space for further development.
There are two modes of drawing in AutoCAD, both called "SPACE". The normal mode and the default are called "Model Space." This is the space you will always use and objects are always drawn in real world units (full size). The other mode is called "Paper Space", which allows only a 2-dimensional world, and can be visualized on a flat sheet of paper. Paper Space is a 2-dimensional drawing mode in which you can create various "views" of a 3-dimensional drawing in "holes" of the paper, which is called "viewports" for plotting. It is useful for plotting several views of an object at different scales, or for putting orthogonal drawing titles on a perspective or axonometric drawing.
Model Space – For creating real world size drawing
Paper Space – For producing 2-dimensional drawing in different scales.
