Sketching is a quick drawing done without detail using only pencil and paper. It is used to capture initial ideas, refine concepts, and communicate technical information visually. There are five basic symbols used in sketching: points, lines, surfaces, planes, and textures. Sketches can be used for nine reasons including persuading decisions, developing proposals, clarifying complex ideas, and analyzing design methods. There are five types of sketches for different purposes and lifespans, such as rough sketches, refined sketches, presentation sketches, temporary sketches, and permanent sketches.
Sketching
- 2. What is a sketch? • In the most basic sense, a sketch is a drawing that is done quickly, without great detail and with only pencil and paper. • The advantage of sketching: since only a few materials are needed, sketches maybe done anywhere.
- 3. Materials Used • Paper used includes: • plain paper or newsprint • graph paper to help maintain proportion and scale • Tracing paper • Pencils and erasers • Do not use drawing tools
- 4. More on sketching • Good sketching techniques are used to capture initial ideas. • In addition, they are used to refine ideas and communicated technical information. • 5 basic, visual symbols are used • There are nine reasons to sketch • There are 5 types of sketches
- 5. 5 Basic, Visual Symbols • Point: symbol that is used to describe a location in space • Line: path between 2 points • Surface: flat or non-flat element created from curved lines • Plane: a flat surface • Texture: Surface quality
- 6. Reasons to Sketch 1. Persuade people who make decisions 2. Develop a refined sketch of a proposal 3. To clarify a complicated idea 4. To give design idea to drafters 5. To develop a series of ideas for refining a new product or part.
- 7. Reasons to Sketch 6. To analyze or develop best methods and materials for a part 7. Record permanently a design improvement on a part that already exists 8. To show that there are many ways to look at or solve a problem 9. To spend less time on drawing
- 8. Types of Sketches • The type of sketch to be used depends on the purpose of the sketch and on the intended lifespan of it. • The sketcher needs to take in to consideration who will be using the drawing and for how long the drawing will be used.
- 9. Rough Sketches • Drawn quickly using jagged lines • Primary purpose is to express ideas or thought quickly • Tools are not used • Attention is focused on proportion • Notes or labels are added as needed
- 10. Refined Sketches • Drawn more carefully than a rough sketch • Have better line quality than a rough sketch • Better proportion • Use basic tools such as straight edges and templates
- 11. Presentation Sketches • More refined than a refined sketch • Used to convince management or clients to accept or approve ideas • Usually shown in an eye-appealing 3- dimensional view to appeal to non-technical people
- 12. Temporary Sketches • Done to solve an immediate problem • Usually thrown away when no longer needed
- 13. Permanent Sketches • Usually kept as part of the record (legal document) • Attached to files or memos
- 14. Overlays • An overlay is a piece of translucent paper used to trace over drawings • Has three primary purposes: 1. Reshaping an idea 2. Refining a drawing without really changing it 3. Add various options to a basic drawing
- 15. Terms to Know • Visualize: To picture in the mind’s eye what something looks like • Implementation: To draw or create an object after it has been visualized Ed visualized how to fix the stairs and then implemented his plan.
