Proportionate, well-defined sketches and renders communicate best. Pencil sketches done using good shade, shadow and highlight techniques or renderings in crayons, dry pastels, etc. are highly effective visualization tools for the designer.
Well thought of angles of view of the product, that gives maximum information about it, and covers most details are ideal. At times, you could also opt for more than one view, depending on your product, so as to communicate all aspects of your concept well.

• Take a simple object around you, say like a stapler and decide a relatively good angle, and sketch it in perspective, applying the basics you’ve learnt earlier.
Utilizing all the concepts discussed in the earlier chapters of this course, such as shadows, highlights, and the concepts of perspective, one can create very convincing product sketches and renders.
For rendering, one good technique is to select a base colour that comprises most part of the product’s body. This allows you to just play with the shadows and highlights, instead of bothering about the fill. Also observe how a reflection on an object will follow the contours of that object.
Reflections on Objects:
• Take a graph sheet and place a steel drinking glass on it, upside down and observe how the lines of the graph translate into curves when reflecting on the cylindrical surface.
• Sketch and render the same, as accurately as you can.
Good Product Rendering requires both practice and skill. Here is a variety of renders also done by the students at Industrial Design Centre, IIT Bombay.
• Gradually, take up more complex objects for rendering that demand greater detailing such as varied textures or materials, as elucidated by the examples above.
Memory Object Drawing and Rendering:
• The final challenge is to be able to accomplish convincing renders without any visual references.
• Begin with simpler objects like a bottle or drinking glass and graduate to complex ones, such as a camera or mobile phone.
• This will give you the confidence to draw relatively detailed objects from your own imagination.
