Shapes

2D planar objects.Eg of simple shapes: square, circle,

triangle, etc.

Composite shapes: Combining simpleshapes.

Three-dimensional Isometric

We usually start by sketching cuboids toprovide the necessary framework.

The blocks also provide a sense ofproportion to the object you design.

Selection of Isometric Axes

An isometric view should reveal as much

detail as possible such as in view (a)

Sketching Isometric Circles

Remember:

A circle looks likean ellipse on anisoplane

Building Piece Up One Block

At a Time

Use the block method to sketch the lower block

Complete the upper block

The blocks can be used as frameworks tosketch organic shape object.

Remove

thin lines

and render

surfaces

Create frameworks or boundary ofproduct with isometric boxes toachieve good proportion

Use light and thin lines (pencil)

Try to sketch productprofiles within isometricboxes

Use thick uniform lines(permanent marker)..mayuse pencil first if notconfident.

Colour your 3D form..

You need not block out all features of your ideas.

You may just need to block the base features.

Minor details and features can be

drawn directly (ie. Without blocks)

Now sketch theblocks of thisincubator

Suggested solution. You can come up with many other forms!

Remove frameworks and adddetails on your basesketches.

Notice how theframework providesthe guides for your 3Dforms.

Can you change the form of

an existing products?

Start by transformingexisting products into

frameworks consisting ofisometric boxes. Ignoringdetails (e.g labels) .
