Drawing Solids On A Flat Surface

Solid shapes can be drawn on a flat surface (like paper) realistically. We call this 2-D representation of a 3-D solid.

Oblique Sketches
An oblique sketch does not have proportional lengths. Still, it conveys all important aspects of the appearance of the solid.

Isometric Sketches
An isometric sketch is drawn on an isometric dot paper. In an isometric sketch of the solid, the measurements are kept proportional.

Visualising Solid Objects
Visualising solid shapes is a very useful skill. For this, the ability to see ‘hidden’ parts of the solid shape is required.
