Drawing Isometric Blocks With Freehand
Freehand sketching is a method of drawing object without the use of drawing materials except a pencil. Students should try as much as possible to attempt drawing isometric blocks with freehand. It may seem difficult in the beginning but with constant practice, good results will be achieved.
In technical drawing, a freehand sketch is made in exactly the same way as drawing done with instruments. AOX is drawn first, then, the measurement is transferred; constant practice will also help you to achieve good proportion.
