Drawing Layouts
Technical drawings have strict guidelines for the way drawings are laid out and arranged. These guidelines or conventions are set out by the International Standards Organisation (ISO) and Standards Australia (AS). This ensures that every designer produces drawings that can be read by every manufacturer, builder, assembler or user around the world.
Why do we need technical drawings?
Divide the class into groups. Elect someone in the group to be the head the designer and the remainder of the group to be junior designers, manufacturers, an assembler, an instructional / graphic designer, packager, a delivery courier, a marketing manager, a salesperson, and an end user. Line up in the order of the list of people involved in making and using the object or environment. The designer must design a product in their mind and describe it to the junior designers, the junior designers must then instruct the manufacturer who must pass it on the assembler and so on and so forth until it reaches the end user.
What product did you start with? What did the user indicate the design was?
Drawing Sheets
When drawing an instrumental drawing you will need to use an appropriately sized piece of paper. Most students chose A3 for convenience however, depending on the part being drawn; A4 or A2 are acceptable sizes. In accordance with Australian Standards, the image below shows the correct sizes for ISO A drawing sheets.
