Isometric drawing

Focus task 1

• With this method of drawing, the object of the drawing is shown at right angles, viewed as from the front, and lines that represent the sides of the object drawn at a 45 degree angle to the left or the right.

How to do an isometric drawing:

1. Draw the front view of the object:

1. Draw feint construction lines at a 45 degree angle to the left or to the right to suggest depth:

1. Indicate the depth on the lines representing depth:

1. Complete the drawing:

Activity 2

Safety precautions in the classroom:

• Rules for safety are the most important aspect of any workshop. You must be thoroughly acquainted with the rules and safety measures that apply in your workshop. Ensure that you know what safety procedures have to be followed in case of an accident. Each learner must also know where the emergency switch and the first aid kit are located. Report every accident to your educator.

Note the following:

1. Clothing :

• Wear an apron or overall;
• Wear shoes;
• Tuck in ties and jewellery so that these items will not get in the way;
• Roll up long sleeves and tie hair to keep it out of the way.
• Behaviour :

• A workshop is no place for games;
• Do not run in a workshop;
• Never use a workshop on your own or without permission.
• Working safely :

• Use tools for the purpose for which they were designed;
• Put every tool away in the allocated place when you have finished using it;
• When carrying sharp-edged or pointed tools, hold them in such a way that the dangerous points or edges point towards the floor;
• Follow the instructions provided on machines;
• Wear safety goggles when working on machines;
• Report any faulty machines;
• See to it that machines are left in proper order when you finish working on them.

Safety measures for working with electricity follow in the module on electronics!

ACTIVITY 7

• Ensure that the learners are given sufficient opportunity to master this important drawing skill. Neatness is particularly important and the use of light construction lines and basic sketching skills (Activity 4) will enable the learner to meet these requirements.
