TITLE : APPLICATION OF AUTOCAD PACKAGE IN TECHNICAL AND
ELECTRICAL DRAWINGS
COURSE LEARNING OUTCOME:
CLO 5: Produce with precision the drawings of graphics, electronic circuits
schematics and electrical wiring layout diagrams faster and neat.
OBJECTIVES: The students should be able to:
1. Draw accurately and neatly electrical wiring layout plan for home, office
or at any specified space.
2. Make use of the AutoCAD commands such as the Draw, Edit, Drawing
Aid commands skillfully to produce technical drawings.
EQUIPMENT : 1. Desktop Computer/Laptop
2. AutoCAD 2004 software
3. Printer for A3/A4 (Black/Color)
PROCEDURE:
1. Create a new drawing space using the Metric measurement.
2. Set the drawing limits to A4 paper size.
3. Display the grid to the extent of the drawing limits.
4. Create layers and rename the layers as below:
i. Border
ii. Plan Layout
iii. Dimension
iv. Electrical Wiring Layout
v. Schematic
vi. Legend
5. Make layer Border as the current layer and redraw to full scale size Fig 12.1

6. Refer to Fig. 12.2.
Make the layer Plan Layout as the current layer and draw the Plan Layout of
the home and name each area/space/room.
Make layer dimension as the current layer and place dimensions to the plan
layout.
Make the layer Electrical Wiring as the current layer and draw the electrical
components and the wiring layout.
Make the layer Schematic as the current layer and draw the schematic circuit
as in Fig. 12.3.
Make the Layer Legend as the current layer and redraw the diagram /symbols
as in Table 12.1.
7. Print out the drawing file as follows:
i. Layers Border and Plan Layout.
ii. Layers Border, Plan Layout and Dimension.
iii. Layers Border, Plan Layout and Electrical Wiring.
iv. Layers Border, Schematic and Legend.
8. Save the drawing file and exit AutoCAD.
