This document provides instructions for a practical evaluation in a computer aided design course. Students are asked to use AutoCAD to accurately draw an electronic schematic circuit. They must set the drawing limits and grid, create layers for different circuit elements, insert block components from another file, add wiring and text labels to the appropriate layers, and print the final drawing in stages. The objectives are to learn how to produce electronic schematic drawings and make use of AutoCAD commands efficiently. Upon completion, students must provide a reflection on what they learned.

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 electronic schematic drawings.
2. Insert Block drawings from other drawing files and make use of the
Explode command to break block drawings into individual entities.
3. 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
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 all drawing limits.
4. Create layers and rename the layers as below:
i. Border
ii. Components
iii. Schematic Wiring
iv. Text
5. Make the layer Border as the current layer and redraw Fig. 11.1.

6. Refer to Fig. 11.2:
 Make the layer Components as the current layer.
Using the Insert command, insert the basic electronic components from the
‘Basic Electronics’ file into the drawing space and rearrange the
components.
 Make layer Schematic Wiring as the current layer and make the wiring
connections.
 Make layer Text as the current layer and rewrite the numerical and
component values of the components respectively.
7. Print the drawing file as follows:
i. Layer Border.
ii. Layers Border and Components.
iii. Laers Border, Components and Schematic Wiring.
iv. Layers Border, Components, Schematic Wiring and Text.
8. Save the drawing file and exit AutoCAD.
