Lesson Content

Drawing Instruments: Board in technical drawing and

In technical drawing, the board is one of the most important instruments. It is a flat, rectangular surface used to hold the drawing paper securely while drawing. The board ensures that the paper remains flat and steady, which is crucial for accuracy in technical drawing.

Board Practice Procedures:

Set Up the Board: Place the drawing board on a stable surface. Ensure it is clean and free of dust or debris.
Position the Paper: Use clips or tape to secure the drawing paper onto the board. The paper should be aligned correctly with the board’s edges.
Use of T-Square: Place the T-square along the edge of the board to draw straight horizontal lines.
Utilize Set Squares: Use set squares for drawing perpendicular or angled lines on the paper.
Drawing with Precision: Ensure your pencil is sharp, and draw lightly to avoid mistakes. Press gently to make lines clean and visible.

Lesson Evaluation

To evaluate the learning, the teacher asks pupils to:

Define a board in technical drawing.

List the materials needed to set up a drawing board.
Describe the steps involved in board practice.
Explain the importance of using a T-square in technical drawing.
Show how to use set squares for drawing different angles.
