TOPIC: BOARD PRACTICE
Sub- Topic
- Basic board practice; setting drawing paper on the board
- Sharpening pencil to conical point and knife edge.
Sub-Topic II: Setting Drawing Paper on the Board
Step 1: The drawing board is conveniently placed on the table with the paper on the board, leaving equal size all rounds, with the Tee-square edge to the left-hand side.
Step 2: Place the tee-square on the paper and gently move or slide the tee-square to the top edge of the paper. Set the top edge of the paper parallel to the edge of the tee-square with the stock of the tee-square firmly against the edge of the drawing board on the left-hand side.
Step 3: Hold the paper with four pieces of adhesive tape or two metal cups to hold the paper in position at four corners.
Step 4: Gently slide the tee-square down without moving the paper.
Sub-Topic III: Sharpening of Drawing Pencils to conical point and knife edge
A well sharpened pencil is very essential to technical drawing. Pencils for lettering and freehand sketching should be sharpened to a ‘conical point’ while those for geometrical or engineering drawing should be sharpened to a ‘chisel point’.
