FIXING THE DRAWING SHEET
Drawing sheet should be fixed on the board in. such a way that its upper longer side is
truly horizontal. First of all the sheet -is placed on the board such that approximately equal spaces are left on all the sides. T-square is placed over the sheet and is held in the correct position with the left hand as described before, so that, its blade comes in a horizontal line. It is then slided up until its working edge comes very near to the top edge of the sheet. The drawing sheet is now adjusted from below with the right hand without disturbing the-T-square until its top edge becomes parallel to the working edge of blade of the T-square. The T-square is then slided a little downwards and the sheet is fastened to the. board on the two upper corners with the help of drafting tap. The T-square is then slided up and edge of thesheet is again checked. If it is exactly horizontal, the T-square is slided down until it is just above the bottom of the sheet and tape is applied over the lower corners. Drafting tap is preferred for fixing the sheet on the board because it does not damage the board and it will not damage the sheet if it is carefully removed by pulling it off slowly towards the edge of the paper.
