The wooden strips are cleated at the back by two battens by means of screws to prevent warping. One of the shorter edges of the rectangular board is fitted with a perfectly straight ebony strip. This edge is used as working edge for the T-square, which moves against the ebony edge.  \nFollowings are the standard sizes ofthe drawing boards according to the Indian Standard Institution (I. S. I)  \nFigure 1: Drawing board  \n\n| Sl.

Depending upon the nature of the drawing the qualities of drawing papers are selected. The drawing paper should be of uniform thickness and of such quality that erasing should not have leave any impression on it. One of the sides of the drawing paper is usually rough and the other smooth. The smooth surface is the side for the drawing work.  \n4  \nDrawing sheets of different sizes are available. Figure 2 shows the drawing sheets of various sizes such as A0, A 1, A2, A3, A4 and A5 according to the Indian Standard Institution (I.S.I) . The standard sizes of trimmed and untrimmed drawing sheets according to the Indian Standard Institution (I.S.I) are given in the Table 2.  \n\n| Size A0\u003Cbr>(841 x 1189) |  |  |  |\n| --- | --- | --- | --- |\n| Size A1\u003Cbr>(594 x 841) | Size A2\u003Cbr>(420 x 594) |  |  |\n|  | Size A3\u003Cbr>(297 x 420) | Size A4\u003Cbr>(210 x 297) |  |\n|  |  |  |  |\n\nSize A5  \n148 x 210  \nFigure 2: Standard size of drawing sheets according to I.S.I  \n5  \nTable 2: Standard sizes of trimmed and untrimmed drawing sheets  \n\n| Sl.

T-square  \nT-square is made of hard quality wood such as teak or mahogany, etc. These are two essential parts of Tsquare, namely stock and blade. The blade is fitted with an ebony or plastic piece to form working edge of T-square.
