i. Drawing Paper
Drawing paper is the paper, on which drawing is to be made.
All engineering drawings are made on sheets of paper of
strictly defined sizes, which are set forth in the U.S.S.R
standards. The use of standard size saves paper and ensures
convenient storage of drawings. Now a day, A3 and A4 are
the most commonly used paper sizes. The U.S.S.R standard
establishes five preferred sizes for drawings as tabulated
