  3. Standards Paper Sizes The ISO most recommended paper sizes for technical drawings are known as A-FORMATS. Other series, like the B-Series, are of lesser importance. In the A-Format series, the largest size is A0. The size of an A1 paper is half the size of A0 while A2 is half the size of A1 and so forth.. For technical drawings A4 is considered to be the smallest paper size. Smaller-sized AFormat papers (i.e. A5, A6, etc) are very rarely used for technical drawings. Computer Aided Engineering Drawing

  4. The A-Format Paper Sizes When a format smaller than A4 is needed, it is obtained by simply halving A$ along its longer side. For instance A5 has 210-mm as its longer side and (297/2 = 148- mm) as its shorter side. . Format A4 is exclusively used in an upright position. The other formats (which are lager in size than A4) may be used in an upright position or horizontal position. . Computer Aided Engineering Drawing

  5. Title Block In every engineering drawing, a Title Block is included at the bottom (right-hand corner). The Title Blocks are locally standardized but should be designed in such a way that it can be easily understood. The information needed in any standard Title Block is normally: .

  7. Basic Instruments and Equipment T-Square This is one of the oldest drawing instruments that still finds wide spread use both in the industry and in schools. The size of a T-Square is determined by its blade length. Blade lengths of 60-mm, 90-mm, 120- mm and 150-mm are common. USES: The T-Square is used primarily as a guide for drawing horizontal parallel lines. Computer Aided Engineering Drawing

  8. Set Square Set Squares (SSs) are transparent, triangular-shaped drawing instruments that are used with a T-Square for drawing vertical or inclined lines. SSs contain angles most commonly used in technical drawing, i.e. 30, 45, 60 and 90. The height/length of SSs is typically 15-cm, 20-cm, and 25-cm. Computer Aided Engineering Drawing

  11. Line Types In Engineering Drawing, we make use of different lines and line styles to convey the desired message. These lines differ in (i) thickness and (ii) style. Typical uses of these lines are summarized below. Computer Aided Engineering Drawing
