  • Reproduction of Drawings:
Original drawings and tracings are normally preserved carefully and copies are used on sites. The blue print copy is developed by immersion in water. Only blue print can provide translucent copy from which further copies can be made.

  • Selection of scales for Drawings:
 It is estimated that drawing to scale 1: 1000 can be read to accuracy of 500 mm and drawing to 1: 400 scale can be read to accuracy of 200mm. If more than one detail drawn on different scale occurs on a sheet, the corresponding scale shall be shown under each relevant detail. Typical method of expressing numerical scales on drawing is 1 cm = 10mm or 1 : 1000 , 1 cm = 2.5 km or 1: 250000. Metric scales for architectural and building drawing is given in code IS: 962 on 12th page.

  • Line Work:
All lines should be dense, clean and black to produce good print. There are different types of lines examples center-lines, hidden lines etc
