INTRODUCTION Lettering is an impotent part of engineering drawing. It gives information regarding size, and instructions, in the form of notes and dimension. On a drawing, whole of the written information is always in the form of lettering. Also, it may be added here, that Lettering is appropriate and correct Pen Sizes and Line Types. The ISO defines a set of standard metric line widths for drafting. Like the ISO A and B series sheet sizes, the pen sizes increase by a factor of 2. This allows additions and corrections to be made on the enlargements or reductions of.

It is more common in engineering drawings than in architectural drawings. Engineering Drawing Practices These drawing types are not used for items made from raw or bulk materials, items purchased in bulk lengths, or such semiprocessed items as blank panels, castings, electronic equipment drawers, etc. (For such items, use detail or detail assembly drawings. Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering.
