Engineering drawing shares some traits with artistic drawing in that both create pictures. But whereas the purpose of artistic drawing is to convey emotion or artistic sensitivity in some way subjective impressionsthe purpose of engineering drawing is to convey information objective facts. Engineering drawing uses an extensive set of conventions to convey information very precisely, with very little ambiguity. Relationship to other technical drawing types[ edit ] The process of producing engineering drawings, and the skill of producing those, is often referred to as technical drawing or drafting draughting although technical drawings are also required for disciplines that would not ordinarily be thought of as parts of engineering such as architecturelandscapingcabinet makingand garment-making.
Lettering having all the alphabets or numerals of uniform thickness is called Gothic Lettering. Single Stroke Vertical Gothic Lettering These are vertical letter having thickness of each line of alphabet or numerals etc.
Same as the single stroke of a pencil. Since Stroke means that the letter is written with one or more stems or curves and each made with single stroke.
Which is quite self explanatory. Roman Lettering The lettering in which all the letters are formed by thick Engineering lettering thin elements is called Roman Lettering.
It may be vertical or inclined or inclined. Free Hand Lettering The writing of alphabets without the use of drawing instruments and in free hand is called Free Hand Lettering.
It may be vertical or Inclined Gothic Lettering. Mechanical lettering does not normally require the use of lettering guidelines.
You will use mechanical lettering principally for title blocks and notes on drawings, marginal data for special maps, briefing charts, display charts, graphs, titles on photographs, signs, and any other time that clear, legible, standardized lettering is required.
The Mechanical Lettering is some times done using special type of device called a Pantograph. The links can move about the hinge. The lowermost link of the parallelogram is fixed to two rigid supports.
One vertical link at one end is connected to a profile tracer which traces the profile of the letter to be drawn and the second vertical link and the other horizontal link are jointly connected to a pencil that draws the exact shape of the profile traced.
The main requirement of lettering on engineering drawing are legibility, uniformity, ease and rapidity in execution. Both upright and inclined letter are suitable for general use. All letters should be capital, except where lower case letters are accepted internationally for abbreviations.
The recommended size of lettering is as under:Aug 30, · 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.
It is not hand written. Also, it may be added here, that Lettering is appropriate and correct. Instant downloads for 28 free engineering fonts.

1 Engineering Lettering Lettering is an essential element in both traditional drawing and CAD drawing. Graphic communication is often not enough to completely describe an object.
Lettered text is often necessary to provide detailed specifications about the 1/5(1). The Roman is the foundation letter. Although there are countless variations of it, there may be said to be three general forms, the early or classic, the renaissance, and the modern.
