The purpose of this guide is to give you the basics of engineering sketching and drawing. We will treat “sketching” and “drawing” as one. “Sketching” generally means freehand drawing. “Drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings.

What are the three stages of engineering drawing?

Usually engineering drawings (of real life objects) are prepared in three stages; sketches, handdrafts and detail drawings. This sequence is not very binding but most workers find it very useful to work in that order. 2.3.1 Sketches

How do engineers communicate their ideas?

One of the best ways to communicate one’s ideas is through some form of picture or drawing. This is especially true for the engineer. The purpose of this guide is to give you the basics of engineering sketching and drawing.

What are the most common applications of technical drawings?

The most common applications of technical drawings can be found in the fields of manufacturing, engineering and construction. For instance, Surveyors, civil engineers, sanitarians use technical drawings to document such works as the layout of a new subdivisions, or the marking of the boundaries for a piece of property.

What is the advantage of isometric drawing in engineering drawing?

Any engineering drawing should show everything: a complete understanding of the object should be possible from the drawing. If the isometric drawing can show all details and all dimensions on one drawing, it is ideal.

What are the requirements for dimensioning a drawing?

Dimensioning 1 Accuracy: correct values must be given. 2 Clearness: dimensions must be placed in appropriate positions. 3 Completeness: nothing must be left out, and nothing duplicated. 4 Readability: the appropriate line quality must be used for legibility.
