What are Engineering Sketches and who uses them?

Engineering Sketches also known as technical drawings are diagrams created to covey graphically the ideas and information necessary for the construction or analysis of structures, systems, machines etc.

The basis of most engineering Sketches is orthographic representation (projection).  Objects are depicted by top, front, side, auxiliary, or oblique views, or combination of some or all of these views.

To make the drawings easier to understand, people use standard symbols, units of measurement, notation systems, visual styles and page layout to communicate ideas. Together these ideas create a visual technical language that is easy to understand for people in the industry.

Engineering Sketches often include lines symbols, brief notes, sectional views etc. They may be in the form of carefully planned and engineered drawings or free hand pencil sketches.

When drawings have complicated, details which cannot be communicated from a single view, additional or several different sectional drawings are created to communicate the idea.  Sometimes imaginary cut views are produced to visualize what the inner material or joint would look like.  This process is also know as crosshatch.

Besides communicating the shape of an object all drawings will have to list the true dimension or scaled dimensions of the object.  This is to help fabricators or assemblers to assemble to the project.  Angled lines also called leaders are used to highlight object(s) dimension for quick reference. More detailed information is normally delivered in Spec (specification) books.

Engineering sketches of different types are used in different manufacturing fields for various purposes.  One is the layout drawing, in which the outline of building, structure, machine etc. is outlined as to how many parts are comprised together to create the project.  Project estimators will spend hours reading these drawings from different angles to estimate cost, create a building plan and also create the safest procedure to tackle the project.  A second type of drawing is assembly (also know as preliminary drawing) which would explain the way parts are supposed to be positioned for assembly.  They would also clarify the clearance and fastening method used to secure the parts together.  The third type of drawing is a working drawing.  This drawing would include detailed drawings of all parts and general assembly drawings.  The fourth type of drawing is the schematic drawings which would use standard symbols to indicate the direction of flow in pipes and electrical wiring.
