What are engineering standards?
It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes and practices. The documents prepared by a professional group or committee which are believed to be good and proper engineering practices and which contain mandatory requirement.
Why are standards important in engineering drawings?
Standards provide rules for their specification and interpretation. Standardization also aids internationalization, because people from different countries who speak different languages can read the same engineering drawing, and interpret it the same way. One major set of engineering drawing standards is ASME Y14.
How is a half scale drawing written?
Half scale is 1:2. It is helpful to think of this as one unit on the drawing equals two units on the object. A small object can be enlarged on the paper and drawn in 2:1 scale. … For example, 1:50 scale equals one-fiftieth (1/50) full size–or 1 millimeter on the drawing equals 50 millimeters in reality.

How do engineering sketches and drawings convey design?
The purpose of design/engineering drawing is to communicate your ideas to other people in the simplest form possible. Your drawings don’t need to be elaborate or fancy. They just need to get your ideas across to others through simple shapes and symbols. Start your drawing training by practicing the simplest of shapes.
What scale are elevations drawn at?
Generally, interior elevations are drawn to the same scale as the floor plan(s). If the wall plane and other items are fairly simple, then a scale of 1/4″ = 1′-0″ (1:50 metric) is acceptable. This is especially applicable in large public spaces.
