What is the type of engineering drawing?
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component.
What are the 3 major line types that are used for technical drawings?
- Construction Line. This line is used mainly in sketching, which is a freehand drawing technique.
- Visible Object line. This line is used to draw all the edges of the object.
- Hidden Object Line.
- Centre Line (or centreline)
- Extension Line.
- Dimension Line.

What are 3 reasons engineers use drawings?
- Eliminate Questions. A drawing that includes all details and information necessary to successfully manufacture the design (e.g., tolerances, paint specs, electrical specs, packaging specs, etc.)
- Reduce Production Delays.
- Avoid Additional Costs.
