1. How will you differentiate the English system from Metric system?
2. Why it is necessary to learn proper dimensioning in constructing orthographic drawings?
1. The Metric System of Measurement is easier to use than the English System of Measurement since its conversion factors would consistently be in the decimal system, unlike the English System of Measurement where units of lengths have different conversion factors.
2. Since an orthographic drawing is a clear, detailed way to represent the image of an object, it requires proper dimensioning to provide a clear and complete description of an object.
