1. Machines and Engine Components: Orthographic Projections and Isometric Views Orthographic Projections: This refers to a method of representing three-dimensional objects in two dimensions. In engineering drawings, orthographic projection involves creating views (top, front, and side) of machine components, allowing each part of the machine to be clearly detailed from different angles. Isometric Views: An isometric view is a way of representing a 3D object in two dimensions, where the object is shown at an angle, and the axes are typically spaced at 120° from each other. This is particularly useful for piping and ducting, as it helps visualize how systems like these are arranged spatially without distorting the proportions. Standard Practices: This refers to adhering to common rules or conventions in drafting (such as line thicknesses, dimensioning, tolerances) so that drawings are easily understood by others in the industry. 2.
