Technical drawing departs from other graphic illustration skills by foregoing illustrative devices, such as vanishing points, that depict objects from a single point in space. This creates an inexact, estimate-based perspective, where neither dimensions, angles, nor distances can be trusted exactly as depicted. Most structural drawing, engineering design, and architecture drawing products thus depend on isometric drawing and orthographic projection. This is a perspective that aims to capture every measurable component of an object or space. It aims to eliminate misinterpretation issues that would otherwise occur with dimensional perspectives. To do so, it requires the technical artist to imagine the object(s) being designed from within a geometrical shape, most often a cube. Then they deconstruct it into all views. Sometimes, it only requires one of those views (e.g., a floor plan) to complete the necessary work.
