A thumbnail sketch is a small, quick, and rough drawing used to explore ideas and compositions for a larger, more detailed artwork. It's a planning tool that helps artists visualize and experiment with different options before committing to a final piece

An isometric sketch is a type of technical drawing that depicts a three-dimensional object on a two-dimensional surface. It's used to represent all three dimensions of an object in a way that preserves their relative sizes and angles, unlike perspective drawings where foreshortening occurs. In an isometric sketch, horizontal edges are drawn at a 30-degree angle, vertical edges are drawn vertically, and parallel lines remain parallel

In engineering and design, a perspective sketch is a method of representing a 3D object on a 2D surface, creating the illusion of depth and distance. It achieves this by using vanishing points, a horizon line, and foreshortening. Perspective sketches are valuable for visualizing design concepts, communicating ideas to clients, and creating realistic illustrations for engineering documentation

In engineering, an orthographic sketch (also known as an orthographic drawing or orthographic projection) is a two-dimensional representation of a three-dimensional object, showing multiple views of the object from different angles. These views are projected onto perpendicular planes, creating a series of flat, two-dimensional representations that accurately convey the object's shape, size, and dimensions
