orthographic
One disadvantage of using isometric drawings is that they can sometimes distort the true dimensions of an object, making it challenging to accurately represent the size and proportions of the object. Additionally, isometric drawings can be more complex to create compared to other types of technical drawings, such as orthographic projections. Lastly, isometric drawings may not always provide all the necessary information needed for precise engineering or design purposes, as they do not show all sides and angles of an object simultaneously.
Orthographic grid paper is grid paper that allows for isometric drawings. This allows for 3 dimensional drawings, and is common for drawing construction diagrams, as-builts and such. For example, you could use this to account length, width, and elevation.
1) Some training is necessary before you can draw or read a drawing. 2) Sometimes it's easier to draw the object in perspective view (pictorial view), especially for clients who have difficulties interpreting orthographic drawings.
Drawings in engineering and design can be categorized into several types, including isometric, orthographic, assembly, circuit, block, and schematic diagrams. Isometric drawings provide a 3D representation of objects, while orthographic projections show multiple 2D views (top, front, side) of an object from different angles, typically utilizing first or third-angle projection methods. Assembly diagrams illustrate how individual parts fit together, whereas circuit diagrams depict electrical connections and paths. Block diagrams simplify complex systems into basic components, and schematic diagrams represent the functional relationships within electrical systems, making it easier to understand and analyze designs.

The different types of pictorial drawing include isometric, oblique, and perspective drawings. Isometric drawings show all three dimensions of an object in a single view with lines parallel to the three major axes. Oblique drawings represent objects in 3D by showing one face in true scale and the other two faces at an angle. Perspective drawings create the illusion of depth and distance by using vanishing points and converging lines.
At 45° angle.
Isometric, Orthographic and Perspective, but perspective is not required to depict an object.
because 2nd and 4th angle projection overlap each other
Amagine looking at a cube from an angle. Now to make that orthographic amagine looking at it straight. A cube would just be a square.
It's fun if you're into making models and doing technical drawings such as orthographic drawings for example. Models and drawings are a major part of the architecture course. There's alot of different practicals and projects you'll be doing before actually designing a building !
