The main difference between orthographic and isometric projection lies in how they represent 3D objects in 2D space:
Orthographic Projection:
Shows the object from specific, flat views (e.g., front, top, or side).
There is no 3D effect; each view is drawn separately.
Dimensions are accurate and undistorted, making it ideal for technical drawings.
Isometric Projection:
Shows the object in a single view where three sides are visible at once.
Gives a 3D appearance by angling the object so the axes are equally spaced (typically at 120°).
Dimensions are slightly distorted but still proportional, making it useful for visualizing designs.
In short, orthographic projection is for precision and technical details, while isometric projection is for a 3D-like visualization.
