Isometric in 3D modeling illustration is an axonometric projection that represents 3D objects on a 2D plane with equal scale along the x, y, and z axes, eliminating perspective distortion.
It uses consistent 120° angles between axes to keep objects proportional and measurable—perfect for technical diagrams, game assets, or UI mockups where clarity and consistency matter more than realistic depth.
For stylized art or technical drawings, isometric simplifies spatial representation while retaining logical proportions, skipping the need for complex perspective setup.
