What is the main difference between an isometric drawing and a sketch?

• An isometric drawing is freehand, while a sketch is precise.

• An isometric drawing shows equal dimensions of three sides, while a sketch is freehand and conceptual.

• A sketch shows views from different angles, while an isometric drawing is 2-D.

• A sketch requires dimensions, while an isometric drawing does not.

Why are orthographic projections important in engineering?

• They provide a pseudo-3D perspective.

• They are used for artistic designs.

• They allow engineers to view objects from multiple angles to manufacture them accurately.

• They are freehand drawings used for brainstorming.
