Q3. Isometric to orthogonal representation
Ans. 
Isometric and orthogonal representations are two different ways to depict objects in engineering and design.
• Isometric representation shows objects in a 3D perspective with all three dimensions equally foreshortened.

• Orthogonal representation shows objects in a 2D format with each dimension shown separately and to scale.

• Isometric drawings are often used in technical drawings to show a 3D view of an object, while orthogon...read more
