Which of the following is NOT true about planometric drawings?

Planometric drawings are a type of pictorial representation that combines features of both plan views and isometric projections. They allow designers to represent three-dimensional objects in a two-dimensional medium while giving the viewer a clearer understanding of the layout and proportions involved.

The statement about planometric drawings can only being used for architectural designs is not true. While they are commonly employed in architecture, they are versatile in their application and can be utilized in various fields such as industrial design, interior design, and urban planning. This flexibility allows for a broader range of uses beyond strictly architectural contexts.

Additionally, planometric drawings maintain the standard angle projection of features, which means dimensions can be measured directly from the drawing. They also accurately depict three-dimensional objects at set angles, helping convey the object's form and structure, although they do not effectively convey accurate depth perception. The angles typically used in planometric drawings enable viewers to perceive an object's form without providing a true sense of depth.
