Orthographic projection is primarily used for what purpose?

Orthographic projection is primarily used for creating architectural plan and elevation drawings. This method allows for the representation of three-dimensional objects in two dimensions by projecting the object’s dimensions onto a flat surface. It utilizes multiple views, typically the front, top, and side, providing a comprehensive understanding of the object's size and shape without distortion.

In architectural contexts, orthographic projection is crucial because it helps architects and engineers communicate design intent accurately. By using these drawings, details such as dimensions, materials, and structural relationships can be clearly displayed, making it easier for builders and contractors to interpret and construct the designs accurately.

This method is distinct from merely creating three-dimensional models, which involves a different approach and is more focused on visualizing the object in three-dimensional space rather than providing detailed specifications. The option regarding viewing objects from one perspective does not encompass the full utility of orthographic projection, as it typically requires multiple views for complete clarity. Similarly, while ortho projections can inform fire hazard assessments, the primary application is in the realm of architectural drawings rather than evaluation tasks.
