The three fundamental types of technical drawings for the architectural design process are the elevation views, floorplans and the section views.
The elevation view is a representation of elements across a vertical section plane allowing you to observe the shapes and sizes of facades, while a floorplan view, shows the internal construction layout from a bird's eye-view cross-sectioned by a horizontal plane, the section view is an orthogonal projection of a building sectioned by a vertical plane.
For a complete description of an architectural project, further types of technical drawings may also be necessary, such as a territorial context map, an extract from the current implementation plan, the general area plan, axonometric and cutaway drawings, perspective views and photorealistic renderings.
