Landscape architecture drawings serve to communicate design concepts and translate how natural elements will integrate into a site. Drawings start with site analysis and progress through conceptual sketches, orthographic projections, perspectives, and 3D models. Techniques include tracing paper, erasers, pencils, and gridding to accurately convey site measurements, angles, and perspectives. As the field has evolved with new technologies, drawings now collaborate different mediums to reflect the intended nature and atmosphere of a site over time.
