Introducing a New Method to Convert a 2D Hand-Drawn Perspective to a 3D Digital Model

Abstract

Nowadays, computer-models play an important role in the presentation of architectural designs. Despite the widespread computer advances, many architects still find hand-drawn sketches useful. Some designers use existing rules to draw a specific perspective view of the observer on the paper. In this research, the very first steps of this conversion are studied and introduced as a preface for further investigation into more complicated sketches. The authors try to use the Python programming language to develop an interactive platform in Grasshopper. In this system, a 2D hand-drawn perspective can be imported and converted to a simplified 3D model in Rhinoceros software. By using various algorithms to correct the mistakes in manual design, this method can provide a complete 3D model considering the congruence of the actual drawing.
