From 2D Orthographic Views to 3D Pseudo-Wireframe: An Automatic Procedure

Free registration required

Executive Summary

Three-dimensional CAD models are usually used by designers because of their multiple uses (visualization, simulation and machining). However, nowadays, multi orthographic view engineering drawings are still widely used. Accordingly, a conversion tool for obtaining 3D CAD models from 2D drawings (known as the "Reconstruction problem") is a very useful approach in a broad range of applications. The significant interest for the reconstruction problem is witnessed by the large number of works presented in the last three decades. The main object of the paper, by integrating different approaches suggested by a number of authors and rearranging them into an orderly, unambiguous and automatic procedure, is to provide a tool to help researchers and practitioners who want to deal with the reconstruction problem.
