A Review of 3D Reconstruction Techniques from 2D Orthographic Line Drawings

3D reconstruction of objects form orthographic projections of engineering drawing has been very crucial research area since decades. In this paper, we have critically reviewed the latest approaches dealing with single view and multi view. Different approaches have been discussed with respect to bottom-up and top-down reconstruction. Many other parameters such as type of drawing, shape of object, x-sectional view, user interaction, dead end holes and hidden lines have also been compared amongst these approaches.
