A Genetic Algorithm based Optimization Method in 3D Solid Reconstruction from 2D Multi-View Engineering Drawings
There are mainly two categories for a 3D reconstruction from 2D drawings: B-Rep and CSG that both these methods have serious weaknesses despite being useful. B-Rep method which has been older and have wider function range is problematic because of high volume of calculations and vagueness in answers and CSG method has problem in terms of very limited range of volumes and drawings that it can an...
متن کاملSolid model reconstruction from engineering paper drawings using Genetic Algorithms
The wide applications of CAD/CAM technologies have promoted the development and application of many advanced technologies, such as digital manufacturing, rapid prototyping, enterprise resources planning, computer integrated manufacturing, concurrent engineering, virtual reality, and mass customization. These advanced technologies all need to be supported by three-dimensional (3D) solid models o...
متن کاملReconstruction of curved solids from engineering drawings
This paper presents a new approach for reconstructing solids with planar, quadric and toroidal surfaces from three-view engineering drawings. By applying geometric theory to 3-D reconstruction, our method is able to remove restrictions placed on the axes of curved surfaces by existing methods. The main feature of our algorithm is that it combines the geometric properties of conics with af®ne pr...
متن کاملNew method of 3D reconstruction from mechanical engineering drawings based on engineering semantics understanding
3D reconstruction from mechanical engineering drawings is a method of automatic generating 3D solid models. For the purpose of enhancing the practicability of the technique of 3D reconstruction, this paper presents a new reconstruction method based on engineering semantics understanding. Its principle is similar to the method of figuration analysis used by experienced engineers. The characteris...
متن کاملDimension Recognition and Geometry Reconstruction in Vectorization of Engineering Drawings
This paper presents a novel approach for recognizing and interpreting dimensions in engineering drawings. It starts by detecting potential dimension frames, each comprising only the line and text components of a dimension, then verifies them by detecting the dimension symbols. By removing the prerequisite of symbol recognition from detection of dimension sets, our method is capable of handling ...
