After investigating the merits of current CAD techniques for parametric design and three dimensional reconstruction,this paper proposes a new concept of 2D view features based on the global macroscopical structure,topological structure of engineering drawings and the projection rule of 3D features on the three orthegonal view plane.By recognizing and matching the respective 2D view features(2D main features,2D subordinate features) from the three projection views, it can get the corresponding 3D basic features...

After investigating the merits of current CAD techniques for parametric design and three dimensional reconstruction,this paper proposes a new concept of 2D view features based on the global macroscopical structure,topological structure of engineering drawings and the projection rule of 3D features on the three orthegonal view plane.By recognizing and matching the respective 2D view features(2D main features,2D subordinate features) from the three projection views, it can get the corresponding 3D basic features and builds the feature chain,so a 3D feature base model is established. With the relation between 2D view features and 3D basic features,an integrated algorithm for multi view parametric driven by dimensions, 3D parametric and 3D reconstruction is developed. The method based on 2D view features is simple and practical.

Contour matching is one of the important problems concerned in graph and image processing field. Aiming at implementing the planar contour recognizing and matching in the CAD modeling based on the slice images, some fruitful research works are presented in this paper. Firstly, a contour forest is established to reduce the searching range in the contour matching and to recognize the in-out features of contours. An ellipse-fitting algorithm is then applied to describe the completed shape and locating information for the series of discrete contour points and to realize primarily the slice contour matching. Finally, a weighted rotating-branching algorithm has been proposed to resolve the branching problem. The efficiency of this algorithm has been verified by several typical examples and some satisfying results have been obtained.
