Abstract :
A method is presented for identifying the views in an engineering drawing along with their associated view points in preparation for 3D interpretation of the object shape. A formal procedure is developed for constructing a set of view-based coordinate systems that act as intermediate 2.5D coordinates to relate the 2D drawing-based coordinates to the 3D object-based coordinates. The method can accommodate auxiliary views in addition to the standard orthogonal set, and the number of views and their layout in the drawing need not be known a priori. Moderate errors in line placement and view alignment can also be accommodated
