Identification of Sections from Engineering Drawings Based on Evidence Theory

Abstract : View identi¯cation is the basal process for solid reconstruc- tion from engineering drawings. A new method is presented to label various views from a section-involved drawing and identify geometric planes through the object at which the sections are to be located. In the approach, a graph repre- sentation is developed for describing multiple relationships among various views in the 2D drawing space, and a rea- soning technique based on evidence theory is implemented to validate view relations that are used to fold views and sections in the 3D object space. This is the ¯rst automated approach which can handle multiple sections in diverse ar- rangements, especially accommodating the aligned section for the ¯rst time. Experimental results are given to show that the proposed solution makes a breakthrough in the ¯eld and builds a promising basis for further expansibility, although it is not a complete one.
