Classification and elimination of overlapped entities in DXF files

(in lingua inglese)

The present research is a step toward enhancing file manipulation in CAD/CAM systems. It focuses on 2D drawings in DXF file format. The developed algorithms reduce the file size through elimination of overlapping entities; POINT, LINE, CIRCLE and ARC. Moreover, it unifies the entities format in predefined ones and reduces the number of used layers. The algorithms are explained in details. A computer program is established to apply the developed algorithms. The computer program was tested using specially prepared files for every entity type.
