polygon orientation in dxf hi i m writing a program to convert dxf files to a database format used by a d graphics program i ve written my program stores the points of a polygon in ccw order i ve used d concepts a little and it seems that the points are stored in the order they are drawn does the dxf format have a way of indicating which order the points are stored in cw or ccw its easy enough to convert but if i don t know which way they are stored i dont know which direction the polygon should be visible from if dxf doesn t handle this can anyone recommend a workaround the best i can think of is to create two polygons for each one in the dxf file one stored cw and the other ccw but that doubles the number of polygons and decreases speed thanks in advance for any help patrice hugo hydra unm edu
