Summary:The present invention relates to a method for extracting coordinates of a cross-section of an aircraft shape model. The method for extracting coordinates of a cross-section of an aircraft shape model comprises the steps of: loading a shape model of at least a part of an aircraft; extracting lines of intersection between a shape model and a plane in a predetermined direction; determining faulty lines of intersection of the lines of intersection; correcting errors when the errors occur in coordinates of a plurality of contact points; and extracting the coordinates of the plurality of contact points from the lines of intersection. According to the present invention, there is an effect of improving accuracy and efficiency of data extraction by being specialized in an aircraft to classify an area for each shape, determine errors and extract coordinates of an outer surface. 본 발명은, 항공기의 적어도 일부의 형상모델을 로딩하는 단계, 형상모델과 소정방향의 평면간 교선을 추출하는 단계, 교선 중 오류 교선을 판단하는 단계, 복수의 접점의 좌표에 오류가 발생한 경우 보정하는 단계 및 교선으로부터 복수의 접점의 좌표를 추출하는 단계를 포함하는 항공기 형상모델의 단면 절단 좌표 추출 방법에 관한 것이다. 본 발명에 따른 항공기 형상모델의 단면 절단 좌표 추출 방법은 항공기에 특화되어 각 형상별로 영역을 구분하고 오류를 판단하여 외면의 좌표를 추출할 수 있으므로 정확도 및 데이터 추출의 효율 향상의 효과가 있다.
