PURPOSE:To obtain a preparation method of a crosssectional view expressing the cross-section of the space possible to build in a correct form as prescribed by architectural laws by integrating slope points on the architectural law in the crosssectional data of the space. CONSTITUTION:A major part consists of a means reading-in contour line data indicating the space possible to build preliminarily stored in a storage device 5, a merge means obtaining the cross point between the read-in contour line data and an arbitrary cross-section and merging the slope points on the architectural laws, and a display means 7 reading-in the merged point train and the crosssectional data which are stored in the storage device 5 as cross-section data by means of the reading means 1 and then displaying them on a visual display device 8. The slope points on the architectural laws are calculated based on the resepctive conditions of environments outside a lot, that is, roads and adjacent lots. Accordingly, a point changing on the slope of the space possible to build can be accurately obtained. The cross pointand the slope points on the architectural laws can be merged by a merge point 3 and re-arranged into the point train indicating the shape of the cross-section. |
