METHOD FOR DISPLAYING REDUNDANT NODES ON A TWO DIMENSIONAL PLANE OF A NODE SCHEMATIC DRAWING

摘要

The present invention relates to a method for displaying a plurality of overlap nodes displayed on the same position when 3D cableway information is displayed on a 2D node schematic drawing in a 3D cableway modeling environment. The present invention comprises a first step for analyzing 3D coordinates (x, y, z) of all nodes (20); a second step for displaying the all nodes on virtual 2D planes (x, y); a third step for memorizing nodes which are displayed in the position overlapped on the virtual 2D planes in a memory as an overlap node (22); and a fourth step for confirming overlap node information memorized in the memory, finishing the processing in case of not existing in the memorized overlap node, and moving to an overlap node processing step in case of existing in the memorized overlap node. The overlap node processing step comprises a step for determining a reference node (24) among the nodes included in the overlap nodes; a step for offsetting the remaining nodes excluding the reference node and displaying the same; and a step for deleting the overlap node in which the offset processing is completed in the memory and returning to the fourth step. The step for determining the reference node (24) comprises a step for arranging Z coordinates of the nodes; a step for analyzing the number of nodes included on the X and Y planes comprising the Z coordinates among the all nodes (20); and a step for determining the node comprising the Z coordinates as the reference node (24).
