PROBLEM TO BE SOLVED: To provide a method for creating a piping route capable of efficiently routing piping or wiring, an apparatus for creating linear patterns, and the like. SOLUTION: A rectangular parallelepiped containing the starting point R1 and the end point S of a piping route as its apexes is virtually formed and any interference between each side of the rectangular parallelepiped and equipment is detected. If the presence of an interfering object on any side of the rectangular parallelepiped containing the starting point R1 and the end point S as its apexes is detected and if no route extending from the starting point R1 to the end point S without the presence of any interfering object is found, the starting point R1 is shifted to a starting point R2 and so on, so as to virtually form other rectangular parallelepipeds in the same way and detect interference with the equipment. Moreover, sizes by which the starting points R1, R2 and so on are shifted are basically equal to the standard sizes L1, L2 of a straight pipe and the standard sizes L11 and so on of an elbow pipe. When the starting points R1, R2 and so on are shifted in sequence, the direction in which the piping route was extended during the previous process is given the highest priority.
