PROBLEM TO BE SOLVED: To perform drawing while automatically changing a direction of a part in drawing the part having a longitudinal direction such as a duct or in changing its diameter. SOLUTION: In an information processing device for arranging a facility route by connecting each part and creating a facility drawing, when creating a facility drawing or changing the diameter of a part, a direction of a branched part is determined by changing the direction or the part such that the part with a larger diameter is connected to a section of the branched part where the diameter is largest, by comparing diameters of the parts to connect. When both sides of a main pipe is of the same diameter in the case where a main pipe is branched into branched pipes, and the main pipe is branched to straight pipe by simple attachment, the connection of both sides of the main pipe is tracked for searching the change in diameters and the way of connection, and whether the searched pipe is a main pipe or a branch pipe is determined so that the direction of the simple attachment is determined.
