A method is provided for automatic hose and harness routing. The method may include obtaining a solid model of a structural design of a structure assembly and deriving a mathematical representation of the solid model. The method may also include selecting at least a pair of connection points, including a start point and an end point and determining a desired path between the start point and the end point. Further, the method may include performing a validity check on the desired path to decide whether the desired path is valid and presenting the desired path.
