A method and system are described that allow conversion of a three-dimensional representation of a wire harness to a two-dimensional representation. In one aspect, an optimal viewing angle of the three-dimensional representation is automatically computed such that overlap of nodes and/or branches is minimized. Using the optimal viewing angle, the three-dimensional representation is converted to two dimensions.In another aspect, the optimal viewing angle is obtained through rotation of the three-dimensional data. One technique for performing such a rotation is by determining a plane associated with the viewing angle, the plane being such that the average distance from nodes in the wire harness to the plane is a minimum.
