Abstract: This application discloses a system implementing tools and mechanisms to identify alterations made to a baseline harness design that describes a wire harness, and selectively modify a target harness design based, at least in part, on the alterations made to the baseline harness design. The tools and mechanisms can perform the selective modification of the target harness design through a three-way comparison of the baseline harness design, an altered version of the baseline harness design, and the target harness design. During the three-way comparison, the tools and mechanisms can compare the target harness design to the baseline harness design, and compare the altered version of the baseline harness design to the baseline harness design. The tools and mechanisms can then selectively modify the target harness design based on the alterations made to the baseline harness design and the differences between the target harness design to the baseline harness design.

Abstract: A method of partitioning a model to facilitate printing of the model on a 3D printer includes identifying partition sensitive locations on the model and creating a binary tree with a root note representative of the model. An iterative partitioning process is applied to divide the model into objects by selecting a node of the binary tree without any children nodes, identifying a portion of the model corresponding to the node, and determining candidate cutting planes on the portion of the model based on the partition sensitive locations. During the process, analytic hierarchical processing (AHP) is applied to select an optimal cutting plane from the candidate cutting planes based on partitioning criteria. The optimal cutting plane is used to segment the portion of the model into sub-portions, and two children nodes representative of these sub-portions are created on the node of the binary tree.
