The 3D Harness Bridge transfers electrical data between E3.cable designs and 3D harness design systems. It supports various 3D systems and ProEngineer versions. The bridge uses an XML format to transfer connector, device, wire and cable data from E3.cable to the 3D system for routing, length calculation and collision control. Users must ensure required attributes are set in E3.cable and consult their ProEngineer specialist on prerequisites for importing the XML file.
