The Mechanical Designer will help ensure that CAD models, drawings, bills of material, configuration records, engineering changes, and associated technical data are structured, traceable, and maintained in a manner that supports lifecycle visibility from concept development through fabrication, installation, test, sustainment, and future configuration reuse. 3D CAD Modeling and Mechanical Design Support Develop fully parametric 3D solid models, assemblies, subassemblies, and component models in Autodesk Inventor based on sketches, redlines, field measurements, legacy drawings, vendor data, and design-engineer direction.
