Mechanical CAD in the Engineering division consists of a suite of applications/processes that enable a workflow encompassing the entire design methodology.  The process runs from the initial requirements given to our engineers and designers to the final product/assembly installed in our instruments.  This includes requirements management, design, analysis, and visualization through to the documentation required for fabrication and procurement.  Designs are modeled in various 3D CAD applications and the data generated from these tools are collected and managed in controlled repositories called Product Lifecycle Management systems.  Document control is the final arbiter of released documentation and is utilized in the procurement and manufacturing of our designs.
