Our computer-aided design (CAD) group uses various software tools and over 100 trained CAD users to provide seamless integration with the design agent’s CAD data, thus reducing cycle time, eliminating errors, and ensuring delivery of a compliant product. DRS has the capability to accept and use electronic design data from multiple customers in multiple formats. To control this data, DRS maintains a part model database that facilitates rapid response to support design changes. CAD Software tools include: CREO( ProEngineer), Unigraphics, SolidWorks, AutoCAD Inventor, Mentor, and CircuitCAM to handle a wide variety of customer and supplier document / model formats.

DRS is experienced in the use of data exchange formats such as Standard for the Exchange of Product model data (STEP) and Initial Graphics Exchange Specification (IGS) files. Data Exchange formats have advanced to be nearly indistinguishable from the native CAD program file.

CAD models effectively communicate the design details to the manufacturing team early in the design. Communication allows Design for Manufacturing and Assembly (DFM/A) brainstorming with the Production Team concurrent with design efforts. DRS designers use analysis tools such as Finite Element Analysis (FEA) and Thermal/Computational Fluid Dynamics (CFD) (Ansys and ICEpak software) to expose potential flaws in the design concept prior to procuring material for production. Virtual assembly can be done prior to availability of hardware which uncovers design errors, tool access issues and interferences.

DRS CAD specialists routinely develop and update engineering and assembly drawings including System Elevations, Schematics, Wiring Diagrams, 3-D Models, Labeling Details, block diagrams, Installation Control Drawings, and Installation Requirements Drawing (IRD) packages in accordance with Enclosure (3) to SPAWARINST 4720.5.

We offer flexible CAD support for long-term projects, as well as short-term situations when your organization needs additional temporary support.
