Computer-Aided Design Specialist II (SEMATS)

Provides technical support to the SEEK EAGLE Modeling Analysis and Tools Support (SEMATS 3) contract at Eglin AFB, FL. Conducts computer aided design (CAD) development efforts that provide three-dimensional (3-D) compatibility engineering modeling and simulation capability to check store fit on aircraft as well as supporting the Computerized Physical Fit (CPF) Team to produce 3-D solid models for the DoW. Use of Siemens NX to create and manipulate 3-D models of DoW aircraft and stores. This includes digital modeling of aircraft, suspension equipment, and stores, as well as the application of a kinematic program that simulates movement of control surfaces, landing gear, etc., to predict physical fit under changing aircraft and store loading configurations.

Essential Job Functions :

Responsible for creation, modification, and manipulation of 3D models from drawings, scanned data from 3-D scanners, manufacturer’s converted CAD data and faceted body data depicting the external surfaces of the aircraft or store.

Manages the CAD Data Library (CDL) of 3D models for the Air Force SEEK EAGLE office (AFSEO) as well as  maintaining the Master Model Library (MML) that documents the originating data used to construct the AFSEO 3D model libraries. Management of these data libraries will make up the majority of the workday.

Interfaces with customer representatives at all levels to understand CPF modeling requirements and transforms solid bodies into desired 3-D model formats and resolutions.

Supports other engineering disciplines within the SEEK EAGLE Office to include CFD, Stress and other teams with derivatives of the CPF models for analysis purposes.

Manually generates additional 3-D solid and surface data to approximate the highly detailed CPF CAD models when necessary for external customers.

Assists in the measurements and 3-D scans of aircraft, weapons, and suspension equipment for 3-D model verification and validation as well as reverse engineering initiatives. Some travel may be necessary to capture the 3-D data needed for model creation.

Imports and translates CAD file formats and exports 3-D models in IGES, STEP, DXF / DWG or VRML as needed.

Applies process improvement methods, tools, and techniques to achieve higher levels of CPF system quality and productivity.

Required Skills :

Due to the sensitivity of customer related requirements, U.S. Citizenship is required.

Associate’s Degree required, with a Bachelor's Degree desired, in Computer Science, Software Engineering, Physics, Mathematics, or other related field (5 years of related experience with Associates Degree or 3 years related experience with a Bachelor’s Degree).

Minimum of 3 years of general experience in computer-based modeling and simulation and / or use of 3D CAD modeling applications with engineering drawings, blueprints, and / or actual physical items.

Siemens NX CAD experience is desired and will be the primary CAD application used on a daily basis. Utilization of reverse engineering tools and scanners (Design X, Polyworks Inspector, etc.) is a plus.

Works well in a team environment, sharing modeling techniques and willing to train and pass along skills and knowledge to other modelers in the team, to improve on their skills.

Familiarity with aircraft, stores (weapons, fuel tanks, pods, missiles, etc.), and suspension equipment is a plus.

General machine shop and aircraft construction knowledge is a plus.

Other CAD software knowledge such as CATIA, PRO-E, Solidworks is a plus.
