CATIA Generative Aerospace Sheet metal Design is a product dedicated to the definition of sheet metal parts used in the aerospace industry (hydro-pressed or break-formed). It enables the capture of company knowledge, including design, and manufacturing constraints.Product is based on Feature Modeling techniques, using a pre-defined set of Features used for sheet metal parts designed in the aerospace industry.Based on both specification-driven and generative approaches, this product will allow typical hydro-formed aerospace parts to be easily specified, the system taking care of creating both 3D and flattened part geometry. Where such parts are designed or modified with basic modeling tools within hours or days, this product allows same result to be achieved in minutes.
CATIA Generative Aerospace Sheet metal Design provides an interactive function to design sheet metal parts in a very intuitive way, taking manufacturing constraints into accounts. It provides the flatpattern of the sheet metal part, and allows easy incremental design (from preliminary to detailled stages) and modification both in 3D and flattened conditions.Whenever initial specifications are changed (e.g. the aircraft skin on which a frame has been designed is modified), this product will allow new part to be automatically rebuild, based on new specifications.

Product Key Customer Benefits
Specification-Based Design… Using feature-based techniques and technological attributes, aerospace designers can quickly create sheet metal parts (hydro-pressed or break-formed) with Generative Aerospace Sheet metal Design. The intelligent tools of this system enable designers to generate and modify their models, such as frames, within minutes instead of hours or days.Automated Modification capabilities… Designers can effect modifications through changes to defined features and technological attributes or direct geometry manipulation. As designers make changes in specifications, the system automatically updates the geometry.
Flexible Solution… Generative Aerospace Sheet metal Design allows designers to switch from one representation — whether solids or surfaces — to another whenever they want. Users can create and modify their design as a 3D formed part or a 2D flat pattern. Due to the design approach’s flexibility, users can initially define the part through major functional characteristics that comply with the part’s general dimensions. Later, the designers can add holes and cutouts for access as well as place components and fasteners.
2D and 3D Capabilities… Generative Aerospace Sheet metal Design can automatically compute a 3D formed part as well as 2D flattened part geometry from the technical specifications. With user-defined neutral fiber data, the system computes bend allowance when flattening the design. Associativity between the flattened and formed part ensures accuracy of design details and helps designers ensure manufacturability. Associativity is also maintained with the drawings. This integration of aerospace sheet metal parts into the drafting environment avoids duplicate part definition, thereby increasing data integrity.
Dedicated Aerospace Interface… With Generative Aerospace Sheet metal Design, designers work with familiar aerospace features enabling them to concentrate on their design project. Some of these aerospace-specific design features include:
• Flange (curved, double curved or planar)
• Flange cutout
• Flanged hole
• Flanged slot
• User Flange
• Stiffening bead
• Stiffening Rib
• Corner relief
• Planar Flange
• Tear Drop
Captured Company Expertise… Users are able to create files with defined corporate standards for such features as holes, stiffening beads or lightening holes. As many files as necessary can be created for different materials, machines, or projects. This enables CATIA users to take advantage of the technical expertise in defining their model specifications. Integration of the Company standards improves design quality and reliability.
