CPACS 3.5.1

CPACS 3.5.1 feature list

• Refinement of the systems definition introduced in CPACS 3.5
  • update the geometry concept for predefined systemElements
  • add multiSegmentShapes and external CAD references
  • allow combined shapes in predefined systemElements with individual transformations
  • remove aircraft-level scaling for instantiated generic systems to avoid ambiguous semantics for mass, center of gravity, and inertia properties
• Refinement of decks to better align with systems
  • harmonize the handling of deckElements and systemElements
  • replace the previous boundingBox-based approach by the same general geometry building blocks used for systems
  • replace the former 2D-only deck instantiation concept by a consistent 3D transformation
  • allow cargo containers to be handled as regular deck elements
• Refinement of the fuelTanks definition introduced in CPACS 3.5
  • move vessel-based tanks to vehicles/aircraft/model/fuelTanks
  • replace XML nesting below fuselage by placement via parentUID, allowing tanks to be attached to fuselages, wings, nacelles, and other geometry parents
  • rework the internal tank definition around vessels
  • improve support for structural definitions on vessel level
• update and consolidate example files for systems and fuel tank use cases
• build improvements
  • add tool-specific documentation support
  • update build instructions

Note: The refinements of systems, decks, and fuelTanks are not backward
compatible with CPACS 3.5. Existing datasets using these nodes need to be adapted.
