Main concepts Key drivers
Another crucial aspect is that transfer between CAD 3D shape and CAE analysis information may be bi-directional, enabling the feedback of information in the iterative design/analysis environment.
Summary STEP AP209 = CAD : Nominal CAD Geometry One can use AP209 with any one or more of these pieces, but the real power lies with the assemblage of all these parts.
High Level AP209 ed2 Composition Due to the new modular architecture, STEP AP209 ed2 shares all modules with STEP AP242 thus ensuring perfect integration. The figure here after presents the hierarchy of STEP AP209 ed2 modules:
