Conversion from Intergraph Smart 3D to CATIA is not supported yet :(

Intergraph Smart 3D, the most advanced plant design software offered in two decades, is Intergraph’s next generation, data-centric, rule-driven solution for streamlining engineering design processes while preserving existing data and making it more usable/re-usable. A fundamental component of Intergraph’s SmartPlant Enterprise, Smart 3D is a complementary, full-suite solution that provides all the capabilities needed to design a plant, and then keep it as built throughout its life cycle.

CATIA is a multi-platform software kit for CAD/CAM/CAE, PLM and 3D, created by the French company Dassault Systèmes.

Commonly referred to as a 3D PLM software suite, CATIA supports all stages of product development, including conceptualization, design, engineering and manufacturing. CATIA facilitates collaborative engineering across disciplines around its 3DEXPERIENCE platform, including surfacing & shape design, electrical, fluid and electronic systems design, mechanical engineering and systems engineering. CATIA facilitates the design of electronic, electrical, and distributed systems such as fluid and HVAC systems, all the way to the production of documentation for manufacturing.
