Conversion from CATIA to Materialize 3-Matic is not supported yet :(

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.

With Materialise 3-matic, you can clean up rough data for simulation or convert your mesh back to CAD. In addition, it allows you to enhance your design by creating 3D textures, lattice structures and conformal structures, ready for Additive Manufacturing.
