Conversion from CATIA to T-FLEX 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.

T-FLEX is a Parasolid-based parametric CAD software application for 3D solid modeling and 2D design and drafting, made by Russian software company Top Systems. T-FLEX CAD is developed for Microsoft Windows XP, Vista and is localized into many languages.

T-FLEX CAD is a design solution which was created for mechanical engineering. It provides drafting, modeling and assembly tools that allow engineers to develop various products, from single parts to assemblies.

T-FLEX CAD supports a wide range of operations: drawings, assembly drawings, solids, surfaces, parts, parts with multiple solid bodies, assembly models, sheet metal, bill of materials, etc.

T-FLEX CAD provides parametric, adaptive and associative technology aimed at family-of-parts manufacturers or other design situations that use similar geometry but require many different sizes or permutations. Besides parametric 3D modeling T-FLEX CAD supports parametric 2D drawings creation from scratch. Parametric 2D assemblies can be created as well by inserting parametric 2D components.
