How to convert CATIA (.catpart,.catproduct) to STK (Satellite Tool Kit, Systems Tool Kit, MDL)?


PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

     

CATIA

CATIA, developed by Dassault Systèmes, is an integrated suite of CAD, CAE and CAM applications for digital product definition and simulation. CATIA is primarily used by the automotive and aerospace industries for automobile and aircraft product and tooling design.

The key file extensions used with CATIA v5 software are ".catpart" for the part and geometry files, and ".catproduct" for the assembly files.

Conversions from CATIA can best be done either via Okino's native CATIA v5 importer (which is based on the real and actual CATIA v5 runtime system licensed from Dassault Systèmes), or equally well via STEP AP214 files.

     

STK

Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. 'MDL' is the native file format of the STK software.

Okino has been a fundamental and long term 3D file conversion partner to AGI since 1998. Originally the conversions from Okino software and into STK were done by exporting LightWave .lwo files, then COLLADA .dae files as of 2008, and in now recent years glTF files.
