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.

ArcGIS

ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri.

Preferred methods to convert from Okino software and into into ArcGIS: DWF-3D, DXF/DWG, Collada, Microstation DGN.

Preferred methods to convert from ArcGIS and into Okino software: ESRI ShapeFiles, Adobe U3D files, DWF-3D, VRML, Microstation DGN, Collada, 3ds (not recommended).

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.
