How to convert Navisworks (NWD,NWC,NWF) 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.

Navisworks

Autodesk Navisworks products deliver project review software for 3D coordination, 4D planning, photorealistic visualization, dynamic simulation, and accurate analysis. Create a whole-project model by integrating design and construction information, including complex building information modeling (BIM), Digital Prototyping (DP), and process plant data. With Autodesk Navisworks project review software, you can collaborate, coordinate, and communicate more effectively to reduce problems during design and construction.

Navisworks is a key and core product from which Okino customers often receive and/or coordinate their data files. At Okino we have spent the good part of 2 decades writing our DWF-3D importer specifically to import super-ultra-massive files from Navisworks datasets, such as oil & gas rigs, oil refineries, 3D plants, marine vessils, etc.

Note: you would ideally pre-center the model at the origin and pre-scale the model to be of a "sane size" within Navisworks before exporting the DWF-3D file for Okino software consumption. This will ensure that the model displays properly in your final destination 3D software.

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.
