How to convert ArchiCAD (.pln,.pla) 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.

ArchiCAD

ArchiCAD is a popular architectural package developed by Graphisoft Corp.

The recommended way to export 3D data from ArchiCAD and into Okino software is with the special CINEMA 4D Add-On module for the ArchiCAD software. This data can then be imported into Okino software with our dedicated and native CINEMA 4D importer.

Exportable file formats from ArchiCAD are C4D, DXF/DWG, .3ds, Electric Image FACT, U3D, VRML and Wavefront OBJ. Out of these, the U3D and VRML file formats would be acceptable.

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.
