How to convert Autodesk Inventor (.iam,.ipt) to OrcaFlex (.yml,sim,.owr)?

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.


Autodesk Inventor

Autodesk Inventor is Autodesk's main MCAD "BREP solids" modelling software program which has competed with its rivals of SolidWorks, ProE/Creo, Solid Edge, Unigraphics NX (and partly) CATIA v4/v5 since its original release in 1999.

The file formats of key importance would be ".ipt" which contains the geometry of each part/object in the scene, and, ".iam" files which contain the scene assembly information.

Conversion from Autodesk Inventor into Okino software is handled by these 3 ideal methods:

  • Via DWF-3D files exported from Inventor. This is the most ideal and "least mentally taxing" conversion method. It also supports material and texture map conversion.
  • Via native import of the .iam or .ipt files,
  • Via STEP AP214 or IGES 'BREP solids' files.



OrcaFlex is a leading package for the dynamic analysis of offshore marine systems. OrcaFlex is renowned for its breadth of technical capability and user friendliness. OrcaFlex is used by offshore engineering business, with others in seismic, defence, ocean engineering, oceanographic research, aquaculture and related fields.

Converting data from Okino's conversion software into OrcaFlex can best be achieved using the DirectX file format, using Okino's bullet-proof DirectX export conversion system. The Orcina WEB site recommends that the exported models not be too large. If you are converting CAD models then you can set the mesh density on each Okino CAD importer. You can also use Okino's CAD-biased polygon reduction system to reduce the models prior to re-export to DirectX file format.
