How to convert Autodesk Inventor (.iam,.ipt) to DWG (AutoCAD, DXF)?


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.

     

DWG

DXF and DWG are the native file formats of the Autodesk AutoCAD product since 1982. DWG is the binary file variation to the ASCII DXF file format. These files can be viewed by many programs including Autodesk's free DWG TrueView application. It is a closed file format but has been documented by the Open Design Alliance.

At Okino we consider DXF/DWG to be one of the worst 3D file formats when translating 3D model data between applications (depending on its contents). There is very little understanding about this in the 3D graphics world. As outlined in our "CAD Data Sourcing Suggestons and Rules" page you should ideally use the DWF-3D file format when sourcing from either AutoCAD, Navisworks, Revit and optionally Autodesk Inventor.

Due to deep history, Autodesk software can embed ACIS SAT "BREP solids" data in some of its DXF/DWG files. This is the ideal case as the "BREP solids" geometry definitions lead to cleaner and higher fidelity MCAD file conversions. But even so, it would generally be a safer bet to use a STEP AP214 or "IGES BREP solids" file in such cases.
