How to convert Autodesk Inventor (.iam,.ipt) to Form/Z (.fmz,.fml)?

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.



Form/Z is one of those power house 3D modelers with a deep history. It is a general-purpose solid and surface modeling software which offers 2D/3D form manipulating and sculpting capabilities.

Okino has known of, and associated with, Form/Z since 1994. Being a top notch modeler it has many methods to export 3D geometry data to Okino's conversion software. Of note are: ACIS SAT, DXF/DWG, IGES, STEP, STL, VRML and Wavefront OBJ.
