To convert other file formats to the "Civil Engineering Model" file type, you need software like Autodesk InfraWorks or a similar tool.
About IWM files
The .IWM extension typically refers to a model file created by Autodesk InfraWorks, a comprehensive civil infrastructure design platform. These files act as the central database for large-scale engineering projects, often storing road layouts, drainage systems, and terrain data. A significant difficulty for engineers is that .IWM files are deeply proprietary and strictly version-dependent; sending just the single file often results in errors because the associated data folders are missing. Furthermore, they are essentially unreadable outside the Autodesk ecosystem. To collaborate with stakeholders who don't have an expensive CAD subscription, users often need to convert these models to OBJ or FBX for 3D visualization, or IMX for data exchange.
Alternatively, .IWM files are generated by iWriteMusic, a mobile music notation app. In this context, the file contains proprietary song data, lyrics, and chord progressions. Musicians frequently struggle to share these projects with bandmates who don't use the specific app. The best solution is converting these notation files to PDF for printable sheet music, MIDI for audio playback, or MusicXML to import the composition into desktop software like Finale or Sibelius.
Convert.Guru analyzes your IWM file, detects the exact format, and lets you read the text inside.
If you want to convert IWM file to MP4, AVI, MOV, WMV, FLV, WEBM, MKV, M4V, 3GP, OGV, ASF or RM, you can use Autodesk InfraWorks or similar software from the "Civil Infrastructure Design" category. In the File menu, look for Save As… or Export….
To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to IWM, try Autodesk InfraWorks or another comparable tool in the "Civil Infrastructure Design" category.
The IWM Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IWM converter.
