Extract text from InfraWorks models or scores (IWM)
To convert IWM files to another format, you need Autodesk InfraWorks or other 3D software.
To convert other file formats to the "Conceptual Engineering Model" file type, you need software like Autodesk InfraWorks or a similar tool.
The .IWM file extension is primarily associated with two distinct applications: Autodesk InfraWorks and iWriteMusic. In the civil engineering sector, an .IWM file acts as a conceptual 3D model configuration file for Autodesk InfraWorks. It often functions alongside a larger .sqlite database and a connected data folder to render massive infrastructure projects. In the music sector, it serves as a project file for the iWriteMusic iOS application, storing musical scores, notation data, and composition metadata.
The main disadvantage of the .IWM format is its heavily proprietary nature. For civil engineers, opening an InfraWorks model requires a costly desktop subscription and heavy local processing power. The file itself is useless without its linked database folder. For musicians, the iWriteMusic score format is locked into a specific mobile ecosystem, making collaboration with users of standard software like Sibelius or Finale extremely difficult.
Standard online converters usually fail to process .IWM files because they lack the specific engines needed to render 3D terrain or interpret proprietary music staves. Therefore, exporting to standard formats like DWG, RVT, PDF, or MusicXML must typically be done within the original software.
However, there is a practical workaround. Many .IWM files are structured as underlying JSON (for InfraWorks) or plist (Property List, for iWriteMusic) data. Just drag and drop your file into convert.guru to identify the format, view its internal text structure, and convert it when possible. Even if full 3D rendering or audio playback is impossible outside the native app, our tool can extract valuable raw data, text strings, and configuration settings from the file.
Convert.Guru analyzes your IWM file, detects the exact format, and lets you read the text inside.
Users also converted TTP, VTR and SAM files.
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 "Conceptual Civil Engineering Model" 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 "Conceptual Civil Engineering Model" category.
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.
