Extract text from FormIt sketches (AXM)
To convert AXM sketches to another format, you need Autodesk FormIt or other 3D software.
To convert other file formats to the "BIM Sketch Model" file type, you need software like Autodesk FormIt or a similar tool.
The .AXM file extension is primarily the native format for Autodesk FormIt, a conceptual Building Information Modeling (BIM) tool used for architectural sketching and site analysis. These files contain 3D geometry, location data, satellite imagery overlays, and material textures.
While .AXM files are excellent for the early design phases within the Autodesk ecosystem, they pose significant interoperability challenges outside of it. Because the format is proprietary to FormIt, you generally cannot open these files directly in third-party 3D tools like Blender, SketchUp, or Rhino without an intermediate conversion step. Users often find themselves locked out of their own data if they let their Autodesk subscription lapse or if they are working with a client who uses a different CAD standard. Furthermore, older versions of .AXM files may require specific software updates to render correctly, creating versioning headaches for long-term archiving.
To make this data usable in other pipelines, conversion is usually necessary. For continued BIM development, converting to RVT (Revit) or IFC is the standard. For visualization and rendering in software like 3ds Max or Maya, the OBJ or FBX formats provide the best geometry retention. If you intend to 3D print the sketch model, converting to STL is required. For strictly geometric exchanges with solid modelers (like SolidWorks), the SAT (ACIS) format is often the most reliable bridge.
Convert.Guru analyzes your AXM file, detects the exact format, and lets you read the text inside.
Users also converted AXMB, FBX, M21 and MP21 files.
If you want to convert AXM file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Autodesk FormIt or similar software from the "3D Architectural Sketching" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to AXM, try Autodesk FormIt or another comparable tool in the "3D Architectural Sketching" 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 AXM converter.
