Convert XMT_TXT to IAM

Understanding xmt_txt and iam file formats

XMT_TXT is a text-based intermediate file format used primarily by Siemens NX (formerly Unigraphics) for the exchange of 3D CAD data. It stores geometric and assembly information in a human-readable format, making it useful for interoperability and data migration between different CAD systems.

IAM is the file extension for Autodesk Inventor Assembly files. These files contain references to multiple part files (IPT) and define how these parts fit and work together in a 3D assembly. IAM files are essential for managing complex mechanical designs in Autodesk Inventor.

How to convert xmt_txt to iam

Direct conversion from xmt_txt to iam is not natively supported by most CAD software, as these formats are proprietary to different platforms. However, you can achieve the conversion through an intermediate step using a CAD program that supports both import and export of compatible formats.

Recommended software for conversion

• Autodesk Inventor: While Inventor does not directly import xmt_txt files, you can first import the xmt_txt file into Siemens NX or another compatible CAD system, then export the assembly as a neutral format such as STEP (.stp/.step) or IGES (.igs/.iges). Afterward, import the STEP or IGES file into Autodesk Inventor and save it as an IAM file.
• Siemens NX: Open the xmt_txt file, then use File → Export → STEP or File → Export → IGES to create a neutral file for Inventor.

Step-by-step conversion process

1. Open the xmt_txt file in Siemens NX or a compatible CAD program.
2. Export the assembly to a neutral format using File → Export → STEP or File → Export → IGES.
3. Open Autodesk Inventor and use File → Open to import the STEP or IGES file.
4. Once imported, save the assembly as an IAM file using File → Save As.

Tips for successful conversion

• Check for data loss or missing constraints after importing into Inventor, as some features may not translate perfectly between formats.
• Use the latest versions of both Siemens NX and Autodesk Inventor for best compatibility.
• Consider using third-party CAD conversion tools like Autodesk AnyCAD or CAD Exchanger for more complex assemblies.
