Convert STEP to XT

Understanding the STEP and XT file formats

STEP (Standard for the Exchange of Product Data), with file extensions like .step or .stp, is a widely used neutral CAD file format for 3D model data exchange. It is based on the ISO 10303 standard and is supported by most major CAD applications.

XT files refer to the Parasolid XT format, a proprietary geometric modeling kernel developed by Siemens PLM Software. XT files are used for representing 3D geometry and are commonly used in engineering and manufacturing workflows.

Why convert STEP to XT?

Converting a STEP file to an XT file is often necessary when you need to work with Parasolid-based CAD software, such as Siemens NX, Solid Edge, or other applications that use the Parasolid kernel for modeling and editing 3D geometry.

How to convert STEP to XT

To convert a STEP file to an XT file, you will need a CAD application or a dedicated file converter that supports both formats. Here are the general steps using Siemens Solid Edge as an example:

1. Open Solid Edge.
2. Go to File → Open and select your STEP (.step or .stp) file.
3. Once the file is imported, go to File → Save As.
4. In the Save as type dropdown, select Parasolid (*.x_t, *.x_b).
5. Choose your desired location and click Save.

Best software for STEP to XT conversion

• Siemens Solid Edge – Excellent support for both STEP and Parasolid XT formats.
• Siemens NX – Native Parasolid support and robust import/export options.
• Autodesk Inventor – Can import STEP and export to Parasolid XT.
• Online converters – Some online services like CAD Exchanger or AnyConv offer STEP to XT conversion, but for best results and data integrity, use professional CAD software.

Important tips

• Always verify the converted XT file in your target application to ensure geometry and features are preserved.
• Some complex assemblies or features may not translate perfectly; manual adjustments may be required.
• Keep backup copies of your original STEP files before conversion.
