Convert SLDPRT to X_T

Verified by Adam B.· reviewed by FE Editorial ·updated Jul 15, 2026
QUICK ANSWER
Is it possible to convert SLDPRT to X_T?
Yes - SLDPRT converts to X_T.

The fastest path is our free converter above - upload your .sldprt and get a .x_t file back in seconds. If you have SOLIDWORKS, use File > Save As > Parasolid (*.x_t) for the most reliable result. Either way, the SOLIDWORKS feature tree is not saved - only the final solid geometry transfers.

Why convert SLDPRT to X_T?

Engineers export .sldprt to .X_T to share solid geometry with Parasolid-based CAD tools - such as Siemens NX and Solid Edge - without the recipient needing a SOLIDWORKS license. Because SOLIDWORKS and those applications share the Parasolid kernel, solid bodies transfer cleanly with no additional kernel translation. X_T is also a standard neutral handoff format in manufacturing and simulation workflows.

How to convert SLDPRT to X_T

SOLIDWORKS - File > Save As BUILT-IN

Open the part, choose File > Save As, and select Parasolid (*.x_t) from the format list.

Autodesk Inventor APP

Import the .sldprt via Inventor's AnyCAD direct import, then export as Parasolid .x_t through File > Save As.

TransMagic APP

Load the .sldprt and export to .x_t; TransMagic is a dedicated CAD translator and supports batch conversion.

FreeCAD FREE

Open the .sldprt in FreeCAD and use File > Export, selecting the Parasolid format.

.SLDPRT SOLIDWORKS Part File

A SLDPRT file is a single 3D part designed in SOLIDWORKS, the CAD application from Dassault Systèmes. To view it without buying SOLIDWORKS, use the free eDrawings Viewer (Windows, Mac, iOS,…

.X_T Parasolid Model (text transmit file)

An X_T file is a 3D CAD solid model in Siemens' Parasolid format, used to share exact part geometry between programs like SolidWorks, Solid Edge, and NX. To view one for free, use eDrawings…

Quality & what to watch

  • The SOLIDWORKS feature tree - sketches, extrudes, fillets, and parametric relations - is not saved; the target app receives a dumb solid with no editable history.
  • ​.x_t (text) and .x_b (binary) hold identical geometry; .x_t is human-readable while .x_b produces a smaller file.
  • If the target CAD runs an older Parasolid version, import may fail - SOLIDWORKS lets you choose the Parasolid schema version in the Save As dialog.

Frequently asked questions

Can I convert SLDPRT to X_T without SOLIDWORKS?
Yes - our free converter above works without a SOLIDWORKS license. Autodesk Inventor and TransMagic are paid alternatives that also support this format pair.
What is the difference between X_T and X_B?
Both hold identical Parasolid geometry. .x_t is plain text (larger, human-inspectable); .x_b is binary and produces a smaller file.
Does X_T keep my SOLIDWORKS feature history?
No - X_T stores only the final B-rep solid. Sketches, dimensions, and feature history exist only in the original .sldprt.
Which programs can open an X_T file?
Any Parasolid-based CAD application, including Siemens NX, Solid Edge, Autodesk Inventor, PTC Creo, and FreeCAD.
