Conversion from X_T to SLDPRT is not supported yet :(

A file with extension X_T (Parasolid text files) is used by the Parasolid core created by Siemens PLM Software. It is being developed as a standard export format for distributing Parasolid CAD models.

The X_T file is a set of structured data containing information about the features of the model construction, the topology of its structural elements, color scheme, coordinates of drawing primitives, etc.

The X_T extension is unpretentious to adapt and can be exported / imported for use in a wide variety of CAD systems. It is stored in text format and can be exported and imported using a variety of other computer-aided design programs.

X_T files are used instead of the old version of the XMT_TXT and XMP_TXT files, which are less used than X_B (Parasolid binary files), and store the same data, but in binary format.

A SLDPRT file contains a 3D part created in the SOLIDWORKS design software.

Multiple SLDPRT parts can be independently modified and combined into a single SLDASM assembly file. If one SLDPRT part belongs to several assemblies, then after modifying it, the changes will appear in all assemblies.

SLDPRT are proprietary files with closed specifications. Nevertheless, some APIs (like CAD Exchanger SDK) provide the facility to read and convert them to other formats.

In addition to SOLIDWORKS software, SLDPRT files are supported by Autodesk Fusion 360.
