How to convert files from Rhino3D
to X_T?

Rhinoceros (typically abbreviated Rhino, or Rhino3D) is a commercial 3D computer graphics and computer-aided design (CAD) application software developed by Robert McNeel & Associates. It is used in industries including architecture, industrial and product design, in multimedia and graphic design and runs on Microsoft Windows and OS X. Rhino uses Grasshopper, a visual scripting language add-on, developed by Robert McNeel & Associates.

Rhino is based on the NURBS mathematical model, so it focuses on producing precise representations of curves and freedom surfaces. It allows users to create, edit, analyse, and visualize NURBS curves, surfaces, solid bodies, point clouds and polymeshes.

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.
