Learn how to import and export Parasolid (X_T and X_B) files in Shapr3D, including supported geometry, output formats, and compatibility considerations.
What is a Parasolid file?
Parasolid is a geometric modeling kernel used by Shapr3D and other CAD applications to represent precise 3D geometry. Parasolid files are commonly used to exchange solid and surface geometry between compatible CAD systems.
Parasolid files are available in two formats:
- X_T: A text-based Parasolid file format.
- X_B: A binary Parasolid file format.
Both formats are used to transfer precise CAD geometry without converting it into a polygonal mesh.
Import Parasolid files into Shapr3D
Shapr3D supports importing Parasolid X_T and X_B files. Imported solid and surface geometry can be used and modified with Shapr3D's modeling tools.

Export Parasolid files from Shapr3D
Export designs as Parasolid files to transfer precise solid geometry to compatible CAD applications, including Siemens NX, SolidWorks, Solid Edge, and Onshape.
Parasolid output format
Under Output Format, choose the encoding for the exported Parasolid file:
- ASCII: Exports a text-based Parasolid file in X_T format.
- Binary: Exports a binary Parasolid file in X_B format.
Additional export settings
You can also configure the following settings:
- File Name: Enter a name for the exported file.
- Include Hidden Items: Include hidden items in the export.
- Save Each 1st-Level Item Separately: Export first-level items as separate files, with file names based on their item labels.

Considerations when using Parasolid files
Precise CAD geometry
Parasolid files preserve precise solid and surface geometry, unlike mesh formats such as STL and OBJ. They do not preserve Shapr3D's parametric design history.
Application compatibility
Parasolid is particularly useful when exchanging geometry with applications that use the Parasolid modeling kernel. For other CAD applications, STEP may provide a more broadly compatible exchange format.
