SolidWorks (.sldprt) to Parasolid (.x_t / .x_b) Lossless Kernel Converter
SolidWorks uses the Siemens Parasolid geometric modeling kernel as its core mathematical engine. When transferring data to CAM systems (Mastercam, hyperMILL) or other Parasolid-based CAD systems (Siemens NX, Solid Edge, Onshape), converting to STEP incurs a slight format translation penalty. Exporting directly to Parasolid .x_t provides 100% mathematically identical geometry with zero surface edge drift.

Confidential IP & Safety Warning
Parasolid transmit files store the mathematical equations of all solid boundaries. Always ensure your NDA permits sharing raw 3D geometry with external CAM vendors.

Match the Parasolid Schema Version Number
If a machine shop’s CAM system throws an Incompatible Parasolid Schema error, export the .x_t file targeting an older schema version (e.g., v28 to v31) to ensure backward compatibility.
Choose Between .x_t (ASCII) and .x_b (Binary)
Use .x_t (text) for standard email exchange and debugging. Use .x_b (binary) for massive assembly files with hundreds of complex parts to halve the file size on disk.
Enjoy Perfect B-Rep Surface Boundary Continuity
Because SolidWorks and NX share the identical Parasolid kernel, complex fillets, drafts, and lofts will never tear or produce open quilt gaps during .x_t interop.

SolidWorks SLDPRT to Parasolid X_T Converter FAQs
SolidWorks, Siemens NX, Solid Edge, and Mastercam all use the Parasolid geometry kernel. Exporting to .x_t transfers native kernel data directly with zero translation error or edge stitching.
