Parasolid

[1] Parasolid also includes tools for direct model editing, including tapering, offsetting, geometry replacement and removing feature details with automated regeneration of surrounding data.

Parasolid also provides wide-ranging graphical and rendering support, including hidden-line, wireframe and drafting, tessellation, and model data inquiries.

Parasolid parts are normally saved in XT format, which usually has the file extension .X_T.

To use Parasolid effectively, software developers need knowledge of CAD in general, computational geometry, and topology.

Parasolid is available for Windows (32-bit, 64-bit and AArch64), Linux (64-bit and AArch64), macOS (Intel and Apple silicon), iOS, and Android.
