Parasolid is a geometric modeling kernel. Parsolid is mainly used in all PLM Software (NX, SolidEdge ...) but many others CAD systems  use Parasolid as a geometry kernel or interoperability format. Parasolid has commonly  .x_t and .x_b file extensions. Most Parasolid files includes only 3D solids and/or surface data - 2D data such as lines and arcs are nor currently supported.

CAD Interop distributes several softwares to view, translate and compare Parasolid files. Find below the list of our solutions compatible with Parasolid format:
