How to convert 3D PDF
to Parasolid?

3D PDF

3D PDF is a PDF file with 3D geometry inside. Using any 3D PDF enabled viewer, rotation, zoom and part selection is available within the 3D view.

3D PDF is just like a normal PDF (Portable Document Format) file, which contains a 3D view somewhere on some page. Just like a PDF containing an embedded image, except when you put the mouse over it, you can rotate, zoom, pan and explore the scene in 3D (three dimensions). The file actually contains a 3D geometric representation of the scene, not just images from different viewpoints.

Parasolid

Parasolid file format is native for Parasolid geometrical kernel. Today it is widely used in a range of applications, including SolidWorks, SolidEdge, NX, Microstation, Ansys, Abaqus and others. Parasolid has two primary file extensions: .x_t, which is text based, and .x_b – binary-based format. Parasolid is also used to provide precise geometrical definitions of parts in JT files (as XT B-Rep data segments). CAD Exchanger can read files compliant with the entire range of Parasolid file format (schema) starting from v0.15 and up to version 32 (as of time of writing this page). Likewise, CAD Exchanger writes file compliant with all Parasolid schemas.
