Conversion from Parasolid to SLDASM is not supported yet :(

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.

SLDASM is a SOLIDWORKS Assembly File. It refers to a SOLIDWORKS 3D assembly, which consists of several SOLIDWORKS part files (SLDPRT). An assembly file itself may contain some children SLDASM files, as well as some SLDPRT part files.

SLDASM are proprietary files with closed specifications. Nevertheless, some APIs (like CAD Exchanger SDK) provide the facility to read and convert them to other formats.

Software applications like Autodesk Fusion 360, Okino PolyTrans, and AMADA SheetWorks can import and render SLDASM files created with SOLIDWORKS.
