What are ASM, PAR and PSM Files?

  • Files with the file extension ASM, PAR or PSM are native 3D files of the CAD/CAM software Solid Edge. The ASM file extension is also used by Creo Parametric. Creo files can be recognized by a number after the file extension (*.asm.1, *.asm.2)
  • PAR and PSM are part file formats. PAR files contain so-called solid parts and PSM files contain sheet metal parts. This distinction reflects specific modeling functions.
  • ASM is the assembly file format and is linked to at least one, but usually several PRTs or PSMs and often also other ASMs.
  • Like Siemens NX and SolidWorks, Solid Edge also uses the Parasolid modeling kernel.

Solid Edge Versions

The first version of Solid Edge was introduced in November 1995 and was developed directly for Microsoft Windows. Up to version 4, the ACIS modeling kernel from Spatial was used. With the takeover by Unigraphics Solutions (UGS), the UGS Parasolid modeling kernel was used from version 5 onwards.

UGS was acquired by Siemens in 2008. From 2008 to 2018, the version schemes were ST 1 to ST 10. Since 2019, the release year of the new version has simply been used. The current version is Solid Edge 2024. (02/2024)

File versions created with newer releases cannot be opened with older releases. In such cases, Siemens recommends using the Parasolid exchange format x_t or x_b.

Additional Native Solid Edge File Formats

  • dft Native 2D drawing from Solid Edge, derived from a Solid Edge 3D model
  • pwd Solid Edge welding environment. This file environment has not been developed further since version 17. The functions are now available in the ASM environment.
  • Worth mentioning is the Parasolid modeling kernel used by the software. Parasolid X_T and X_B files are 3D exchange formats without a modification history, but are the first choice for exchanging 3D models between CAD/CAM programs with a Parasolid core such as Siemens NX, SolidWorks and Solid Edge.

Which Program Opens ASM, PAR and PSM Files?

Typically, a Solid Edge installation is used for this. It is also possible to open with CAD/CAM software that has a Solid Edge interface, such as Siemens NX.

The free Solid Edge View supports native Solid Edge parts, assemblies and drawings, but since version 2022 no longer offers measurement functions.

The 3D-Tool CAD viewer opens Solid Edge ASM, PAR and PSM files, but provides extensive measurement and analysis tools. 3D-Tool can be tested free of charge for 14 days.

How Do I Convert Native Solid Edge Models?

If you do not have CAD software with a Solid Edge interface, the design must be exported from Solid Edge to a common 3D exchange format, such as STEP. Parasolid x_t or x_b is recommended for exchange with Siemens NX and SolidWorks.

Converting ASM, PAR and PSM to STEP is also possible with a 3D converter or CAD converter.

3D-Tool Premium includes the 3D-NativeCAD Converter. In addition to native Solid Edge models, this converts models from many common CAD systems into the 3D exchange formats STEP, IGES, SAT and Parasolid X_T supported by many CAD/CAM programs.

Test the Solid Edge Viewer and Solid Edge Converter

3D-Tool is a CAD viewer with many native CAD interfaces, including Solid Edge, and professional measuring functions, demolding analysis and wall thickness analysis.

  • Open and publish ASM, PAR and PSM for the 3D-Tool Free Viewer or as 3D-PDF
  • Open ASM, PAR and PSM and save as STL, 3DS, PLY, WRL, OBJ, or PLY
  • Convert ASM, PAR and PSM to STEP, IGES, VDA, SAT and X_T

Free and non-binding 14-day trial with all functions, the Solid Edge interfaces and the 3D-Native CAD Converter. The trial key activates all 3D interfaces, such as Siemens NX, CATIA, Inventor, STEP, SAT, Parasolid.
