How to convert STEP (.step,.stp) to XGL (ZGL)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

STEP

STEP is the defacto 'go-to' MCAD translation file format when you do not have access to the original CAD part and assembly files. It is a long standing 'industry standard' that can be used to move MCAD/CAD file assets into many downstream 3D programs and file formats. Okino's PolyTrans|CAD provides for a defacto 3D STEP file conversion solution used by the world's primary & professional engineering, aerospace, military, corporate, animation/multi-media and VR/AR industries. STEP uses the .stp and .step file extensions.

STEP files are readable ASCII files which encode CAD parts and assembly information. Most respectable MCAD modellers will actively and correctly support the STEP AP203 and AP214 file formats. STEP was originally developed to supercede the IGES file format but has mostly supplemented but not replaced IGES. You would either want to export a "STEP AP214" file or an "IGES BREP solids" file depending on the MCAD modeller.

A much deeper overview plus explanation of STEP, and how it can be best used + understood, is outlined in this Okino WEB page.

Most people initially come to Okino asking for a STEP importer but it should only be used in specific situations as outlined in our "CAD Data Sourcing Suggestons and Rules".

XGL

XGL/ZGL is a legacy 3D polygonal mesh file format that had been created by the RealityWave company in the late 1990s. AVEVA purchased RealityWave and integrated the file format into their PDMS products. Some other companies had added XGL/ZGL exporters into their software such as CATIA, MicroStation and Solid Edge.

As explained on the Okino ZGL import converter page, files can be imported from AVEVA PDMS via the ZGL file format and AVEVA's 'rvm2zgl.exe' program. However, in more recent years, you can export DWF-3D files from AVEVA PDMS and import those files directly into Okino software.
