Official LWJ Software Page
LWJ provides Windows software for STEP, IGES and STL workflows. Use GeomCatalog to organize and search 3D CAD files, then open selected models in StepGeomChecker for detailed inspection, measurement and manufacturing review.
The pages are written for English search intent instead of literal translation. The content focuses on Windows, STEP/IGES/STL, practical inspection and CAD-data reuse.
Register CAD data in GeomCatalog, browse thumbnails and narrow files by metadata, tags or comments.
Open the selected model in StepGeomChecker to check geometry, sections, dimensions and mass properties.
Share review results, prepare quotation checks and confirm geometry before manufacturing.
Both tools target manufacturing workflows where STEP, IGES and STL files need to be found, reviewed and communicated quickly.
A free Windows viewer and measurement tool for STEP, STP, IGES, IGS and STL files. Use it for geometry review, section checks, dimension measurement, mass properties and manufacturing inspection.
A Windows 3D CAD data catalog for organizing and searching STEP, STP, IGES, IGS and STL files with thumbnails. It is intended as a practical entry point for CAD data management and reuse.
Use GeomCatalog as the front-end catalog and StepGeomChecker as the inspection tool. This separates file discovery from technical model review.
