STEP File Viewer

- Improved model zoom control for smoother mouse wheel and trackpad zooming, making view adjustments more precise. - Improved the recent files list with quick filename filtering and a clearer Clear All action. - Improved STEP file compatibility, fixing some models that failed to load or showed abnormal faces and holes.

- View orientation has been optimized for the Z-up convention commonly used in industrial and mechanical CAD. - The bottom-right ViewCube has been further improved, keeping standard views, rotate, roll, and reset actions in sync with the model view.

- Added exploded-parts faceted STEP export — save each exploded part as a separate STEP file, with batch export to a single folder - Added an explosion radius slider (1×–20×) to the exploded-parts panel - Replaced the corner view helper with a new view cube — tap faces for front, top, side, and other standard views; use the surrounding buttons to rotate and roll the model

- Added per-file deletion in the recent files list, plus confirmed clear-all when the list gets longer, making import history easier to manage - Improved STEP color loading, including XCAF, instance, face-level, and subshape colors, reducing gray or mismatched colors in colored models - Improved view reset: tap the quick action icon to return directly to the default view without an extra confirmation prompt

- New hole feature auto-detection and measurement — scan all circular holes in the model with one tap, with quick diameter/radius annotation - New bounding box measurement — automatically calculate length, width, height, and volume of parts or assemblies - New assembly part recognition scan — measure part bounding box dimensions with one tap - Exploded view now supports exporting selected parts to separate files; the part list panel allows quick switching and locating of part views - Improved measurement focus camera — one tap to auto-adapt to the optimal viewing angle - Exploded view measurement rules now restrict measurements to within the same part, preventing cross-part annotation misalignment - New PMI/GD&T information browser panel (located in the sidebar's Model tab), supporting filtering by type, source, and confidence level to explore product manufacturing information
