STEP File Viewer

- 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
