Modern versions of SketchUp (2021–2024) have added native features like "Flip Along" and improved axis tools. However, the BZ Toolbar offers specific micro-tools that native SketchUp still lacks.
Developed by the prolific extension author (often abbreviated as "BZ"), the BZ Toolbar is a collection of small, powerful scripts designed to solve specific, annoying problems in SketchUp. While the original "BZ Toolbar" has evolved and some features have been absorbed into other packs (like the famous "TT_Lib" or "SketchUcation Tools"), the legacy and core functionality remain vital for professionals and hobbyists alike.
Keep BZ Toolbar installed only for BZ Axis and BZ Cleanup . For face reversing, switch to the newer "Eneroth Face Director."
