Scale Bars
The Scale Bars branch holds the scale-bar reference objects placed on the model with Annotations → Scale Bar, which offers a 1 m, 5 m or 10 cm bar or a triaxial 5 m scale. Each bar is a real object in the scene, so it reads correctly from any distance and in screenshots and videos.
Context menus
The branch header shows the standard group menu, and each scale bar shows the standard item menu. Both are listed on the Standard Item and Group Menus page.
