What is Nova Bounds

Nova Bounds is a Blender addon focused on efficient multi-object selection and real-time bounding box manipulation.

At its core, it provides instant, interactive bounding boxes for any number of selected objects. Visualize dimensions clearly, adjust overall size on-the-fly, and choose from multiple calculation modes, pivot options, and global or aligned coordinates. This gives you precise control over positioning without repeated individual tweaks—especially valuable in complex scenes.

It also introduces bound selections for smarter hierarchy management: one-click auto-inclusion of children, parents, or siblings, plus direct collection selection from the Outliner. Color-coded overlays clearly indicate selection relationships, even through occluding geometry.

Automatic performance optimization keeps it smooth in dense scenes, with customizable overlay and bounding box visuals.

Designed for daily professional use, Nova Bounds cuts significant time from routine selection, measurement, and repositioning tasks—so you spend more time creating.

Main Features

 Real-Time Multi-Object Bounding Box 

Get instant bounding box visualization and measurements for your entire selection.

• Multiple calculation modes — Overall bounds, bounding box centers, or object origins
• Flexible orientation — Global world space or aligned to active object rotation
• Precise or fast calculations — Toggle between speed and accuracy based on your needs
• Interactive dimension adjustment — Resize and reposition objects on-the-fly using your chosen pivot point (bounds center, active object, or 3D cursor)
• Real-time measurements — See dimensions in scene units as you work
  
  

 Smart Bound Selections 

Intelligent selection management for complex hierarchies and collections.

• Auto-include relationships — Children, parents, or siblings at immediate or full hierarchy depth
• Sibling name filtering — Quickly select related objects by matching names
• Direct collection selection — Select objects within collections from the Outliner with full hierarchy support
• One-click commits — Transfer bound selection to direct selection anytime
  
  

 Crystal-Clear Visual Feedback 

Color-coded overlays show exactly what's selected and how.

• Relationship indicators — Distinguish direct selections from children, parents, siblings, and collected objects at a glance
  
• See-through display — Maintain visibility even when selections are obscured by geometry
• Customizable appearance — Configure colors, overlay styles, and detail levels
  
• Universal highlighting — Works with any object type, including empties and non-mesh objects
  
  

 Performance-Optimized & Customizable 

Built for professional daily use in scenes of any complexity.

• Automatic performance management — Smart detail degradation maintains smooth viewport performance in heavy scenes
• Flexible display modes — Choose from filled overlays, bounding boxes, or point displays
• Streamlined interface — Collapsible panels with quick on/off toggles for all features
• Shading mode control — Define which viewport modes display overlays and bounds

Troubleshooting

Nova Bounds pushes the boundaries of what's possible with Blender's current API. If you experience any issues, please contact me so we can find out whether they can be resolved or if they represent Blender API limitations.

Known Limitations:

• Multiple Outliners — Selection synchronization between multiple Outliner windows may be inconsistent due to Blender API constraints
• Mixed selection methods — Combining selections in the viewport and Outliner simultaneously may produce inconsistent results
• Bounds in Eevee shading mode — Bounds overlay in Eevee might be hidden when viewport overlays are disabled
