The QuickBool add-on was developed to increase workflow when working with boolean operations in Blender. Avoid repetitive tasks by using click and drag features.
- Non-destructive workflow
- Operations at hand
- Use custom objects
- Click & drag system
- Undo operations or errors and keep system running
It is available on Gumroad, where you can see the tool in action.
