Bool Tool

Quick boolean operators and tools for hard surface modeling.

Add-on by nickberckley

This extension was part of Blender 4.1 bundled add-ons

Old and iconic Bool Tool has been updated, modernized, enhanced, and pumped with new features for Blender 4.2, including new Carver tools ported from the add-on with the same name (also bundled with Blender in the past).

Bool Tool offers operators for quickly applying boolean modifiers (brush booleans), performing destructive cuts (auto boolean), or using workspace tools in object and edit modes to cut object with custom shapes! As well as utility features for managing, removing, and applying boolean modifiers, and all around helping in hard-surface modeling workflow.

You can read (way too) detailed documentation of the add-on here!

Add-on is developed and maintained on GitHub.

We welcome contributions from people who are good with bpy and better than us at math.

If you want to take a part in development take a look at Help Wanted section, or propose your ideas!

Users can also contribute by providing screenshots and graphs that can be useful for documentation.

If you want to make a video about Bool Tool and have questions you can reach out in discussions or at BlenderArtists.

You can also help out by making bug reports!

What's New

2.0.0 December 9th, 2025

Bool Tool v2.0 comes with updates exclusively to Carve tools. Everything mentioned below refers to those tools.

Added

Surface Alignment - cutters can be drawn on mesh surfaces.
Manual depth option - control the extrusion of the cutter during the modal.
3D Cursor & Grid alignment.
Advanced settings for surface alignment in the "Shape" dropdown menu.
The display type of the cutter can be changed on the tool level in the "Cutter" dropdown menu.
Bevel Profile property in tool settings.
Property for choosing the cutter's origin point in the "Cutter" dropdown menu.

Changed

Bevel & Array are now non-destructive (added on the cutter as modifiers). Found in the new "Effects" dropdown menu.
All three tools are now non-destructive by default.
Improved behavior of setting rotation, bevel, and array gap during modal.
Circle Carve tool now creates perfect circles by default (fixed aspect and center origin).
More accurate auto depth and 3D cursor depth.
"Auto Smooth" is no longer destructive and adds a "Smooth by Angle" modifier on the cutter.
Destructive mode applies modifiers based on the "Apply Order" add-on preference.
Created cutters keep their rotation unapplied.
Improved tool settings UI in Properties editor and 3D Viewport's sidebar.
Status bar displays icons instead of just text.
Having objects selected is now required for the tool to initialize.

Removed

Snapping to grid with Ctrl was removed. It will be replaced with more complex snapping options in future versions.
The "Closed Polygon" option for the Polyline tool is removed. It's always closed now.
Array rows and columns use the same "Gap" property now, instead of separate ones.
"Direction" properties for array rows and columns removed. It's automatically set now.

Known Issues

Array columns and rows might go in the wrong direction. Try drawing the shape from a different direction if that happens.
Rotation changes the cutter position if the Circle Carve tool uses "Edge" origin.
If "Fade Inactive Geometry" is enabled in edit mode, the cutter overlay is much darker red.
