Boolean MasterBoolean-style cuts, clean quad topology
Place holes, slots, pockets and bosses with the mouse. Boolean Master rebuilds the surface around them as clean, all-quad topology with support loops — ready for Subdivision Surface, with no n-gons to clean up.
Live Feature Demos
Recorded in Blender with the add-on itself. Everything below is in the full version; the Lite edition cuts Circle holes and lets you change their size.
Click. Size. Cut.
Press Shift+Q, move over the surface and click the center. The live preview snaps to vertices, edge middles and face centers, Ctrl+Wheel sizes it and a second click cuts. The plain wheel still zooms the view.
Change it after the cut
Press F9 to change the shape, size, segments, corner ratio, rotation or cut type. Every change is redone from the original mesh, so nothing piles up.
Drag to draw slots
Press, drag and release to draw a Rounded Rectangle or Rectangle from end to end. The angle snaps to 15° and the center to the nearest vertex or edge middle; Alt+Wheel rotates, hold Ctrl to place freely.
Arrays in one placement
R cycles Linear X, Linear Y and Radial. Shift+Wheel sets the count (2–32), P or Shift+Alt+Wheel the spacing. Every copy is previewed, and the whole row is cut — or refused — as one step that one Ctrl+Z undoes.
Mirror across the origin
X, Y or Z mirrors the hole across the object origin. Both sides are previewed exactly and cut together, also on curved meshes.
Bosses and ribs
D switches to Extrude: the outline rises along the surface normal and closes with quad walls and a quad cap. E types the height, Ctrl+Alt+Wheel changes it.
Through, Pocket or Extrude
Turn the same outline into a hole, a recess or a boss in F9, then tune depth, height and corner ratio until it fits.
Curved, real-world meshes
The cut follows the surface. Quad grids are cut on the grid; strips, triangles, n-gons and areas near an earlier hole get a local quad patch, and the rest of the mesh stays untouched.
All-quad, SubD-ready
Every result is validated as all quads with support loops. Match Grid keeps dense surfaces flat, Auto Grid prepares a coarse Plane or Cube — and if a cut cannot be made cleanly, nothing changes.
Lite or Full
Lite is for trying the topology on your own meshes. Upgrade any time — installing the full ZIP replaces Lite.

What Boolean Master Adds
A focused hard-surface tool: cut, keep the topology clean, move on.
1Live placement HUD
Every setting is listed next to the cursor with its key — no dialogs.
2Five shapes
Circle, Square, Rectangle, Rounded Rectangle and Triangle, plus drag-drawn slots.
3Three cut types
Through holes, Pocket recesses and Extrude bosses with quad walls.
4Arrays and Symmetry
Linear X / Y and Radial copies, mirrored on X / Y / Z, in one placement.
5F9 redo
Change any setting after the cut; it is recomputed from the original mesh.
6SubD support
Support loops or crease, Match Grid, Auto Grid and Auto Smooth.
7Custom outlines
Cut a closed Curve or Text object — a logo, a letter, an imported SVG.
8Safe by design
All-quad validation on every cut; refused cuts leave the mesh unchanged.
Workflow
Requirements
- ✓Blender: Blender 4.2 or newer, installed as an Extension. Tested on Blender 4.5 LTS and 5.2.
- ✓Platform: Tested on Windows 11. Pure Python — no external dependencies, no internet access.
- ✓Mesh objects: Object Mode and Edit Mode (the active face is used in Edit Mode).
- ✓Clean setup: No Blender settings are changed; keys are added only when they do not conflict.
-
✓Install target:
boolean_master-0.5.1.zip(orboolean_master_lite-0.5.1.zip) via Edit > Preferences > Get Extensions > Install from Disk, or drag and drop the ZIP onto the Blender window.
Limitations
- 1UVs: UVs inside the rebuilt area are not preserved.
- 2Object scale: Apply non-uniform object scale for exact sizes.
- 3Custom outlines: No holes inside an outline yet (the middle of O, A, e); slots narrower than about two mesh cells are refused; Array, Symmetry and the live preview are not available for them.
- 4Concave Pocket / Extrude: A concave custom outline whose floor or cap would fold is refused — use Through.
- 5Earlier patches: Cutting into a previous patch can rebuild its nearby support loops; long-strip rows can be slightly oblique.
- 6Not included yet: Booleans between two objects, Bevel and history / re-edit of older cuts are planned. Boolean Master cuts its own shapes and outlines.
Cut clean. Stay in quads.
Installation, every key, F9 settings and troubleshooting are in the Documentation tab.
