The Problem

You drilled a perfect vent grille again — and you'll rebuild it in every future project. Re-appending objects, re-aligning them to surfaces, re-creating the Boolean: ten minutes of identical work, forever.

The Solution

Boolean Vault is a personal library of reusable Boolean cutters.

1. Select any mesh → Save Selected as Cutter (geometry + transform, on disk).

2. In a NEW project, click the thumbnail → the cutter follows your cursor as a ghost, aligned to the face under it.

3. Left-click to place — the Boolean modifier (Difference/Union/Intersect) is created on the target automatically.

Key Features

- Cross-project library that survives without the .blend file

- Drag-out ghost placement with live tuning: Scroll = scale, Ctrl+Scroll = spin, Shift/Alt+Scroll = tilt, MMB = depth

- Auto half-through-cut (never floats off the surface)

- Search, categories, tags, favorites

- Auto thumbnails + paste your own screenshot (Windows)

- Recall placed cutters and re-edit their mesh anytime

- Workspace kept clean: cutters park in an auto-hidden collection
