 ## Objetivo
 
-Alinhar o comportamento dos controles Touch Plus (Meta Quest 3) ao padrão pedido:
+Adicionar uma ferramenta de **corte de seção** (clipping planes) nos eixos X, Y e Z — padrão em viewers IFC/BIM. O usuário move sliders por eixo e a peça vai sendo cortada/revelada em tempo real. Implementada como **janela pop-up flutuante** sobre o viewer, com controle de opacidade da própria janela. Sem presets persistidos.
 
-- **Grip** = único responsável por mover a peça (pan, zoom, orbit).
+## UX
-- **Trigger** = apenas seleção, medição e ações pontuais (nunca move/rotaciona a peça).
-- **Thumbstick** = navegação do usuário (teletransporte/recuar/girar a câmera), nunca mais ajuste fino do modelo.
-- **Botão Menu** = mantém comportamento nativo (não tocar).
 
-## Mapeamento alvo
+### Botões na barra `ViewerControls`
+- **"Cortes"** (ícone `Scissors`) — abre/fecha a janela pop-up. O estado dos cortes é independente da janela: fechar não reseta nada.
+- **Lixeira** ao lado, só fica habilitada quando há pelo menos um eixo de corte ativo. Clicar = `resetSection()` (desliga e zera os 3 eixos). Único caminho para zerar.
+- Indicador visual no botão "Cortes" quando há corte ativo (badge ou variante `default`).
 
-```text
+### Pop-up (componente `SectionCutPanel`)
-Mão               Botão              Ação
+- Janela flutuante sobre o viewer (canto superior-direito da área 3D), arrastável pelo header. Não-modal.
-─────────────────────────────────────────────────────────
+- Estilo: `bg-card/X` + `backdrop-blur`, borda industrial, font-mono.
-Esquerda/Direita  Grip (1 mão)       Pan da peça (translação 6DOF, sem rotação)
+- **Header**: título "Cortes de Seção", slider de **opacidade da janela** (20%–100%, default 90%), botão fechar (X).
-Ambas as mãos     Grip + afastar     Zoom uniforme (escala)
+- **3 blocos idênticos** para X / Y / Z, cada um com controle individual:
-Ambas as mãos     Grip + giro oposto Orbitar/rotacionar a peça
+  - Switch on/off do eixo.
-Direita           Trigger            Selecionar componente / adicionar ponto de medida
+  - Switch "Inverter" (flip do lado mantido).
-Esquerda          Trigger            Alternar snap de vértice (já existe)
+  - Slider do nível de corte mapeado ao bbox mundial da peça ativa naquele eixo, valor em mm.
-Direita           Botão A            Desfazer última medida (já existe)
+  - Mini-botões: **Min** · **Centro** · **Max** para saltar a posição.
-Direita           Botão B            Limpar medidas (já existe)
+- Botão **"Recalcular limites"** (re-amostra o bbox depois de calibração/fine-tuning).
-Thumbstick        Frente + soltar    Teletransporte para o ponto apontado
+- Sem botões de salvar/memória.
-Thumbstick        Lados              Snap-rotate da câmera (±30°)
+- Fechar a janela apenas oculta os controles. Reabrir mostra exatamente o estado dos cortes que o usuário deixou.
-Thumbstick        Trás               Recuar o usuário (passo)

-## Mudanças no código
+## Comportamento técnico
 
-### 1. `src/components/three/XRGrabbable.tsx`
+- `gl.localClippingEnabled = true` no `onCreated` do `<Canvas>`.
+- Novos campos em `useModelStore` (não persistidos):
+  - `sectionEnabled: { x: boolean; y: boolean; z: boolean }`
+  - `sectionInvert: { x: boolean; y: boolean; z: boolean }`
+  - `sectionLevel: { x: number; y: number; z: number }` (em metros, mundo)
+  - `sectionPanelOpen: boolean`
+  - `sectionPanelOpacity: number` (0.2–1)
+  - Setters por eixo + `resetSection()` (zera enabled, invert e leva level ao centro do bbox).
+  - Helper `hasActiveSection()` derivado de `sectionEnabled`.
+- Novo componente `<SectionClippingApplier>` montado dentro do `<Canvas>`:
+  - Mantém 3 `THREE.Plane` reutilizáveis. A cada mudança nos campos do store, atualiza `plane.normal` (com sinal flipado se `invert`) e `plane.constant = -level` (axis-aligned, mundo).
+  - Aplica `material.clippingPlanes = ativos` em cada `Mesh` dos grupos registrados em `modelTransforms`. Restaura `[]` ao desligar todos os eixos.
+- Limites dos sliders: bbox mundial agregado dos `getAllModelLocalGroups()`. Calculado quando o painel abre e quando o usuário aciona "Recalcular limites".
 
-- **One-hand grip**: passar a aplicar **apenas translação** (pan). Hoje aplica matriz completa do grip → leva rotação junto. Vou capturar o offset de posição e atualizar só `group.position`, mantendo `quaternion` e `scale`.
+## Arquivos afetados
-- **Two-hand grip**: manter rotação pelo eixo entre as mãos + **forçar `allowScale = true` sempre** (zoom passa a vir do grip, não depende mais do toggle do HUD).
-- Remover a prop `allowScale` da assinatura (ou ignorar e tratar como `true`).
 
-### 2. `src/pages/XRSession.tsx`
+- `src/stores/useModelStore.ts` — novos campos e setters de seção + painel.
-
+- `src/components/three/ModelViewer.tsx` — `localClippingEnabled` no GL; monta `<SectionClippingApplier>`.
-- Remover o estado `allowScale` e os toggles correspondentes nas duas instâncias de `<XRGrabbable>`.
+- `src/components/SectionCutPanel.tsx` (novo) — janela pop-up flutuante com 3 sliders, switches, opacidade.
-- Substituir `<ControllerFineTuning />` por um novo `<ControllerLocomotion />` (ver item 4) — o joystick não deve mais editar `fineTuning` do modelo.
+- `src/components/ViewerControls.tsx` — botão "Cortes" + lixeira condicional.
-- Garantir que `XRHitTestPlacement` só consome `onSelect` (trigger) quando `placementMode === true`; fora disso o trigger é roteado integralmente para `XRControllerMeasure`.
+- `src/pages/Viewer.tsx` — monta `<SectionCutPanel />` na área do viewer.
-
-### 3. `src/components/XRHud.tsx` e `src/components/three/XRHudInWorld.tsx`
-
-- Remover botão/toggle “Permitir escala” (`allowScale`) — agora é sempre via grip duplo.
-- Remover/relabelar o toggle “Movimento livre” (`freeMove`) já que o joystick deixa de ajustar o modelo; manter apenas se ainda fizer sentido para outra função (caso não, remover prop também de `XRSession.tsx`).
-
-### 4. Novo `src/components/three/ControllerLocomotion.tsx`
-
-Componente que substitui `ControllerFineTuning`. Lê `useXR().session` e implementa:
-
-- **Joystick esquerdo (ou ambos, configurável)**:
-  - `axes[1] < -0.7` mantido por ~200 ms → dispara teleport: raycast a partir do controle direito contra `scene.children` no plano horizontal mais próximo; aplica `xrOrigin.position` para reposicionar.
-  - `axes[1] > 0.7` → recua o `XROrigin` em passos de 0.3 m por trigger.
-  - `axes[0]` cruzando ±0.7 (com histerese) → snap-rotate de ±30° no `XROrigin.rotation.y`.
-- Usar a API `XROrigin` já montada em `XRSession.tsx` (referência via `useRef` ou store) para escrever pose.
-- Desligar tudo se `lockedActive` (modelo travado) — locomoção do usuário ainda funciona, só não move o modelo.
-
-### 5. `src/components/three/XRControllerMeasure.tsx`
-
-- Sem mudanças funcionais — já usa apenas trigger e botões A/B. Apenas confirmar que o early-return `(!measureMode && !selectionMode)` continua: quando nenhum dos modos está ativo, o trigger não dispara nada relacionado à medição (e não interfere em `XRHitTestPlacement`, que respeita `placementMode`).
-
-### 6. `src/components/three/XRHitTestPlacement.tsx`
-
-- Garantir que o handler `onSelect` (trigger) verifica `placementMode` antes de colocar o modelo. Hoje o tap-plane invisível pode estar capturando o select mesmo fora do placement — adicionar guarda explícita e `visible={placementMode}`.
-
-## Validação
-
-1. **Desktop SimXR** (devkit): pressionar Q/W (grip simulado) move a peça; pressionar A/S (trigger simulado) não muda pose nenhuma.
-2. **Quest 3 real (passthrough)**:
-   - Grip único arrasta a peça sem rotacionar.
-   - Dois grips afastando = zoom; dois grips em rotação oposta = orbit.
-   - Trigger direito fora dos modos medir/selecionar/colocar = nada acontece.
-   - Trigger direito em modo Selecionar = seleciona componente IFC.
-   - Trigger direito em modo Medir = adiciona ponto com snap.
-   - Joystick esquerdo para frente = teletransporte; lados = snap-rotate; trás = recua.
-3. Logs `[XR][grab]` continuam mostrando início/fim de one-hand e two-hand.
-
-## Fora do escopo
-
-- Não mexer no botão Menu (Universal Menu do Quest é nativo).
-- Não alterar handlers DOM/mouse do modo desktop (Viewer).
-- Não tocar em RLS, store de dados ou backend.
