+# Assemble tool and Auto-fit
+
+## What it is
+
+EdgeSlicer adds stronger **assembly** and **auto-fit** tools so multi-part models can be mated and merged for printing without juggling them by hand.
+
+Two related entry points:
+
+- **Auto-Fit Assembly** (object / selection menu) — right-click a multi-selection: the largest part stays fixed; the rest mate to it by matching faces, holes, and pegs; everything merges into one print-ready object.
+- **Assemble tool → Auto-fit** — pick one feature on each part, press Auto-fit, nudge with live **Rotate / Offset** sliders, then **Merge parts**.
+
+New assembly modes include **Triangle and triangle** and **Curve and curve**. **Point and point** snaps to vertices at any zoom and has one-click **Coincide points**.
+
+## Where to find it
+
+- Prepare view → **Assemble** tool (toolbar / assembly tools)
+- Right-click a **multi-selection** → **Auto-Fit Assembly** (or equivalent assembly command)
+- Screenshot: `docs/images/assembly.png` (assembly modes, curve-and-curve mate, Auto-fit, Rotate / Offset, Merge parts)
+
+## How to use it
+
+### Auto-Fit Assembly (selection)
+
+1. Select multiple parts that should become one object.
+2. Right-click → **Auto-Fit Assembly**.
+3. Review the result: largest part fixed; others mated by faces / holes / pegs and merged.
+
+### Assemble tool → Auto-fit
+
+1. Open the **Assemble** tool.
+2. Choose an assembly mode (including **Triangle and triangle**, **Curve and curve**, or **Point and point**).
+3. Pick one feature on each part (flat face, circular rim, a single triangle, or a curved patch). For Point and point, use **Coincide points** when you want a one-click snap.
+4. Press **Auto-fit**.
+5. Nudge with the live **Rotate / Offset** sliders.
+6. Press **Merge parts** when the mate looks right.
+
+Rotation is chosen by outline fit **and** a whole-mesh collision check, so pegs seat square without intersecting.
+
+### Related assembly helpers
+
+- **Assemble Separately / Separate** — pull parts out of an assembly in place  
+- **Merge into Single Part** — merge while keeping paint and seam annotations  
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| Poor feature picks | Auto-fit may not find a clean mate — try another mode or feature. |
+| Collision check | Favours mates that do not intersect; adjust Rotate / Offset if needed. |
+| Upstream face-and-face snapping | Edge also carries fixes so face-and-face picking uses the facet under the cursor again. |
+
+For cut-plane joints instead of assembly mates, see [Flexi joints and Cut tool](Flexi-joints).

+# Auto-Fit Assembly
+
+## What it is
+
+**Auto-Fit Assembly** mates a multi-selection into one print-ready object: the largest part stays fixed, the rest mate by matching faces, holes, and pegs, then everything merges.
+
+For feature-pick Auto-fit inside the Assemble tool (Triangle/Curve/Point modes, Rotate / Offset, Merge parts), see [Assemble tool and Auto-fit](Assemble-tool).
+
+## Where to find it
+
+- Object list / Prepare view → select multiple parts → right-click → **Auto-Fit Assembly**
+
+## How to use it
+
+1. Select the parts that should become one object.
+2. Right-click → **Auto-Fit Assembly**.
+3. Check that the largest part stayed fixed and the others seated on faces / holes / pegs.
+4. Slice or continue editing the merged object.
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| Ambiguous geometry | Mating may need the Assemble tool’s feature-pick Auto-fit instead. |
+| Paint / seams | Prefer **Merge into Single Part** when you need annotations preserved — see [Assemble tool](Assemble-tool). |

+# Bake slice to mesh
+
+> Staging: available on `feat/ultra-preferences`. Not on `main` yet.
+
+## What it is
+
+**Bake slice to mesh...** rebuilds the object as the **outer wall the slicer will actually print**, so you can re-slice that mesh at another layer height (or export it).
+
+It uses the current slice’s extrusion paths (including fuzzy skin), not a separate “smooth contour only” path in the live UI.
+
+## Where to find it
+
+- Prepare **object** context menu → **Bake slice to mesh...**
+- Object list object row or canvas right-click on a full object / instance
+
+**Not** on the part menu, multi-selection menus, or Assemble view.
+
+**Enable gate:** exactly one object, and the plate must already be sliced through perimeters (`can_bake_slice_to_mesh` / `slice_bake_available`).
+
+## How to use it
+
+1. Slice the plate so perimeters exist for the object.
+2. Right-click the object → **Bake slice to mesh...**
+3. In the **Bake slice to mesh** dialog:
+   - **Result:** Replace object / Add as new object / Export STL...
+   - **Resolution** (mm)
+   - **Smooth vertical steps**
+   - **Close small gaps** / **Gap radius**
+4. Confirm with **Bake**.
+
+Tooltip: *Rebuild this object as the outer wall the slicer will actually print, so it can be re-sliced at another layer height.*
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| Not sliced yet / no perimeters | Menu item stays disabled. |
+| Multi-object or part selection | Bake is not offered. |
+| Contour vs extrusion UI | Dialog can build contour options, but live UI uses **extrusion paths** (fuzzy skin included). |
+| vs SVG/text gizmo **Bake** | Different feature — gizmo Bake only drops SVG/text editability into an uneditable part. |

+# Compare Slices
+
+## What it is
+
+**Compare Slices** diffs two slices (or sliced files) so you can see what changed between them: **settings**, **time** and **filament** estimates, plus a **per-layer toolpath** comparison.
+
+Use it when you tweak a preset or project and want a clear before/after without guessing from memory.
+
+## Where to find it
+
+- **View** menu → **Compare Slices**
+- Screenshot in the repo: `docs/images/compare-slices.png` (time and filament deltas, changed settings, per-layer toolpath overlay)
+
+## How to use it
+
+1. Produce the first slice (or keep a sliced file you already have).
+2. Change settings or the model as needed and slice again — or pick a second sliced file.
+3. Open **View → Compare Slices**.
+4. Choose the two slices / sliced files to compare.
+5. Review:
+   - which **settings** differ
+   - **time** and **filament** deltas
+   - the **per-layer toolpath** overlay for path-level differences
+6. Use that to decide whether the change is worth keeping, or to document a regression.
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| You only have one slice | You need a second slice or sliced file to compare against. |
+| Large projects | Per-layer overlays can be dense — focus on layers or regions that matter for the change. |
+| Upstream Orca | This is an EdgeSlicer workflow feature; stock Orca does not ship the same Compare Slices window. |
+
+Other notes:
+
+- Comparing a slice to a saved sliced file is useful for “what did this release / preset change?” checks.
+- Pair with [Preferences → Extras](Preferences-Extras) habits (for example Auto-Save) when you want an easy trail of project states to re-open and re-slice.

+# Edge Hub overview
+
+## What it is
+
+**Edge Hub** is the same EdgeSlicer binary run as a **tray-only background process**. It serves the phone page and camera relays. Any slicer window can start it, and it keeps running after you close those windows.
+
+Through the hub you get LAN phone access (QR / token link), optional remote access over Tailscale, printer event notifications, hidden slicer windows for phone-driven slice/send, and the control surfaces that only answer on loopback.
+
+## Where to find it
+
+- System tray → Edge Hub (balloon / menu)
+- Hub page (loopback only) — phone QR, notifications card, window / hidden-instance controls
+- Preferences → Extras → **Phone access** (related options; see [Preferences → Extras](Preferences-Extras))
+
+## How to use it
+
+1. Start EdgeSlicer as usual — a slicer window starts the hub if it is not already running.
+2. Open the hub from the tray when you need the phone QR, notification destinations, or window controls.
+3. Enable **phone access on the LAN**, scan the **QR code**, and use the phone page (`http://<pc>:13640/r/<token>/`) for Streams, Prepare, Devices, and Reprints. Details: [Phone access](Phone-access).
+4. Optionally set up **Tailscale remote access** for HTTPS away from home. Details: [Remote access (Tailscale)](Remote-access-Tailscale).
+5. Configure **notifications** on the hub page’s Notifications card. Details: [Printer event notifications](Printer-notifications).
+6. Let the hub open further slicer windows, including **hidden** ones (no desktop window) so the phone can slice and send without UI on the PC. A hidden instance that would have raised a dialog flags *needs attention* on the hub page and in the tray menu; you can toggle hidden ↔ visible either way.
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| Hub page / tray control plane | Answers only on **loopback** — no tunnel reaches the control plane. |
+| Phone link | Token-gated; survives restarts. **New link** rotates the token and invalidates saved links and home-screen icons. |
+| Firewall (Windows installer) | Adds a rule for **TCP 13640** for the hub. |
+| Closing slicer windows | Hub can keep running in the tray. |

+# Fill bed with copies
+
+## What it is
+
+**Fill bed with copies** packs as many copies of the selection as will fit on the current plate, using a dialog for gaps, margins, rotation, and layout mode.
+
+It fills around objects already on the plate. **Grid** lays an exact regular block; **Compact** packs more tightly (Edge’s compact pack no longer gives up early and leaves empty strips). Filling plate 2 or later puts copies on that plate.
+
+## Where to find it
+
+- Object menu → **Fill bed with copies**  
+- Object menu → **Clone** (`Ctrl+K`) → dialog button **Fill** (tooltip “Fill bed with copies”)  
+
+Entry also sits under Clone in the object menu family described in [Object menu](Object-menu).
+
+## How to use it
+
+1. Select the object (or instance) you want to duplicate across the bed.
+2. Choose **Fill bed with copies**, or open **Clone** and click **Fill**.
+3. In the dialog set:
+   - **Minimum gap between copies**
+   - **Allow rotation** (on/off)
+   - **Layout**: Compact or Grid
+   - **Minimum distance from bed edge**
+   - Optional **Keep the front edge clear** / **Distance from the front edge** (calibration-line margin)
+   - **Ignore support clearance** (staging on `feat/ultra-preferences` — not on `main` yet)
+4. Confirm with **Fill**.
+5. Check the live count / arrangement on the plate, then slice.
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| Objects already on the plate | Fill packs around them. |
+| Grid layout | Exact regular block; hardware validation of Grid is still listed as unchecked by the maintainer — verify the first print. |
+| Ignore support clearance | Staging only — packing can ignore support clearance; warnings may mention support clearance instead of always blaming brim. |
+| Compact layout | Improved vs early bail-out that left empty strips. |
+| Plate 2+ | Copies go on the active / chosen later plate. |

+# Flexi joints and Cut tool
+
+## What it is
+
+EdgeSlicer extends the **Cut tool** so you can join the halves of a cut part with a **print-in-place Flexi joint** instead of a plug: double ring, ball and socket, chain link, hinge (chosen knuckle count, halves can fold shut), screw-top **thread**, or quarter-turn **bayonet** lock.
+
+The cut plane can also bend into a **curved cut**, and flat or curved cuts can remove a **cut thickness** (kerf) so reassembled halves leave room for glue or a joint.
+
+Joints survive saving and reopening a project. The slicer warns when a gap-closing setting would fuse them.
+
+## Where to find it
+
+- Prepare view → **Cut tool** (toolbar / object manipulation)
+- In the Cut tool UI: Flexi joint type and clearance, curved-cut controls, cut thickness / kerf options
+- Assembly-related screenshots: `docs/images/assembly.png` in the repo (assemble modes; Flexi/cut behaviour is in the Cut tool itself)
+
+## How to use it
+
+### Add a Flexi joint on a cut
+
+1. Select the part and open the **Cut tool**.
+2. Place the cut (flat or curved — see below).
+3. Choose a **Flexi joint** instead of a plug: double ring, ball and socket, chain link, hinge, thread, or bayonet.
+4. Set **clearance** and orient the joint to suit the part.
+5. For a **hinge**, set the number of knuckles; the halves can fold shut after printing.
+6. Apply the cut. Keep both halves; connectors (including Flexi joints) sit on the cut surface.
+7. Save the project if you need the joint to persist across sessions.
+
+### Curved cut
+
+1. In the Cut tool, bend the cut plane into a **curved sheet**.
+2. Drag control points; right-click-drag to snap them to the model.
+3. Set density as needed.
+4. Set each half to **Visible**, **Ghost**, or **Hidden** so you can read the result from both sides.
+5. Both halves are always kept. Connectors and Flexi joints sit on the curved surface.
+
+### Cut thickness (kerf)
+
+1. For a flat or curved cut, set a non-zero **cut thickness** to remove a slab of material.
+2. Centre it on, above, or below the cut as needed (glue gap or joint clearance).
+3. Connectors grow to span the gap.
+4. Leave thickness at **zero** (default) for a normal zero-kerf cut.
+
+## Limits / notes
+
+| Situation | What happens |
+|---|---|
+| Gap-closing settings that would fuse the joint | Slicer **warns** — check clearance / related settings before printing. |
+| Project reopen | Flexi joints are preserved with the project. |
+| Hardware validation | Curved cut and Flexi joints (including thread and bayonet) are listed as **not yet printed on hardware by the maintainer** — check the first print carefully. |
+| Zero cut thickness | Behaviour matches a normal cut (no kerf). |
+
+Other notes:
+
+- Prefer Flexi joints when you want print-in-place articulation or a lock without a separate plug.
+- Use cut thickness when glue or joint clearance needs a gap between halves.
