Quad Filler is a lightweight Blender add-on that helps you quickly patch holes and connect open edge chains with clean results. Select two open edge chains, run the tool, and it generates a quad-first bridge automatically — reducing manual bridging, cleanup, and topology fiddling.

Quick Demos

Patch missing areas faster and keep your modeling flow moving.

✨ What’s New in 1.0 ✨

The Beta tool is now a full release with expanded bridging modes and a more flexible workflow.

Edge-Count Bridging Modes (Open Edge Chains)

Quad Filler 1.0 supports multiple edge-count combinations so you can patch a wider range of real-world modeling holes. Results are designed to be quad-first, with minimal cleanup.

5 edges → 3 edges

All quads

4 edges → 2 edges

All quads

4 edges → 1 edge

Quads + 1 n-gon (5-sided face)

3 edges → 2 edges

Quads + 1 triangle

3 edges → 1 edge

Quads + 1 triangle

2 edges → 1 edge

Quads + 1 triangle

Equal edge-count bridging (1-to-1 type)

N edges → N edges (N = 1 ~ 49)

All quads

Important limitation

Closed loops are not supported (open edge chains only).

Hotkey Friendly + Shortcut Recording

Assign a shortcut and keep it in muscle memory. You can also click the key field to record a new shortcut — the same experience as Blender’s official Keymap editor.

Use it like a quick “patch tool” while modeling: select the two edge chains, trigger the hotkey, continue working.

Clean Results, Minimal Cleanup

Quad Filler focuses on producing a clean, readable topology flow that’s easy to edit. For mixed cases (triangle / n-gon), the output is still designed to keep surfaces stable and easy to refine.

How to Use

Simple workflow: select two open edge chains and run Quad Filler.

Compatibility

Quad Filler supports Blender 3.4 – 5.0 (Edit Mode · Edge Select).

Known Limitations

• Open edge chains only — closed loops are not supported.
• Highly irregular topology can produce unexpected results (like any automatic bridging tool).
• In some cases, face normals may point the wrong way. If that happens, use Blender’s native normal tools (e.g., Flip / Recalculate Outside) to correct the affected faces.

Refund Policy

If the add-on cannot run properly on your system and we can’t reasonably fix it, you are entitled to a full refund within 30 days of purchase.
