# How to design a bent sheet metal bracket and get its flat pattern with solidcraft

Repo: [tangency-labs/solidcraft](https://github.com/tangency-labs/solidcraft) | Difficulty: Advanced | Time: 1 hour 30 minutes | Basis: From the README

Use flanges, hems and fold/unfold to model a bracket, then read out the flat pattern for cutting.

**Who it is for:** Small fabricator or hobbyist ordering laser-cut and bent metal parts

**The problem:** A shop wants a flat pattern and you only have a 3D idea of the bent part.

**The outcome:** A bent sheet metal model with a flat pattern you can send to a cutting service.

## Steps

1. Open the app and sketch the base profile.
2. Add flanges and hems using the sheet metal features.
3. Unfold the part to get the flat pattern.
4. Export the flat pattern in a supported format.

## Prompt to paste into your agent

```text
Using SolidCraft's sheet metal features, outline how to model <bracket description> with flanges and get a flat pattern. Verify bend allowances against what my fabricator expects before I order.
```

## Caveat

Early software: confirm the flat pattern dimensions against your fabricator's bend rules before cutting any metal.
