# Make BaseParts inside out

A very easy way to make parts inside out is to flip their rotation vectors while keeping the others the same. An easy example is using the fromMatrix constructor

```
cframe = CFrame.fromMatrix(
    cframe.Position,
    cframe.XVector,
    -cframe.YVector,
    cframe.ZVector
)
```

This can also be achieved by using the constructor that allows you to set all 12 numbers by hand

Be careful, CFrames that are serialized (sent through remotes or saved in datastores) will be "fixed" to a correctly shaped CFrame and will undo what is effectively a hack
