Today I needed to make a part rotate by 90 degrees, so heres the math:

```
local rotated = CFrame.Angles(0,math.rad((90)),0) * H.CFrame
```

rotated is what I am going to rotate it to, only problem is that it goes like to a whole other position instead of just rotating, and even though this is so simple I have no idea why.

When I actually rotate it this is what I do:

```
local rotated = CFrame.Angles(0,math.rad((90)),0) * H.CFrame -- cframe
local rotatedBack = H.CFrame
print(rotated)
print(rotatedBack)
there[H.Name] = tweenService:Create(H,doorOpenInfo,{CFrame = rotated}) -- rotate it
```

From printing rotated and rotatedBack (the og cframe) the position part is changed so idk whats going on.
