It’s kind of hard to explain but I am making an NPC that scans a certain area using raycast. I’m not sure what is going on here but when it is pointing completely in the direction of one axis it makes a perfect rectangle shape but when I rotate it the shape is distorted. I have a video:

Here is how I did the scanning:

```
local function rotateVector(v, angle, axis)
local radians = math.rad(angle)
local rotationCFrame = CFrame.fromAxisAngle(axis, radians)
return rotationCFrame:VectorToWorldSpace(v)
end
for i = 0, 70, 1 do
for k = 1, 20 ,1 do
local newDirection = rotateVector(mainDirection,35 - i,Vector3.new(0,1,0))
newDirection = rotateVector(newDirection,10-k,Vector3.new(1,0,0))
local raycast = workspace:Raycast(character.LookPart.Position,newDirection * 1000)
if raycast then
local dot = SS.Dot:Clone()
dot.Position = raycast.Position
dot.Parent = workspace.Testing
local newBeam = LidarBeamTemplate:Clone()
newBeam.Attachment1 = dot.Attachment
newBeam.Parent = dot
DebrisService:AddItem(dot,1)
end
end
RS.Heartbeat:Wait()
end
```

I’m not sure how to fix this, could anyone help me? I am not familiar with vectoring.
