Stopping structures from clipping with build system

[sweetboss151]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I want the spawnpoint to not clip into any parts when the mouse is on the surface

2. What is the issue? Include screenshots / videos if possible!
   This SpawnPoint thing keeps clipping into the floor
   

   
   
   

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   My code:

local function SnapToGrid(position: Vector3)
    local gridStep = 1
    return Vector3.new(
        math.round(position.X / gridStep) * gridStep,
        math.round(position.Y / gridStep) * gridStep,
        math.round(position.Z / gridStep) * gridStep
    )
end

UserInputService.InputChanged:Connect(function(inputObject)
            if inputObject.UserInputType ~= Enum.UserInputType.MouseMovement then
                return
            end

            local mousePosition = UserInputService:GetMouseLocation()
            local rayParams = RaycastParams.new()
            rayParams.FilterType = Enum.RaycastFilterType.Exclude
            rayParams.FilterDescendantsInstances = { spawnClone, player.Character :: any }
            local rayResult = MouseRay(mousePosition, rayParams)

            if not rayResult then
                return
            end

            local _, boundingBoxSize = spawnClone:GetBoundingBox()

            local mousePos = rayResult.Position
            local surfaceVector = rayResult.Normal
            local endPos = mousePos + (surfaceVector * boundingBoxSize / 2)

            local gridPosition = SnapToGrid(endPos)
            spawnClone:PivotTo(CFrame.new(gridPosition))
end)
