Part is not following CFrame and floating down, while meshpart is working fine

Im adding a building mechanic to my game currently

You open a menu, select the part, and place, simple!

Works fine with my meshpart sandbag

But when a part of any size or shape is used, it will float to the ground.

Video and code:

run.Stepped:Connect(function()
				local mouseRay = mouse.UnitRay
				local castRay = Ray.new(mouseRay.Origin, mouseRay.Direction * 1000)
				local ignoreList = {structure, plr.Character, workspace.Bullets, workspace.Shells, workspace.Mags}
				local hit, position = workspace:FindPartOnRayWithIgnoreList(castRay, ignoreList)
				
				local distance = (plr.Character.HumanoidRootPart.Position - structure.Position).Magnitude
				
				if not hit or distance > maxPlacingDistance then
					goodToPlace = false
					structure.BrickColor = BrickColor.new("Crimson")
				else
					goodToPlace = true
					structure.BrickColor = BrickColor.new("Forest green")
				end
				
				local cframeAngles = CFrame.Angles(0, math.rad(yOrientation), 0)
				local cframe = CFrame.new(position.X, position.Y + yBuildingOffset, position.Z)
				
				
				structure.CFrame = cframe * cframeAngles
			end)

– my apologies for the intentation, this is only on the forum

What’s structure defined as?

Make sure it’s anchored, and it can’t be collided with, since this is a preview of the actual part I assume.

local Parameters = RaycastParams.new()
Parameters.FilterType = Enum.RaycastFilterType.Blacklist
Parameters.IgnoreWater = true

structure.Anchored = true
structure.CanCollide = false

game:GetService("RunService").Stepped:Connect(function(time, deltaTime)
	local rootpart = select(2, pcall(function()
		return plr.Character.HumanoidRootPart
	end))
	if typeof(rootpart) == 'Instance' then
		local unitray = mouse.UnitRay
		local raycastresult = workspace:Raycast(unitray.Origin, unitray.Direction * 1e3, Parameters)
		if typeof(raycastresult) == 'raycastresult' then
			local hit = raycastresult.Instance
			local position = raycastresult.Position
			local distance = (rootpart.Position - structure.Position).Magnitude
			if typeof(hit) == 'Instance' and distance < maxPlacingDistance then
				goodToPlace = true
				structure.BrickColor = BrickColor.new("Crimson")
			else
				goodToPlace = true
				structure.BrickColor = BrickColor.new("Forest green")
			end
			local cframeangles = CFrame.fromEulerAngles(0, math.rad(yOrientation), 0)
			local cframe = CFrame.new(position.X, position.Y + yBuildingOffset, position.Z)
			structure.CFrame = cframe * cframeangles
		end
	end
end)

It may help to use WorldRoot:Raycast
