How to create a point based on other points positions

I am making a node creation system for a project I am working on, and I have tried many methods that have not succeeded fully (only works when nodes are along certain axis). What I would like to do is to make 2 points based on the position of one, i will explain further ahead:

One point that is 4 studs behind the Mid point (where the start is)
One point that is 4 studs infront of the Mid point (where the end is).

Now usually this would be easy, however I want it to work based on other node’s positioning:

From the distance to the green block and Mid, it only affects the Z axis, resulting in the start node only being affected on the Z axis, 4 studs behind the Mid, however, if the Y axis was to change:

Then so would the Y axis, but only based on where it is.

EXAMPLE
Lets say that the distance in between the green point and mid was 16, on the Z, and 16 on the Y also, 0 on the X, if I want the point to be 4 studs behind / Infront/ the difference, the Start would end up on (0, 12, 12), however, the outcome of the end part is based on the Node infront of it too:

Hi Sam, I remember you from YouTube. I’ve been working on improving on your engine, and I may have a solution for this. It isn’t too optimized but it should work for your old system that you had on YouTube. Here is the code. You can change the -2 and 2 to the number of studs you want the path offsetted by.

for Index, Part in pairs(workspace.items.nodes:GetChildren()) do
	local node1 = workspace.items.nodes:FindFirstChild(Part.Name-1)
	local node2 = Part
	local node3 = workspace.items.nodes:FindFirstChild(Part.Name+1)
	
	if node1 and node3 then
		local Middle = Instance.new("Part", node2)
		local End = Instance.new("Part", node2)
		
		Middle.Name = "middle"
		Middle.CanCollide = false
		--Middle.Transparency = 1
		Middle.Size = Vector3.new(0.5,0.5,0.5)
		Middle.Anchored = true
		Middle.CFrame = CFrame.lookAt(node2.Position, Vector3.new(node3.Position.X, node2.Position.Y, node3.Position.Z))
		
		End.Name = "end"
		End.CanCollide = false
		--End.Transparency = 1
		End.Size = Vector3.new(0.5,0.5,0.5)
		End.Anchored = true
		End.CFrame = Middle.CFrame * CFrame.new(0,0,-2)
		node2.CFrame = node2.CFrame * CFrame.new(0,0,2)
	end
end

This does the old node system that you had. I also have a question that you may be able to answer.

All of my turns are fine until there is a turn that is a different direction. The enemy partially does the turn then teleports into the correct position onto the path. I made sure that all of the code is good, but I just cannot seem to figure it out.
