Region3 has always wrong rotation

  1. What do you want to achieve?
    I want to get the right rotation for my Region3. Example:

  2. What is the issue?
    The problem is that the Region3 has a false rotation of 90°. Example:

Here is the script to create the Region3:

local Height = 14

MakeRegion = function(Floor)
	local VectorMin =
		(Floor.Position +,Height/2+0.5,0)) + (Floor.Size +,Height,0))/2
	local VectorMax =
		(Floor.Position +,Height/2+0.5,0)) - (Floor.Size +,Height,0))/2

	local Region =, VectorMin)

	local Part ="Part", workspace)
	Part.Size = Region.Size
	Part.CFrame = Region.CFrame
	Part.Anchored = true
	Part.BrickColor = BrickColor.Green()
	Part.CanCollide = false
	Part.Transparency = 0.5
	Part.Name = "ExamplePart"
