Window cutter parts overlapping

[pienter2 (Mango)]

so im trying to do a script that makes a hole in a wall and the window can fit into that hole. The problem is that my script works fine for one window but if i try to run it with second window the parts overlap on each other. I have no idea how to run the function so that the parts dont overlap.

local function config(wC)
	wC[1].Name = "wC"
	wC[2].Name = "wC"
	wC[3].Name = "wC"
	wC[4].Name = "wC"
	local up = wC[1]
	local down = wC[2]
	local left = wC[3]
	local right = wC[4]
	
	return up,down,left,right

	
end




function create.resPos(wC, win, canv)
	
	local up, down, left, right = config(wC)
	local distanceX = canv.Size.X - win.Size.X
	local distanceY = canv.Size.Y - win.Size.Y
	local offSetX =   win.CFrame.X - canv.CFrame.X 
	local offSetY =	  win.CFrame.Y - canv.CFrame.Y
	
	
	up.Size = Vector3.new(canv.Size.X - distanceX, math.clamp(distanceY / 2 - offSetY,0,canv.Size.Y), canv.Size.Z)
	up.CFrame =  canv.CFrame * CFrame.new(offSetX, canv.Size.Y / 2 - up.Size.Y / 2, 0) 
	
	down.Size = Vector3.new((canv.Size.X-distanceX),math.clamp(distanceY / 2 + offSetY,0,canv.Size.Y),canv.Size.Z)
	down.CFrame = canv.CFrame * CFrame.new(offSetX,-canv.Size.Y/2+down.Size.Y/2,0)
	
	left.Size = Vector3.new(math.clamp((distanceX/2)+offSetX,0,canv.Size.X),canv.Size.Y,canv.Size.Z)
	left.CFrame = canv.CFrame * CFrame.new(-canv.Size.X / 2 - -left.Size.X / 2,0,0) 
	
	right.Size = Vector3.new(math.clamp((distanceX/2)-offSetX,0,canv.Size.X),canv.Size.Y,canv.Size.Z)
	right.CFrame = canv.CFrame * CFrame.new(canv.Size.X / 2 - right.Size.X / 2,0,0)
	
	
	if right.Size.X<0.06 then
		local OverlapForumula = math.clamp((((canv.Size.X/2)-canv.Size.X - math.abs(offSetX)) + (win.Size.Z/2)),0,500)
		



		up.CFrame = up.CFrame * CFrame.new(-OverlapForumula/2,0,0)
		up.Size = Vector3.new((up.Size.X-OverlapForumula)+0.07,up.Size.Y,up.Size.Z)
		down.CFrame = down.CFrame * CFrame.new(-OverlapForumula/2,0,0)
		down.Size = Vector3.new((down.Size.X-OverlapForumula)+0.07,down.Size.Y,down.Size.Z)
	end


	if left.Size.X<0.06 then
		local OverlapForumula = math.clamp((((canv.Size.X/2)-canv.Size.X - math.abs(offSetX)) + (win.Size.Z/2)),0,500)
		



		up.CFrame = up.CFrame * CFrame.new(OverlapForumula/2,0,0)
		up.Size = Vector3.new((up.Size.X-OverlapForumula)+0.07,up.Size.Y,up.Size.Z)
		down.CFrame = down.CFrame * CFrame.new(OverlapForumula/2,0,0)
		down.Size = Vector3.new((down.Size.X-OverlapForumula)+0.07,down.Size.Y,down.Size.Z)
	end
	return up,down,left, right
end

i did it myself by checking parts overlapping after creating them all.
