Part collisions in my building system

Help and Feedback Scripting Support
#1

The video above shows my building system. I need help fixing the collisions on my build system. I’ve tried using normals, and I’ve made a little progress on it (as seen in the screenshot below)

Here is my script: (PreviewObject is the green object in the video)

run.RenderStepped:Connect(function(dt)
	if PreviewObject and mouse.Target then
		local GoalPosition = mouse.Hit.Position

		local MyParams = RaycastParams.new()
		MyParams.FilterType = Enum.RaycastFilterType.Include
		MyParams.FilterDescendantsInstances = {mouse.Target}
		
		local PositionResult = workspace:Raycast(cam.CFrame.Position, (mouse.Hit.Position - cam.CFrame.Position).Unit * 1000, MyParams)
		
		if PositionResult then
			GoalPosition += PositionResult.Normal
			print(PositionResult.Normal)
		end

can you send the whole script to a better help?

Yes, but the script above is the only part of the script which determines the position of the part in game, and I’m not sure how the entire script will help

run.RenderStepped:Connect(function(dt)
	if PreviewObject and mouse.Target then
		local GoalPosition = mouse.Hit.Position

		local MyParams = RaycastParams.new()
		MyParams.FilterType = Enum.RaycastFilterType.Include
		MyParams.FilterDescendantsInstances = {mouse.Target}
		
		local PositionResult = workspace:Raycast(cam.CFrame.Position, (mouse.Hit.Position - cam.CFrame.Position).Unit * 1000, MyParams)
		
		if PositionResult then
			GoalPosition += PositionResult.Normal
			print(PositionResult.Normal)
		end
		
		PreviewObject.CFrame *= CFrame.new():Lerp(PreviewObject.CFrame:ToObjectSpace(CFrame.new(RoundVectorToNearestNumber(GoalPosition, BuildingIncrement)) * PreviewObjectRotation), (1 - math.pow(2, -35 * dt)))
		PreviewObject.Color = Color3.fromRGB(94, 255, 83)
		PreviewObject.Transparency = 0.5
		PreviewObject.CanCollide = false
		PreviewObject.CanQuery = false
		PreviewObject.Anchored = true
	end
end)

Edit: The lerp part at the bottom is just a way to make the part smoothly transition to wherever I want it to be at. It sets the CFrame of the PreviewObject to wherever the GoalPosition is
