How to make model not collide with part?

[x8yv (apollo)]

Hey, I’m making a simulator game and I want to figure out how to make a tool not collide with part?
The tool looks like this:

I’m using the handle to detect when it touches a part so it can give money to the player.
I have a area name system that uses parts and I want it so the handle (or the tool) doesn’t collide with it even if it’s CanCollide option is off.
Also I have an unlock area system which also uses parts. How can I make it so the airplane tool doesnt collide with that? Thanks for any help.

Script in paper airplane: (If it helps)

local tool = script.Parent
local plr 
local ClonedTool = game.ReplicatedStorage.PaperAirplane:Clone()
local Player = game:GetService("Players")
local Handle = script.Parent.Handle
tool.Bounce.OnServerEvent:Connect(function(player, event)
	plr = player
	print(player)
	local mouse = player:GetMouse()
	local ball = tool.Handle
	tool.Parent = workspace
	ball.CFrame = tool.Handle.CFrame
	ball.CFrame = CFrame.new(ball.Position, event)

	local BV = Instance.new("BodyVelocity", ball);
	BV.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
	BV.Velocity = ball.CFrame.lookVector * 50 -- how fast it throws
	wait(.1)
	tool.Handle.BodyVelocity:Destroy()
	
	local Camera = workspace.Camera
	Camera.CameraType = Enum.CameraType.Scriptable
	Camera.CameraSubject = tool
end)

local isTouched=false

script.Parent.Handle.Touched:Connect(function(hit)

	print("hit")

	if hit.Parent:FindFirstChild("Part") then
		print("Is part")
		wait(2)
		script.Parent:Destroy()
		
		local ClonedTool = game.ReplicatedStorage.PaperAirplane:Clone()

		ClonedTool.Parent = plr.Backpack

		print("Destroyed")
		
		plr.leaderstats.Coins.Value += 20
		game.Workspace.Coins:Play()
		
	end
end)

script.Parent.Handle.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Part") then
		hit.CanCollide = false
		wait(2)
		hit.CanCollide = true
	end
end)

Heres a little drawing of what my problem is:

(Sorry for my amazing drawing skills!)

You only need to use CollisionGroups

[pumpkyrofl (Pumpky)]

PhysicsService can do it
loop through every children in the plane and make the collision group a part called “100robuxarea”, make the part collide with the same group too.

[Dede_4242]

What he needs is very easy, you set the paper airplane’s CollisionGroup to a custom one, he sets the Model‘s CollisionGroup as the same and make the CollisionGroup not collide with itself but collide with the normal CollisionGroup

[DasKairo (Cairo)]

To add on to this, you need to create it with PhysicsService

love PhysicsService = game:GetService("PhysicsService")

PhysicsService:RegisterCollisionGroup("Group")
PhysicsService:GetCollisionGroupCollidable("Group", "Group", false)

You need to Register a CollisionGroup if you want it to be functional at all.

[Dede_4242]

From what I know you don’t have to, there’s the CollisionGroup thing in the Model tab if I’m not wrong, can’t you configure it from there?

[DasKairo (Cairo)]

The CollisionGroup Property is only available in BaseParts, not Models.

Edit: misread.

My airplane is still colliding with the parts after I’ve done this.

[Dede_4242]

Yes, but in the Studio, if you got to the Model Tab, here’s a thing under Advanced if I’m not wrong where you can configure CollisionGroups, I created a CollisionGroup from there and I had the option to choose with ehich CollisionGroup it would collide

[Dede_4242]

Try going in the Model Tab, under Advanced, there should be a button that says:
CollisionGroups
Click there and you should be able to configure everything

Both of these solutions worked, Just had to fix something up. Thanks for the help!
