How to place parts with fixed rotation

[tahabashar1]

When I place my flower tip model in any place it looks like below in the photos

how do I want it to look like

I have been searching for a solution for that for so long and couldn’t find a way to do that

get the surface cframe of your rayhit using

local surfaceCFrame = CFrame.new(hitPos, hitNormal)

then make sure the flower model’s front face is in the direction you want it to face out
then set the model’s primary part cframe to that

if its a union or mesh just do the same without the primary part, just cframe

[tahabashar1]

local surfaceCFrame = CFrame.new(hitPos, hitNormal)

hitpos is the Mouse.hit but what is hitNormal

[bIorbee]

if you are using a raycast all it is, is result.Normal

normal is a unit vector3

if you arent using a raycast i suggest you do to make it easier to get the normal

[tahabashar1]

local RayCast = workspace:Raycast(RightHand.Position,(Character.RightHand.Position - Position).unit * -50 )
	if RayCast == nil then return end 
	local surfaceCFrame = CFrame.new(RayCast.Position, RayCast.Normal)

	
	local FlowerTip = Assets.FlowerTip:Clone()
	
	PlayerData.GrapplingHook = FlowerTip

	FlowerTip.Parent = workspace

	ChangeCanColide(FlowerTip:GetChildren(),false)

	--FlowerTip:MoveTo(Position)
	FlowerTip:SetPrimaryPartCFrame(surfaceCFrame)

Like this ?

i believe so that would work, it works with my attachments for hit particles

[tahabashar1]

Maybe because It’s not facing the direction I want it to face out, How can I know the front of the model

[tahabashar1]

This is how does it looks like now

[bIorbee]

what is the front face of your model? whatever that is will be in the direction of the surface cframe

by looking at the pictures it looks like the front face is off to the side

[bIorbee]

place a decal inside the model, whatever face it highlights is the front face

[tahabashar1]

no result

[bIorbee]

select the decal then it will show it

[tahabashar1]

didn’t work
but thanks for telling me about the raycast.normal thing because after I searched a lot I found some kind of solution

How do I make a part parallel to the surface it touches?

I am making like blood splatters in my game and each one is simply a flat cylinder . They go in different directions meaning that they touch walls, floors , rooves ect . The problem is they will be at the wrong angle to the surface they touch like this: [image] How do I make it so that when it touches a wall or something it instead looks like this : [image]

How to Use Normal Vector to Align Part to Ramp

The responses in this thread are incorrect. The surface normal is essentially a vector that points directly away from the surface. One easy way of using this data is CFrame.new(part_pos, part_pos + normal). This will cause the object to ‘look at’ the surface normal, thus “aligned” with it. You can simply rotate this CFrame to orient it in whichever way you want relative to the surface. Refer to thread: Explanation of Surface Normal?

Thanks for helping me a little it to understand keywords I should search and Raycast.Normal
