Model not rotating as a unit?

I'm trying to make the entire model spin from a center point (which in this case I've labeled as spin.)

The tree of models is "SecurityCamera" -> "SecurityParts" AND "Spin"(Part) -> Script

The script is located under "Spin".

Not sure how to use "SetPrimaryPartCFrame", but I just know that's what you do for this situation.

Code -

local Main = script.Parent
while true do
	Main.SetPrimaryPartCFrame = script.Parent.SetPrimaryPartCFrame * CFrame.fromEulerAnglesXYZ(-.25,0,0)
	wait(0.01)
end

Make sure the model has its PrimaryPart declared (click on the Model in Explorer and look at the Properties window -- if PrimaryPart's value is empty, you need to define it (click on the empty value, your cursor will change, then click on the central part of your model).

The problem with your script is that you're trying to multiply a function "SetPrimaryPartCFrame" and a CFrame. Also, when calling functions, you need to use ":", not "." . Instead, do:

Main:SetPrimaryPartCFrame = Main:GetPrimaryPartCFrame() * CFrame.fromEulerAnglesXYZ(-.25,0,0)

Note the GetPrimaryPartCFrame() call after the '='. The logic of this line is "Set the cframe to whatever the current cframe is multiplied by this other CFrame"

Hi!

I believe you mixed up "SetPrimaryPartCFrame" with "PrimaryPart". SetPrimaryPartCFrame is a void function, while PrimaryPart is the property.

There is a different, more recommended method made by TigerCaptain (I credit him for this script!) This is a function that find all the baseparts in the model that follows the offset in unity with the PrimaryPart. This script will use ToObjectSpace() that converts world coordinates to object coordinates, to find the offset between any part and the PrimaryPart. The model MUST have a PrimaryPart otherwise this will not work.

I suggest you examine the script to learn along the way.

local Main = script.Parent

local function tweenModel(model)
	if not model.PrimaryPart then return end --If the model doesn't have a PrimaryPart then end.
	local details = {}
	local function getParts(par, t) --The function to get all the parts inside the model
		local t = t or {}
		for i,v in pairs(par:GetChildren()) do --For every child in the model do
			if v:IsA("BasePart") then --The object is a basepart
				t[#t+1]=v
			else
		t = getParts(v, t) --getParts is the variable for all baseparts within the model.
			end end
		return t
	end
	for i,part in pairs(getParts(model)) do
		if part ~= model.PrimaryPart then --The basepart is not the PrimaryPart
			details[part] = model.PrimaryPart.CFrame:toObjectSpace(part.CFrame) --Transforms CFrame from world to object coordinates. This is the offset.
		end end
	local con = model.PrimaryPart.Changed:connect(function()
		for part,offset in pairs(details) do
			part.CFrame = model.PrimaryPart.CFrame*offset --All the surrounding parts will the follow the PrimaryPart's offset.
	end end)
	while wait() do --This is where you can change the PrimaryPart and the other parts will follow.
	Main.PrimaryPart.CFrame = Main.PrimaryPart.CFrame * CFrame.fromEulerAnglesXYZ(-.25,0,0) --Play the rotation method.
	end
end

tweenModel(Main) --Play the function, Main is the model.
