How do I rotate a whole model?(UNSANSWERED)

Credit to Anaminus I just annotated(label) it

Any questions comment below

local degreesX=0
local degreesY=90
local degreesZ=0
local model = workspace.Model

function RelativeTransform(center,objects,trans) -- (cframe, table, function)
local new = trans(center) 
for _,object in pairs(objects) do -- get all objects and dose stuff to them
object.CFrame = new:toWorldSpace(center:toObjectSpace(object.CFrame)) -- Changes the position
end
end

RelativeTransform(
model:GetModelCFrame(), -- use the model's center
model:GetChildren(), -- use the model's children
function(center) -- rotate the center by 90 degrees
return center * CFrame.Angles(math.rad(degreesX),math.rad(degreesY),math.rad(degreesZ))
end)

Here is forum that might help though explaining might be more self explanatory as soon as you see the post. Post

ok, first off, you dont need to go to script to just rotate a model. just group it, so it is a model, then rotate it. Dont make things so complex thinking that your a scripter. Your making it harder and longer just to script a rotating model.
