Hi i’m not sure if is this you want but you can try this
local digSpawn = workspace.Spawn
for i = 1, 100 do
local RandomX = math.random(-digSpawn.Size.X/2,digSpawn.Size.X/2)
local RandomZ = math.random(-digSpawn.Size.Z/2,digSpawn.Size.Z/2)
local RandomSpawn = digSpawn.CFrame * CFrame.new(RandomX,0,RandomZ)
local NewPart = workspace.Part:Clone()
NewPart.CFrame = RandomSpawn
NewPart.Parent = workspace
end
