Roblox Script Change the position of a Model

Changing a position of a Part it's about using Position property.

Doing the same for a Model, is not going to work.

We need to alter the CFrame property instead using a specific method:

workspace.MyModel:SetPrimaryPartCFrame( CFrame.new(0,100,-30) )

If we want to move the model, we can compute the new position with an operation:

local model = workspace.MyModel
local cpos = model.PrimaryPart.Position

wait(5)

local npos = CFrame.new(cpos + Vector3.new(0,0,-100))
model:SetPrimaryPartCFrame( npos )
