What other way could I do the same thing?

So to get right to the point, there is a built-in Roblox Function, GetModelCFrame and my question is if there is another way of doing the same this by hand (Because of it being Deprecated)?

I am not trying to request a script just wondering about this function!

Every model has a property called "PrimaryPart". This part is what's used when positioning a model with MoveTo and SetPrimaryPartCFrame. Model.PrimaryPart.CFrame is the same thing as GetModelCFrame.
