I know the class reference guide states a "Model" doesn't have a rotation value in the properties. Does anyone know how to rotate it to a certain CFrame angle?
Models are not Parts, they are simply organizational structures. You have to set the CFrames of the Parts inside of a Model to be able to set the Model's Position and Rotation.
Here is a script of mine that will work for you. It should be self-explanatory, but comment on this and I'll clarify what you need.
