Does all the model uploaded here are based on each regions standards?

Hi Guys,

I am a new member here, I have work on a several substation as-built modeling (Pointcloud to 3d model) in Revit to be specific. Now one of my client is asking the model to be done in autocadd, In revit, I normally model from scratch, I know some of you find it a bit of a drag to model from scratch when you can have a libraries of model where you can insert anytime, but revit does not have a generic model specifically for substations to begin with. That is why I am eager to know if all substation model components differ in each regions in terms of ( height, width, type of materials etc,). My back ground is in architecture and had a little knowledge in electrical so please bear with me, And does any of you uses a specific Autocadd plug in for substation modeling?

I would really appreciate if you can give me an idea of how the models and these components work.
