How do I determine unity "unit" size of a model?
I have purchased some models. When the models are loaded into unity, their scale is reported as 1x1x1, but they take up 2x4x6 units (when I move them around with position). Is there a way to determine how many units a model takes up at runtime, or must I create a big table that says "prefab 1" is 2x4x6, "prefab 2" is 2x2x4, and so on?
I marked tanoshimi's answers correct, but the real answer for me was putting a script on the prefab and then saying:
Vector3 SIZE = GetComponent<$$anonymous$$eshRenderer>().bounds.size;
Note that SIZE will be actual size and include any scaling applied.

"Scale" is a scale factor: 1x1x1 simply means that the object is being rendered in its original scale, not that it occupies only 1x1x1 units.
To determine the volume that a model occupies, you can use mesh.bounds.
