REGION (C004, C011, C112)

(Rules) (Express)

A region is a volume of space. In modeling systems restricted to surfaces of finite extent, only one region in a model may have infinite extent; all others have finite extent. When more than one region exists in a model, all regions but one have a boundary. For example, a single solid object would require two regions in the model, one for the inside of the object, and one for the outside (which has an infinite extent).
