Entity Classes
Course (Course) EntityClass 
A bis:PhysicalElement modeling a layer, usually of a single material, whose length greatly exceeds its thickness and often also its width, laid on site on top of another horizontal or nearly horizontal element.

A Course is distinctive from an earthworks element in that a course is a graded granular material (which can be bound or unbound) that is generally processed in some fashion, where as earthworks elements are soil earthen based structure that can be formed by removal and transport of general ground material. Structurally a Course does not have capacity to carry loads over open span, or to be removed or replaced as a single unit.
Courses shall have their Volume stored in their GeometryStream as a Polyface. Further classification of Course instances can be achieved via instances of CourseType. A Course instance can override the Physical Material specified by its corresponding CourseType via its PhysicalMaterial property.
Courses must be contained in PhysicalModels and can be linearly located, typically along an Alignment.
The kind of structure making use of a Course can be also understood via its Category. e.g. A Course instance that is part of a Pavement structure shall use the Domain-ranked cvphys:Pavement category.
Equivalent to IfcCourse.

A Curb is typically a border of stone, concrete or other rigid material formed at the edge of a roadway or footway (Kerb, UK).
Curbs shall have their Volume stored in their GeometryStream as a Polyface. Further classification of Curb instances can be achieved via instances of CurbType. A Curb instance can override the Physical Material specified by its corresponding CurbType via its PhysicalMaterial property.
Curbs must be contained in PhysicalModels and can be linearly located, typically along an Alignment. Instances of Curb, by default, shall use the Domain-ranked cvphys:Curb category.
Equivalent to IfcKerb.
