This will create a basic spatial tree. It will create a tree of collections with the structure IfcProject > IfcSite > IfcBuilding > IfcStorey This is merely for convenience instead of having to create it all by yourself, since all IFC exports require a valid spatial tree. You can see the tree of collections in the outliner when this is done.

Creating a Cost Schedule

Entity Definition of IfcCostSchedule An IfcCostSchedule brings together instances of IfcCostItem either for the purpose of identifying purely cost information as in an estimate for constructions costs or for including cost information within another presentation form such as a work order.

You can find the command in Blender under Scene Properties > IFC Cost Schedules Panel > "+ Add Cost Schedule".

Editing attributes

Whenever the greasepencil button is present, this enables editing the entitie's attributes. A Cost Schedule has the following attributes you can edit: Name

Creating Cost Items

Entity Definition of IfcCostItem An IfcCostItem describes a cost or financial value together with descriptive information that describes its context in a form that enables it to be used within a cost schedule. An IfcCostItem can be used to represent the cost of goods and services, the execution of works by a process, lifecycle cost and more.
