Project Setup and Costing Tools
Project setup
- Option 1: Native authoring of IFC in BlenderBIM
- You can find the command in Blender under Scene > IfcProject > Create Project
- Make sure to use IFC4, otherwise convert your IFC2x3 file to IFC4
- Option 2: Importing an .ifc file
- Go to File --> Import --> Industry Foundation Classes
- Navigate to your .ifc file and Click Import
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 selected entity's attributes.
A Cost Schedule has the following attributes you can edit:
- Name,
- Description,
- Identification,
- Status (PLANNED, APPROVED,AGREED,ISSUED,STARTED),
- Submitted On,
- Update Date,
The Cost Schedule's Predefined Type can either be chosen from the dropdown list, or set as "USERDEFINED". If the latter is set as "USERDEFINED", then the attribute Object Type should denote the particular type that further defines the object.
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.
