BlenderBIM Add-on/BlenderBIM Costing

Please remove this "BlenderBIM_Addon_Documentation" template.

Introduction

Each Project using BIM needs to be set up with the proper structure. BlenderBIM uses the open data structure of IFC. As with almost everything with BlenderBIM, you can do that either manually from Blender itself, or use the specialized commands provided by the add-on. The default folder is prepackaged with the IFC4 schema and you can download different schema from the buildingSMART website. However, unless you are an IFC guru, you shouldn’t have to touch this.

Project setup

- Option 1: Native authoring of IFC in BlenderBIM You can find the command in Blender under Scene > Building Information Modeling > System Setup. 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.

- Option 2: Importing an .ifc file
