Project Setup and Costing Tools

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
