Building a BIM model
Following the project structure set up either manually or with Quick project setup, you can build your model in any way you are used to in Blender. The most common modelling workflows for architecture are:
In the end, all the objects in your model need to be properly parented (ctrl+p), as well as nested, to the correct project spaces - Project, Site, Building and Storey. Whether you do this after you are finished modelling, or already in the course of your work is up to you. It is, however, strongly recommended to adapt it into your workflow and to work with the parent spaces directly for anything but very simple, or existing projects, as it greatly helps managing the complexity of building models.
Any object not attached and nested to a project space parent and collection will be ignored on export.
Classifying Objects
Apart from the correct spatial relation, defined by the project space parenthood and nesting, each object needs to have a proper IFC class. You can set the class of an object either by manually renaming it to "ifcNameOfClass/NameOfObject" or by using the "Assign IFC Class" command provided by the BlenderBIM add-on.
To utilize the "Assign IFC Class" found under Scene > Building Information Modeling > IFC Categorization, you first need to select the object to be changed and select a proper Product, Class and Type from the respective lists. After running the command the object's name is updated and the class is applied.
Any object without an IFC class will be ignored on export.
Exporting to IFC
The correctly set up model can be easily exported as an IFC file with File > Export > Industry Foundation Classes (.ifc/.ifczip).
Currently only selected objects are exported.
