+Exploring an IFC model
+======================
+
+We're going to load an existing IFC model and explore some common properties
+most users will be interested in.
+
+If you don't have an IFC model available, here's a small one for your
+convenience provided by the Institute for Automation and Applied Informatics
+(IAI) / Karlsruhe Institute of Technology.  It's in German, so you may need to
+use some creativity when reading the data.

+Loading a model

+Blender's interface is divided into panels. The main **Viewport** panel shows 3D
+geometry.  The top right **Outliner** panel shows a tree of geometric objects.
+The bottom right **Properties** panel shows data and relationships.
+
+.. image:: blenderbim-layout.png
+
+The **Properties** panel has tabs to switch between different types of
+properties. Make sure you have the **Scene Properties** tab activated, and find
+the **IFC Project** subpanel. Click on the **Load Project** and browse to your
+``.ifc`` file.
+

+
+After loading, you will see the model appear in the **Viewport** panel.
+
+.. image:: example-project.png
+
+Let's take a look at the **IFC Project** subpanel again. It shows the loaded
+filename, as well as the **IFC Schema**. There are two commonly seen **IFC
+Schema** versions: IFC2X3 and IFC4. Checking the **IFC Schema** is important
+because it has an impact on what BIM data may be stored. IFC4 is the newer
+version and it is recommended to use IFC4 models as it has significantly more
+BIM capabilities compared to IFC2X3. 
+
+.. tip::
+
+   Blender's interface is highly customisable. Panels, panel types, colours,
+   sizes, and tabs may be edited to suit your workflow.
