Mapping/Entities/misc model
Models
To add a model right click on any 2D view window to bring up the Context menu. Choosing 'Create model' will open the 'Model Selector' screen. These folders contain all models (*.md2 or *.md3 files) available, but not all of them are usefull for maps. The map models are in the Template:Path directory (if you are using a working copy of the repository) or the Template:Path pk3-file (if you are using an installer).
With the model selected, open the 'Entities' tab in the sidebar. RMB 
onto the properties window will open the dialog window. This way you can add or remove properties for the model.
The spawnflags property is used to set levelflags for the model. Note that models with no levelflags set do not appear at all (whereas brushes with no levelflags set will be shown on every level).
