A Level is a named height reference for building elements. Set Ground floor at 0 mm for this example. The Level itself does not create a floor slab.
- Open your project and select Levels in the left tool strip. Dravit switches to Front in 2D. The dashed Project Zero line marks the fixed 0 mm reference; the Level selector still says No levels.
