Visualisation Limitations

Visualisations are based on the same model as that used for the calculations but you may notice some slight differences in the way the model is displayed vis-a-vis the floor constructions and Zone volume calculation options.

1. DesignBuilder uses a single floor 'slab' for each block even when some floors in the block may have different constructions. This is done for simplicity and also to ensure the most realistic images are produced without step changes in the floor level throughout the block. So there is only limited scope for adjusting the height of floor level in the visualisation.
2. Where there is external floor and internal floor in the same block you will notice that the internal floor slab used to represent the floor in the rendered view is the same no matter what settings are used in the Zone volume options. You will also notice that the floor slab takes on the texture of the internal floor even for areas of the floor that are actually external floor and may have a different texture.
3. Where the Ground floor construction is below ground and is not subtracted from zone volume option is selected, the top of the ground floor will be shown in the visualisation screen as being at ground level - this is consistent with the data. However you will not be able to see the ground construction below the ground if you adjust the camera level to be below ground.
