# Tile Layout

During the execution of one of the functions 'Batten / Tiles - Assign' or '.. - Recalculate', the dialog 'Tile layout' always appears at the start of the calculation. It appears once for all selected roof surfaces that have the same tile coverings and batten settings and that lie within the same pitch range of the tile model.

If a profile has been assigned to the house side and the tile covering values in the profile and the roof surface still match, the title displays the note: 'Values from profile position:' followed by the corresponding profile position.

**Tile covering area**: This displays the tile covering used and the detected pitch range.

**Batten division area**: The values of the pitch profile are displayed here and can be edited. The settings made are stored in the roof surface and will be used as the default for the next recalculation.\
For the following values it should be noted that the division of the battens is carried out on the upper side of the layer below the batten layer:

> **Roof batten allowance Z**: This is the distance from the eaves to the lower edge of the wedge batten. A positive value moves the wedge batten out of the roof surface.
>
> **Distance to 1st tile Z1**: This is the distance from the lower edge of the wedge batten to the upper edge of the first batten. This distance determines how far the bottom row of tiles projects beyond the wedge batten.
>
> **Distance to 2nd tile Z2**: For some tile models, e.g. fishscale, the second row of tiles must also be laid at a specific distance. This is indicated here by the distance between the upper edges of the first and second battens. If this distance is 0, there is no special second batten.
>
> **Distance to last tile Zx**: For some tile models, the ridge connection tile has a different batten spacing than the regular tiles. This can be set here. If this distance is 0, there is no special second batten below the ridge.
>
> **Ridge batten distance ZF**: This indicates the distance from the upper edge of the last batten to the ridge line.
>
> **Batten spacing minimum Zi, .. maximum Za**: Most tile models have a certain tolerance for the batten spacing. This is specified here. The batten division attempts to cover the roof surface with a batten spacing that lies between these two dimensions.
>
> **fixed batten spacing**: If the batten spacing should not lie somewhere between the minimum and maximum batten spacing but should be exactly a specific dimension, it is specified here. This is necessary, for example, when roof surfaces with identical batten spacings are to be covered. The browser button next to the input element is particularly helpful here: it allows you to select a roof surface whose batten spacing should be adopted. The batten spacing is even converted to the current roof pitch so that the height of the tile rows is the same in the view.

**Width division area**: The tile widths for division in the direction of the eaves are specified here:

> **minimum .., maximum tile width B**: Some tile models even have a certain tolerance in the direction of their width. This can be specified here. It is only considered for whole tiles during the division; verge tiles and end tiles have fixed widths.
>
> **fixed tile width B**: If there is a tolerance for the tile width, a fixed tile width can again be specified here. It is also possible here to use the browser button to adopt the tile width from an already covered roof surface.
