# Master data - bricks

In the profile program and the roof layout (structure), tile manufacturers and tile models can be selected for the calculation of tile division. These data are taken from the master database and can be changed or supplemented here.

In the left half there is a tree element in which the entered manufacturers, models and tile types are displayed. By clicking on a plus sign, the corresponding branch of the tree can be opened. Below the tree element are the buttons 'New' and 'Remove'. With 'New' a new element of the same type as the currently selected one can be created. That means, if a manufacturer is selected, a new manufacturer can be created, and so on. With 'Remove' the currently selected element can be deleted. Elements that are below it in the tree structure will be deleted as well.

In the middle of the dialog box there are various input fields:

**Tile model**: As soon as a tile model or a tile is selected, the name of the tile model can be changed here.

**Tile / Roof tile (Identification number)**: The identification number of the selected tile is displayed here and can be changed. Using the button on the right side of the field you can branch into the component catalog and graphically select the desired identification number.

**Identification label**: Each tile can receive a more detailed identification designation in addition to the identification number. This is also displayed when selecting the ridge tile type in the profile or the roof layout, as it is more informative than the identification number.

**Tile function type**: The tile function type determines whether the tile is a whole, a half or, for example, a ridge tile. The tile function types are decisive when covering a profile or roof with tiles. For ridge tiles a separate ridge tile spacing can be entered in the table below. Therefore the ridge tile types are displayed again separately in the field under the input fields.

**Minimum coverage width**: The minimum coverage width is required for the division of a roof surface in the width direction.

**Maximum coverage width**: The maximum coverage width is required for the division of a roof surface in the width direction.

**Lower length LL**: The lower length is the dimension from the lower edge of the tile to the 'lip' with which the tile is hooked onto the batten.

Below the input fields the ridge tile types are displayed again separately because for each ridge tile type a separate ridge batten spacing can be entered in the table for batten spacings.

In the lower area of the dialog box the batten spacings can be entered depending on the roof pitch. Batten spacings that do not exist for individual tile models are simply left blank or given the value zero (0.00). The table has the following columns:

**W**: 'W' stands for angle. In this column the roof pitch is entered from which the following values in the same row apply.

**Z1**: 'Z1' is the eave batten spacing, the distance from the underside of the wedge plank to the top edge of the first batten.

**Z2**: 'Z2' is the distance from the top edge of the first batten to the top edge of the second batten. This particular batten spacing exists only for some tile models.

**ZI**: 'ZI' is the minimum batten spacing for the division of the battens.

**ZA**: 'ZA' is the maximum batten spacing for the division of the battens.

**ZX**: 'ZX' is the distance from the top edge of the penultimate batten to the top edge of the ridge batten. This particular batten spacing exists only for some tile models.

**ZF1 -- ZF5**: 'ZF1' to 'ZF5' are the ridge batten spacings of the different ridge tile types that were defined above. Only one ridge batten spacing is entered for the ridge tile type that actually exists; the remaining fields remain empty.
