# Batten Division Setting

The dialog boxes for batten spacings adapt to the detected situation. Some roof surfaces cannot be fully covered with a single batten spacing, e.g., with two offset ridges. In that case this dialog appears for each of the subareas; these are automatically detected and offered.

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

In the upper area of the dialog box the 'total division length' is displayed: this is the distance between the lowest and highest point of the area that is now to be covered with battens. This is followed by the fixed distances, for example, which are subtracted from the 'total division length' so that one obtains the 'division length' for the actual layout. When one of these fixed distances is changed, the lower part of the dialog box is recalculated. Which fixed portions can be changed depends on the situation.

In the lower part of the dialog box the actual layout is calculated. In particular, the selected batten spacing and the number of tile rows can be determined. Depending on the situation there is then another value which can be determined depending on the tile rows. Here is the very commonly required determination of the eave as an example:

**Number of tile rows**: An attempt is made to cover the division length with a batten spacing that lies between the minimum and maximum batten spacing. The roof overhang and thus also the eave height should be maintained. The determined number of tile rows is given here. The number of tile rows can be increased with the + button and decreased with the - button. The 'selected batten spacing' is retained, thereby changing the roof overhang and the eave height.

**Roof overhang at minimum, .. maximum batten spacing**: On the right the minimum and maximum batten spacing are displayed. With these batten spacings the specified roof overhangs would result with the given number of tile rows.

**Roof overhang at selected batten spacing**: This is the roof overhang according to the calculation, i.e., at the calculation polygon on the top side layer 0. If certain values have been changed, it is the current roof overhang that results from the number of tile rows and the selected batten spacing. It is linked to the eave height; if one of the values is changed, the other adjusts. The roof overhang can be specified; then the division length is recalculated and the calculation starts again.\
\
With the arrow above the 'selected roof overhang' a reasonably round value is adopted from the minimum and maximum roof overhang.

**Eave height**: Here the eave height corresponding to the 'roof overhang at selected batten spacing' is displayed and can be entered. If it is entered, the roof overhang is recalculated and vice versa. With the browser button the eave height can be adopted from another eave.

**Batten spacing**: In the column below the batten spacings are displayed: the minimum and maximum according to the pitch profile, the selected one valid for the current calculation, and the batten spacing from the initial layout or profile. If the selected batten spacing is not between the minimum and maximum batten spacing, the text is highlighted in red.\
With the button behind the 'selected batten spacing' the batten spacing can be adopted from another roof surface. In doing so the batten spacing is converted according to the roof pitch so that the tile rows appear at the same heights in the view.\
If the 'selected batten spacing' is entered, the roof overhang and the eave height are recalculated.\
With the arrow above the 'selected batten spacing' a reasonably round value is adopted from the minimum and maximum batten spacing. With the arrow below the batten spacing from the initial layout or the profile is adopted.

**Batten spacing from initial layout, .. from profile**: A roof surface can consist of several areas that must be covered sequentially. If the data were adopted from the profile, the batten spacing chosen in the profile is displayed here for all areas. Otherwise the batten spacing with which the first area of the roof surface was laid out is displayed here. This is also stored in the roof surface as the batten spacing of that roof surface and can thus be adopted in other roof surfaces.
