# Sheathing and Cladding - Settings

A setting defines the covering with boarding and paneling for one layer of a roof surface. Classic boardings (exposed boarding, tongue-and-groove, profile C, etc.) or other types of coverings such as panels (OSB, DWD), insulation boards, insulating material (Isofloc), foils, etc. can be generated. These can then be output in material lists.

The dialog box for defining the setting has two states: initially it is presented with one column for defining a boarding. Using the function '1 >> 3' it can be expanded to 3 columns. Then, within one setting, different coverings can be specified for all surface areas of a layer (eaves, finished, unfinished) in each column.

The first two entries apply to all columns:

**Name:** Enter the name of the setting here.

**Storage measurement:** The surface areas are initially determined using the eaves function, e.g., the eaves area ends exactly at the exterior wall edge. If this is covered with boarding, the boarding can change the surface area; for example, the boarding may extend not only to the exterior wall edge but to the next rafter. Therefore, the surface areas resulting from the boarding differ from those from the eaves function. Both surface areas remain available, and it can be specified here which of the two surface areas should be saved for the measurement. This can be set separately for each layer and then applies to all surface areas of that layer.

The further entries then apply separately for each column:

**Apply to:** This defines in which surface area of the layer the covering of this column should be applied. 'V' stands for eaves area, 'A' for finished area and 'N' for unfinished area. The areas are covered starting from the eaves area and can only be covered in contiguous sections. Thus one can cover V+A or V+A+N, but not V+N. These rules are also clarified by automatic locking of the switches.\
The areas are covered in the order V - A - N. If V is covered, the boarding may shift the boundary to A. Covering A does not shift the boundary back but starts at the shifted boundary.

**Identification number:** Identification number for the material of the covering. For DICAM users there is no restriction on the types of components used.

**Designation:** For the components of the covering, a member type and a designation can also be specified.

**Thickness:** This is the cross-sectional dimension that corresponds to the panel thickness for a panel or the member width for a beam (squared timber). This is oriented perpendicular to the roof surface in the covering.\
If the thickness was specified in the identification number, it cannot be changed here.

**Width:** This is the cross-sectional dimension that corresponds to the panel width for a panel or the member height for a beam (squared timber). This lies on the roof surface in the covering and corresponds to the cover width (see also note: cover width/board width).\
If the width was specified in the identification number, it is adopted but can be changed here.

**Method**: There are two methods by which the paneling can be generated:\
Boarding boards: Using this method, boarding boards are generated and placed with the set length and the settings for longitudinal joints.

> Continuous: Using this method, specially profiled panels are generated:
>
> ▪ The panels are laid in horizontal rows from the left or from the right. Laying begins with the lowest row.
>
> ▪ An attempt is made to start the next panel row with the leftover piece of the previous panel.
>
> ▪ The horizontal dimension of the first panel can be used to influence the distribution.
>
> ▪ Profiled panels are automatically considered with their cover surface in the covering. It is not necessary to enter a negative gap to cover the tongue with the groove.
>
> ▪ At the left and right roof ends as well as at vertical and inclined opening edges, the panels are automatically trimmed around the profiling so that a smooth panel edge is created.
>
> ▪ For the automatic covering, limit values are entered in the component catalog. The values apply in roof surfaces analogously to walls:
>
> ▪ Minimum width at wall end: Minimum dimension of the panel at the wall end measured from the wall end in the longitudinal direction of the wall.
>
> ▪ Minimum width at opening edge: Minimum dimension of the panel at the vertical or inclined opening edge measured from the opening edge in the longitudinal direction of the wall.
>
> ▪ Minimum joint distance between panel rows: Avoidance of cross joints. Minimum distance between the panel joints of two vertically adjacent panel rows measured in the longitudinal direction of the wall.
>
> ▪ Minimum joint distance to opening edge: Minimum distance between panel joints and opening corners measured in the longitudinal direction of the wall.
>
> ▪ For each value there is a minimum and a reduced minimum value: For the automatic covering, the system first attempts to comply with the minimum value. If this is not possible, the limit is reduced down to the "reduced minimum value".
>
> ▪ In the covering the "tool width for panel splitting" is set. If the leftover panel is processed further elsewhere, it must be shortened by this processing width.

**Width 1st board B1:** This is the width of the first board at the horizontal edge where the covering begins. For example, with tongue-and-groove boards the groove of the first board is cut off because that board edge remains visible. The first board then therefore has a different cover width. If this is specified as 0.0, the first board receives the same width as the other boards.

**Length L:** If only one board length is processed, it can be specified here. This length is only used if no stock lengths are used. If this length is 0.0 and no stock lengths are used, the boards are generated as long as the roof surface.

**Use stock lengths:** This sets whether the stock lengths currently available should be used in the covering (see also: Boarding\_StockLengths).

**Longitudinal joints:** Depending on the option chosen in the 'Method' field, various options are available here:\
**Boarding boards method**: If a length is specified or stock lengths are used, a single board length often does not cover the entire surface to be covered. The boards must be joined, creating longitudinal joints. If the 'free' option is used, the full length of the board is always used and then the next board follows. If the 'on rafter' option is used, the board is shortened to the last rafter on which it rests. The next board then adjoins there. With 'free' one therefore only gets a leftover piece at the last board of a board row, whereas with 'on rafter' typically each board has such an adjustment (see also: Boarding\_Optimization).

> **Continuous method:**
>
> ▪ In the case of "staggered", the longitudinal joints are taken into account according to the limits defined on the panel.
>
> ▪ The option "Field staggered" first considers 2 conditions: each panel should rest on at least 2 rafters and longitudinal joints of adjacent panel rows must not be located in the same rafter field. Then the limit values are additionally considered.\
> For panelings in layers 0 to -7 the rafters are searched for in the same layer or below. For panelings in layers 1 to 7 the rafters are searched for in the same layer or above.

**Laying angle**: For the 'continuous' method you can set the laying angle of the panels here.

**Front side of the panel toward**: For panels with different sides (e.g., different qualities on front and back) you can specify which side of the roof surface the front side of the panel should face. The good (higher-quality) side of the panel is considered the front side.

**Distribution direction from**: Should the distribution of the paneling proceed from the left or right side of the roof surface?

**Tool width for panel splitting**: For the 'continuous' method, the leftover of a panel is used to start the next row again. Depending on how the panel is cut, there is a cut gap of greater or lesser width by which the panel width must be reduced.

**Boarding boundaries:** The covering initially orients itself to the area boundaries from the eaves function. When covering the finished and unfinished area (boarding areas 2 and 3) there is only orientation to these area boundaries. For covering the eaves area (boarding area 1) and the combinations of eaves area with finished area, the covering can also be 'rafter-oriented' or 'wall-oriented'.

> Rafter-oriented boarding boundaries: First the boarding is generated up to the area boundaries. Then the board ends are extended beyond the area boundaries to the next rafter. It is also considered that a board must have at least 2 supports (rafters, ridge or valley rafters); thus, if necessary, it is extended to the second rafter after the area boundary.
>
> Nearest-rafter boarding boundaries: The boarding starts at the boarding boundaries of the eaves area. Then it is extended into the finished area up to the next rafter. The boarding is also extended if it already rests on 2 or more rafters. If after extension the boarding rests on only one rafter, it is extended once more to the next rafter.
>
> Wall-oriented boarding boundaries: First the boarding is generated up to the area boundaries. Then the board ends are extended beyond the area boundaries to the corresponding wall edge. In doing so, how many supports the board has is not considered.

**Rafter / wall overhang:** If the boarding boundaries are rafter-oriented or wall-oriented, the exact boundary is defined here: it can be set to the center, rear edge, or with a value a boarding overhang.

**Rafters divide paneling:** In the case that the paneling is not rafter-oriented, it can be selected whether the rafters should divide the paneling. This is the typical setting for insulation between rafters: first the finished area is fully covered with insulation, which is then divided by the rafters. This creates the corresponding strips of insulation.\
If the paneling is not divided by the rafters, conversely it can generate machining (eaves boarding notches etc.) into the rafters.

**End A:** Here it is set whether the individual boarding boards are cut off at their end along the respective boundary or cut perpendicular on their longest length.

**Cut at area boundaries G:** This setting only affects the parts of the panelings that abut horizontal area boundaries. In some cases a single board must then be cut out according to the boundary; it then ends exactly at the boundary. In other cases, for example often with over-roof insulation, the board or panel should remain whole and instead the area boundary should be shifted (into the unfinished area). On the one hand the panel then does not need to be cut unnecessarily, and on the other hand the additionally covered area can be considered and billed in the measurement.

### **Note:** Cover width/board width:

For boards with tongue-and-groove or rebate the cover width is smaller than the material width. For covering with boarding the cover width must be specified so that the correct number and length of boards can be determined.\
In the material order, however, the actual material width must be specified. The following options are suitable for this:

> 1.) The width of the boards is entered directly into the identification and order number; thus a correct order is ensured without further processing.
>
> 2.) In post-processing of the material list, mark the affected rows and correct the 'Width' column in one step. If the boards are of component type 'panel', this also calculates the panel area in the material list from the actually consumed material. The covered area is correspondingly smaller.

### **Note:** Boarding optimization:

In each board strip (boards lying consecutively in the longitudinal direction) the combination of available lengths that produces the least waste is automatically determined. One or multiple stock lengths can be considered.

If the longitudinal joints of the boarding boards must be on the rafters, which is the normal case, manual determination of the waste by hand would be very difficult.

The optimization takes into account that a board must rest on at least 2 supports (rafters, ridge or valley rafters).
