# Automatic Bar Width

## Automatic member width

Sometimes it is necessary to create a panel above a window or a door that is to extend from the lintel to the top of wall. Such panels are entered via the lintel-bolt input, but an identification number for a panel is used. In this case, the panel width does not need to be calculated; instead, the width can be specified as 99 m. For this value, the HRB interpreter calculates the width of the panel from the starting point to the layer contour at the top of wall. In this case, the starting point is the window lintel. This could, for example, look as follows:

<figure><img src="/files/7b0a4682874dd6683139a3458d288c7a96d90179" alt=""><figcaption></figcaption></figure>

The panel then extends from the outer edge of the left window jamb to the outer edge of the right window jamb, and in height from the underside of the lintel bolt to the top of wall.

Small optimization of the setting: if the cross-section rotation is set to 90° and, instead of the cross-section width, the cross-section thickness is set to 99 m, the panel's local coordinate system is also optimized.

### Module panels

On certain bolt-frame stations, complete window and door replacements or the corner post assembly can be inserted into the wall as a finished construction. These so-called modules are prefabricated and inserted into the wall in one piece at the bolt-frame station. For this to be possible, the construction must be transferred to the machine marked as a module. The wall postprocessor can do this automatically if there is a panel in the wall to which the material-dependent function 'defined module' is assigned in the wall postprocessor. This panel must be wide and high enough for its outline in the wall view to enclose all members that are to be part of the module.

In the image below, the panel is wide enough to extend from the left edge of the left window jamb to the right edge of the right window jamb, and vertically from the underside of the sill to the underside of the top plate. It does not matter whether the panel also overlaps the sill and top plate, since only the members that lie completely within the outline of the module panel are taken into account.

So that the module panel is automatically generated appropriately by the HRB module, we make the following setting for the lintel bolt:

<figure><img src="/files/44d7449117ba8d95ea6afe707b71c9d46c4b6a2b" alt=""><figcaption></figcaption></figure>

* Identification number: Any identification number configured in the wall postprocessor for the generation of modules.
* Cross-section width: 99 m for automatic calculation of the width up to the top layer contour at the top of wall.
* Cross-section thickness: any thickness
* Organizational group: any group that is not yet used for other components.
* Layer: any layer. The recommendation is a layer that is not used for other components, so that the layer contours for the module panel can be adjusted as required.
* X offset: set the overhangs on the left and right using fixed values or variables. Here, the variable for the window jamb width was used.
* Y offset: any depth position. Here, the panel was shifted centrally into layer 0.
* Reference edge: opening edge. Since we define the panel via the lintel bolt, this is the layer edge at the top of opening.
* Offset: OSTHUkW. This is the system variable for the height of the lintel from the underside of wall. This shifts the starting position of the panel from the top of window to the underside of wall.

The panel now starts at the underside of wall and is automatically limited in height (cross-section width) at the next layer edge. Since this would, especially for windows, be the layer edge at the underside of opening from the underside of wall, the panel would only extend from the underside of wall to the underside of window. To prevent the layer edge at the underside of window from interfering, we move this layer edge below the wall with an offset of -1.0 m. See the image below:
