# Beveled Edges at Upper Connections

Claddings at upper connections and wall ends are cut perpendicular to the layer edge up to and including version 18.02. Bars parallel to these locations retain their rectangular cross-section; they were not chamfered. Since version 19.01 it is possible to specify the cut angle. Especially for thicker materials such as insulation boards and cross-laminated timber, the cut must also be executed on the board. Corner posts at right-angled wall corners and purlins at the roof connection can be chamfered accordingly. The resulting machining operations on boards and bars are transmitted to the controlled machines accordingly.

* HRB editor: In the upper connections and layer penetrations of the corners a column with identifiers for the cut angle at the layer edge has been added:

&#x20;

* R stands for *perpendicular* and corresponds to the previous section
* A stands for *adjusted* and yields a cut angle parallel to the roof surface or to the adjacent wall.
* W stands for *angle bisecting* and yields a cut angle bisecting the angle with the roof surface or the adjacent wall.
* In doing so, cladding is first always generated perpendicular to the layer edge. Any additional cut is then always executed into the material from that point; the cladding is therefore not extended.

&#x20;

* The sections / chamfers are generated only on lines with W or A:

&#x20;

* If bars (e.g., purlins at a wall corner) terminate in a layer whose layer edge remains perpendicular (R), the bars are connected according to the input order. If the layer edge is to be angle-bisecting (W) or adapted (A), the bar end is cut accordingly. The length is determined by the penetration.
* Chamfers on studs are always executed along the entire stud length, even if the wall edge ends earlier.

&#x20;

* This identifier is then also present at the layer edge. If a manually entered panel is reduced by the layer edge, the corresponding section angle is also executed at that layer edge.
