In many situations, specific end connections or bar end treatments are automatically generated at the ends of entered bars. Which connections or treatments should be generated and how they appear can be specified in this menu area. The following end treatments and connections are available:

**Trimming:** With trimming, the bars are connected to the connecting bars in such a way that they adapt to their shape. This can result in butt connections but also in notches or relief notches.

**Chamfer:** The bars receive a chamfer with the set chamfer angle.

**2** **Chamfers:** The bars receive two chamfers. The first chamfer is defined by the chamfer angle and the face length. The face length can alternatively be entered as a percentage instead of an absolute value. This percentage refers to the height of the respective bar. As a result, the actual height of the face can vary. The second chamfer can be defined by an angle, the inclined length, and the base length. Enter the value to be used. The previous value will be deleted automatically.

**Concave profile:** The bars receive a concave head profile. All values can alternatively be entered as percentages. These percentages refer to the height of the respective bar. Consequently, the actual dimension of the affected value may differ for different bars.

**Convex profile:** The bars receive a convex head profile. All values can alternatively be entered as percentages. These percentages refer to the height of the respective bar. Consequently, the actual dimension of the affected value may differ for different bars.

**Tenon:** Connection with a through tenon. For the connection to the bar end of a mating bar, a rebate allowance can be set. This is considered automatically only when the connected bar terminates at the end of another bar.

**Stepped tenon:** For the stepped tenon, two step dimensions can be entered in addition to the through tenon.

**Tenon with bore:** In addition to the configuration options of the stepped tenon, there are various options for the bores. The tenons can be provided with one or two bores. The position of the bores depends on whether one or two bores are specified. A single bore can be placed automatically so that it is centered on the tenon or on the bar axis. Two bores can be placed using a single value (edge distance) or their positions can be distributed evenly over the tenon (thirding). The bore in the mortise can be offset relative to the bore in the tenon (bore offset). Using the countersink depth, the entire bar with the tenon can be recessed into the bar with the mortise by the entered amount.

**Dovetail tenon:** The width of the dovetail tenon should be matched to the tool used. The same applies to the flank angle. The backcut does not shorten the tenon but deepens the dovetail mortise.

**Offset:** Offsets can be created in different forms. For easier selection, the numbers of the face offsets from the drop-down list have been inserted in the auxiliary image.

**Offset with tenon:** The face offset with tenon combines the configuration options of the tenon with those of the offset.

**Ridge board:** For very shallow roof pitches, it can be useful to shorten the ridge board. To do so, you can enter a limiting angle and an angle for the board shortening. If the limiting angle G becomes smaller than the specified value, the ridge board is automatically shortened to the entered angle W.

**Decorative collar:** The decorative collar is a special overlapping type. The board thickness can alternatively be halved or set to a fixed value. The fixed value applies to the bar whose end is being connected. The decorative collar can also optionally be provided with one or two bores. Two bores can be placed using a single value (edge distance) or their positions can be distributed evenly over the tenon (thirding).
