General

The studs in a wall can be interrupted by window and door openings. The studs are initially limited by the layer contour of the opening. In addition, in the studs located within the area of an opening, further operations (drillings and clearances) may be created. These result from the settings for the corresponding window or door type. If a wall contains openings with a type for which no setting is defined, the studs are cut at the layer contour of the opening. Studs that are not completely separated by the opening receive a clearance.

The studs are not necessarily bounded exactly by the layer contour of the opening. The studs have a distance 'Side clearance' to the side opening edge. The distance above and below is determined by the values 'Top clearance' and 'Bottom clearance', respectively.

If a stud meets the side of an opening along its full height, the stud receives a section there.

If a stud does not meet the side of an opening along its full height, it is checked whether the vertical distance between the operation and the bottom or top side of the stud is greater than the value 'minimum cross-sectional height'. If the value is greater, a clearance is generated in the stud. If the value is smaller, the further procedure depends on the setting in the drop-down list 'Separate stud'.

If the option 'Yes' is selected here, the stud receives a separating cut at the right and left edges of the opening. This produces three segments, one of which lies within the opening. At the height of the lower or upper opening edge, a longitudinal separating cut is created in the segment that lies within the opening. The value from the field 'Slot width' is used for the tool width.

If the option 'No' is selected in the drop-down list 'Separate stud', no operation is generated in the stud. The stud is therefore not separated.

If the option 'Slot' is selected here, the stud is also not separated, but a limited groove is created in the stud. The value 'Slot width' is used for the width of the limited groove and the value 'Slot depth' is used for the depth.

Slanted opening edges

For window and door openings, opening edges that are not vertical or horizontal are treated separately.

Initially, only those studs receive a section here that meet a line of the opening's layer contour along their full height. If one or more lines end in a stud, the stud does not receive an operation here.

For window and door openings (door and window slanted, pointed) that are slanted only at the top, the value 'Top clearance' is considered on those sides. For window openings that are slanted at both top and bottom (diamond window), the value 'Side clearance' is considered on all sides.

Rounded opening edges

For door openings that are rounded at the top (arched door), the value 'Top clearance' is considered. In this case, for studs that are cut by the arch on the top and bottom sides, a drilling with the diameter of the arch is generated. Additionally, for each of these studs a section is also generated. The section runs through the points where the arc intersects the top and bottom of the stud.

If the arch ends within a stud (transition between straight and arc), a section and a drilling are generated in the stud.

For window openings that are entirely rounded (round window), the value 'Side clearance' is considered.

Drillings

In addition to the openings, drill rows can also be generated at the openings. The drill rows are always vertical regardless of the shape of the opening. The drill row always extends from the lowest to the highest point of the opening. For non-vertical opening edges, the Z value of the upper and lower points is used. The value 'minimum length allowance' specifies how far the drill row is extended upward and downward. In all studs that are then touched by the drill row, a continuous vertical drilling is always generated. This applies even if the drill row ends within a stud. The 'Distance of the drilling to the opening' is always measured horizontally. The distance is measured to the opening edge and not to the stud end.

At the beginning and end of the drill row a countersink drilling can additionally be generated. The depth is specified in the field 'Depth' and the diameter for the countersink drilling is specified in the field 'Diameter'.

The input fields

For the situation around door and window openings, you can save as many settings as desired, which can be accessed with the drop-down lists. With the browser button to the right of the drop-down lists you can switch to the settings dialog box for these configurations and change the settings or create new ones.

Top clearance: The window cutout is enlarged upward by this value.

Bottom clearance: The window cutout is enlarged downward by this value.

Side clearance: The window cutout is enlarged to the right and left by this value.

Minimum cross-sectional height: The value indicates how large the cross-section above and below the opening must be at minimum. If the value is zero, the next three fields are deactivated. If the remaining height of the stud is less than the value in this field, the procedure set in the drop-down list 'Separate stud' is followed.

Separate stud: Here you set what happens to the stud in the area of the opening when the value entered in the field 'minimum cross-sectional height' is undershot. (see here)

Slot width: The value specifies the width of the slot that is produced in the stud at the upper and lower edge of the window. The value must always be greater than zero.

Slot depth: The value specifies the depth of the slot that is produced in the stud at the upper and lower edge of the window. The value must always be greater than zero.

Depth of the groove: In the studs that end at the lateral opening edges with a section having base and tilt angle 90°, a clearance can still be generated. For studs that end with an inclined section (tilt angle ≠ 90°), no clearance is generated. The value specifies the depth of the groove that is produced in the studs to the right and left of the opening. If the value is zero, no groove is generated.

Width of the groove: The value specifies the width of the groove that is produced in the studs to the right and left of the opening. If the value is zero, no groove is generated.

Distance to the opening: If the value is greater than zero, a drilling is generated next to the opening. In the affected studs a continuous drilling (depth = 0) is always generated. See also: Drillings.

Diameter: The value specifies the diameter of the drillings next to the opening. If the value is zero, no drilling is generated.

Minimum length allowance: The drillings are extended upward and downward by at least this value beyond the opening. Even if the value is zero, continuous drillings are generated in all affected studs (except the 'additional drillings').

Ident number: Here the identification number for the fasteners belonging to the drillings is entered.

Countersink drilling diameter: The value specifies the diameter of the additional drilling. If the value is zero, these drillings are not generated.

Countersink drilling depth: This value specifies the depth of the countersink drilling. If the value is zero, these drillings are not generated.
