Tenon

A tenon is a tongue on the end of a part that fits into a mortise. The part length includes the tenon.

Tenon. Drawn by the editor's own geometry code.

When to use it

Use a tenon on a rail, stretcher or brace that joins into a post or leg. Put a mortise of the same size on the other part.

Fields

Field	Unit	Range or options	Default	What it changes
End		Start, End	Start	The part end that gets the tenon.
Shoulder (x)	mm	from 0	40	Where the shoulder sits, measured from the chosen end.
Centre Y	mm	from 0	60	Centre line of the tenon across the face.
Height	mm	from 1	40	Height of the tenon.
Width	mm	from 1	Full width	Width of the tenon. Unset means the full width of the part.
Face		Top, Bottom, Front, Back	Back	The side of the part the processing is on.
End shape		Automatic, Square, Round, Rounded, Radius	Automatic	Shape of the tenon ends.
Radius	mm	from 1	Automatic	Corner radius, for end shapes that use one. Shown only for some settings of the other fields.
Length allowance	mm	from 0	No allowance	Hundegger machining allowance. A format without an allowance field, such as BTLx, drops it with a notice.
Width allowance	mm	from 0	No allowance	Hundegger machining allowance. A format without an allowance field, such as BTLx, drops it with a notice.

Default: what Add fills in on a 3000 mm part of 120 x 120 mm.

Add a tenon

1. Select the part in the Parts list.
2. Under Extra processings, click Add.
3. Type tenon in the search field and pick Tenon.
4. Set End, Face, Shoulder (x) and Centre Y.
5. Set Height, and Width if the tenon is narrower than the part. Pick the End shape.
6. Check that the part shows a green check. If not, open the Issues tab.

Caution

BVX does not write tenons; the export lists them for manual finishing. BVN supports a limited set of shapes and no allowances or radius.

Machine export

Format	Status	Details
BTLx	Partly supported	Tenon.
BVN (Hundegger)	Partly supported	Operation 0500, limited shapes. Allowances and radius are not supported.
BVX2 (Hundegger)	Not written	Refused. The tenon is listed as manual finishing.

A file that the app writes is not a check by your machine. See Export for what each format is for.
