Mortise. Drawn by the editor's own geometry code; right: the carved part in 3D.

When to use it

Use a mortise on the part that receives a tenon, such as a leg that takes a rail. The tenon goes on the end of the other part.

Fields

Field	Unit	Range or options	Default	What it changes
Position X	mm	from 0	1460	Position of the housing along the part.
Centre Y	mm	from 0	60	Centre line of the housing across the face.
Length	mm	from 1	80	Length of the housing along the part.
Width	mm	from 1	40	Width of the housing across the face.
Depth	mm	from 1	40	How deep the housing goes.
Face		Top, Bottom, Front, Back	Front	The side of the part the processing is on.
End shape		Automatic, Square, Round, Rounded, Radius	Automatic	Shape of the housing 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.
Depth 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 mortise

1. Select the part in the Parts list.
2. Under Extra processings, click Add.
3. Type mortise in the search field and pick Mortise.
4. Set Face, then Position X and Centre Y to place the housing.
5. Set Length, Width and Depth to the size of the tenon.
6. Check that the part shows a green check. If not, open the Issues tab.

Tip

Size the mortise from the tenon on the other part, so both use the same length, width and depth. The trestle bench example shows matching pairs.
