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

When to use it

Use a notch where two parts cross and sit into each other, or for a rebate along an edge. In the fitting workspace the engine adds notches for you where members overlap.

Fields

Field	Unit	Range or options	Default	What it changes
Position X	mm	from 0	1450	Start of the notch along the part.
Angle	°	0.1 to 179.9	Square (90°)	Angle of the notch in the face. Unset means square (90°).
Orientation		start, end	start	Which part end the notch is measured towards.
Length	mm	from 1	100	Distance between the two shoulders, measured square to them.
Depth	mm	from 1	40	How deep the notch goes into the face.
Face		Top, Bottom, Front, Back	Top	The side of the part the processing is on.
Position Y	mm	from 0	Full width	Where a limited notch starts across the face. Unset means full width.
Width	mm	from 1	Full width	Width across the face, as seen square to the part. Unset means full width.

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

Add a notch

1. Select the part in the Parts list.
2. Under Extra processings, click Add.
3. Type notch in the search field and pick Notch.
4. Set Face and Position X. Leave Angle at square unless the notch runs at an angle.
5. Set Length and Depth. Leave Position Y and Width at full width, or set them to limit the notch across the face.
6. Check that the part shows a green check. If not, open the Issues tab.

Caution

Notches with an angle or explicit limits cannot be mirrored or moved to another face. Edit the face and dimensions directly.

Machine export

Format	Status	Details
BTLx	Partly supported	Lap, with bounded rotation in the face and explicit limits.
BVN (Hundegger)	Not written	Refused: operation 0300 failed the shop check.
BVX2 (Hundegger)	Partly supported	Pocket, for plain axis-aligned rectangles only. Skew and explicit limits are left out.

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