Oriented housing

An oriented housing is a pocket in a face whose floor can be rotated and tilted, and whose four walls can each lean at their own angle. It follows the BTLx Pocket processing.

When to use it

Use it where a crossing part meets a face at a skew angle and a square notch or mortise would not fit it. In the fitting workspace the engine adds oriented housings for you at crowded joints and skew crossings.

Fields

Veld	Eenheid	Bereik of opties	Standaard	Wat het verandert
Position X	mm	from 0	1500	Where the floor corner sits along the part.
Face		Top, Bottom, Front, Back	Top	The side of the part the processing is on.
Position Y	mm		10	Where the floor corner sits across the face.
Depth	mm		20	How deep the floor corner lies below the face.
Length	mm		100	Distance between the start and end walls, measured square to them.
Width	mm		40	Size across the face, measured square to the front wall.
Rotation	°		0	Turns the housing in the face, from the part axis.
Inclination	°		0	Tilts the floor along its length.
Slope	°		0	Tilts the floor across its width.
Internal angle	°		90	Corner angle of the footprint. 90° gives a rectangle, other values a parallelogram.
Front wall tilt	°		90	Lean of the front wall. 90° is a square wall.
End wall tilt	°		90	Lean of the end wall. 90° is a square wall.
Back wall tilt	°		90	Lean of the back wall. 90° is a square wall.
Start wall tilt	°		90	Lean of the start wall. 90° is a square wall.

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

The rotation angles must stay within 179.9° either way. The internal angle and the four wall tilts must lie between 0.1° and 179.9°.

Add an oriented housing

Select the part in the Parts list.
Under Extra processings, click Add.
Type oriented in the search field and pick Oriented housing.
Set Face, Position X and Position Y for the floor corner, and Depth for how deep it sits.
Set Length and Width. Leave the angles at their defaults for a square housing, or change them to turn, tilt or lean it.
Check that the part shows a green check. If not, open the Issues tab.

3D pockets

A 3D pocket is an oriented housing whose floor tilts both ways, along its length and across it. Pick 3D pocket in the Add list for one with its floor tilted, ready to shape, or tilt any housing yourself.

The card groups the housing the way you measure it. Floor holds Tilt along and Tilt across in degrees, the Start depth at the corner and the Middle depth at the middle of the floor; along and across follow the housing’s own length, so they turn with it, and Make flat levels it again. Turn in the face turns it about its corner. Walls sets how far each wall leans from square to its floor, and whether it is closed or open. Two small sections show the floor and the walls as you change them, and All values opens the plain fields.

You can drag instead, in the drawing and in 3D. The square moves the housing, the round knob past the end wall turns it about its corner, and the arrow from the middle of the floor tilts the floor the way it points, steeper the further you pull. In the view that shows the depth, the knob at the far end of the floor swings the tilt along. Hold Ctrl (Cmd on a Mac) to leave the steps. In 3D the selected housing shows its floor and walls.

Open sides

Under Walls each of the four walls is Closed or Open. An open wall is left out, so the housing runs out to the edge of the part that way: a seat at the edge of a face, or a housing that opens onto the end of the part. The floor always stays, and the top is always open.

A wall that leans out over the floor (a tilt above 90°) is an undercut. A cutter coming straight down onto the floor cannot reach under it, so the part gets a warning: it takes a tilted tool or hand work.

Mirror and move

A housing mirrors in all three planes of the part, exactly: along the part, across its face and onto the opposite face. Its walls, their tilts and whether they are open swap with it, and a parallelogram turns the other way. Mirror it twice and you have the housing you started with.

Moved to a face beside its own, the housing turns a quarter with the part and keeps its distance from the middle of the face. On a square section that is the same housing exactly. On any other section the new face is another width, so check that it still fits.

Machine export

A housing with upright walls and a flat floor goes to BVX and BVN as a plain housing when it is square to the part, and as a turned housing when it is turned in the face. A housing cut right through the part, a floor sloping one way, and a rectangular housing that reaches a part end or runs past the edges of its face go out with a note to check them on the machine. CAMBIUM read their BVN twins in the shop’s September test; the matching BVX forms remove the same wood, but still await their own machine check. A parallelogram stays in the shop test pack. An open side goes out as the closed housing that runs out past the edge of the part, which cuts the same wood.

A 3D pocket needs a five-axis head, such as on a Hundegger ROBOT-Drive or K2, and so does a leaning wall: the card labels them Specialised machine (which machine can cut it). With square, closed walls a 3D pocket goes out at once: BTLx and BTL carry it, BVX writes it as a Pocket turned about all three axes and BVN as operation 0308, each with a note to check the first part until the shop confirms how the machine reads it. A 3D pocket with an open side, and any housing with leaning walls, as members crossing at an angle get, has no form a machine has shown yet: BVX and BVN list it on its part for finishing by hand, and the file is made once you accept the listed omissions. BTLx writes every housing. BTL represents inclined walls and open limits with linked contours derived from the housing geometry, with a receiver warning.

Format	Status	Details
BTLx	Partly supported	Pocket, with every angle, wall tilt and limit. Read back on import.
BVN (Hundegger)	Partly supported	For a pocket with vertical walls and a flat floor: operation 0300 when it is square to the part and clear of both part ends (the part on the face where it runs past one edge), 0305 when it is turned in its face (P7 between -90 and 0). With a note in the file, as CAMBIUM read each of them: one that reaches a part end, one that runs past the edges of its face, one cut through the part, and a floor sloping along the part (0300 with a depth at each end). Experimental, included with a warning unless you leave them out: a parallelogram (0305 with its inner angle). A 3D pocket, a floor tilted both ways with square, closed walls, goes out as operation 0308 with a warning in the file: no machine has shown one of ours yet, and the file cannot be read back into the app as a pocket. Other sloping floors and leaning walls, as members crossing at an angle make, are listed as a machining loss for finishing by hand.
BVX2 (Hundegger)	Partly supported	For a pocket with vertical walls and a flat floor: CAMBIUM's unrotated Pocket when it is square to the part, a turned Pocket (RotationZ between -90 and 0) when it is turned in its face. With a note in the file: a flat rectangle past both face edges or anchored off the face, including a flat rectangular open side closed past the stock; one cut through the part; and a floor sloping along the part (CAMBIUM's sloping Pocket). Each removes the wood CAMBIUM's native conversion does, without controller confirmation of our BVX output. A turned rectangle must stay within the part's length; the separate through-cut and square-at-end restrictions still apply. Experimental, included with a warning unless you leave them out: one sloping across the face (the same Pocket turned a quarter) and a parallelogram (a turned Pocket sheared in its own plane). A 3D pocket, a floor tilted both ways with square, closed walls, goes out as a Pocket turned about all three axes with a warning in the file (no machine has shown one of ours yet) and reads back as the same pocket. A 3D pocket with an open side, other sloping floors and leaning walls, as members crossing at an angle make, are listed as a machining loss for finishing by hand.
BTL 10.6	Supported	039 flat, turned, inclined, sheared, overhanging and through pockets, including end limits. Associated 250 contours preserve tilted walls.
Machine	Specialised machine	A floor tilted both ways, or tilted in a housing turned in its face, and a leaning wall need a five-axis head, such as on a Hundegger ROBOT-Drive or K2. A floor sloping one way, a turned or sheared housing and an open side any machine cuts. Which machine can cut it.

BTL status describes what the specification can represent. CAMBIUM imported our earlier BTL test files; confirmation applies to the tested forms and build. See BTL coverage for representation and receiver caveats.
