Walls and openings

Pick a build-up, draw a line, and get a layered wall from one level to the next. Doors and windows are hosted in it: each one cuts through every layer, and each step passes the walls on, so every opening so far stays cut.

Component	What it’s for
Wall types	A wall build-up: pick an Australian preset (brick veneer, double brick, timber stud, CLT, AAC and more) or type your own layers in millimetres.
Walls	Layered walls along any line, polyline, arc or outline, from one level to the next, joined at the corners, with plan linework at the cut height.
Doors	Doors hosted in your walls (swing, double, sliding, pocket, bifold), cut through every layer, with frames, leaves, plan swings and elevation marks.
Windows	Windows hosted the same way (fixed, casement, awning, hopper, sliding, double hung) at a sill height, with frames, sashes, glass and drawing symbols.
Curtain wall	Mullions, transoms and glass along a straight, curved or closed path between levels, in box, I, T, round, fin or flat bar profiles, with optional trusses behind.

Wall types

wall_types A wall build-up: pick an Australian preset (brick veneer, double brick, timber stud, CLT, AAC and more) or type your own layers in millimetres. Cost: Free.

Inputs

Input	Type	On the component	Default	What it does
`preset`	Text	Dropdown	`brick veneer`	a common Australian build-up, or custom (from layers). One of `brick veneer`, `double brick`, `timber stud`, `steel stud partition`, `concrete 200`, `precast 150`, `blockwork 190`, `CLT`, `rendered AAC`, `custom`
`name`	Text	Text field	blank	type name (blank: the preset’s)
`layers`	list of Text	Text field	blank	layers exterior -> interior, thickness in mm: ‘brick 110; cavity 40; timber stud 90; plasterboard 10’ ( = core). Replaces the preset’s layers when given
`plane`	Plane	Wire	—	where the swatch sits (default: world origin)
`save`	Boolean	Button	—	add this type to the Alien library

Outputs

Output	Type	What it gives you
`wall_type`	Text	wall_type record for walls
`names`	list of Text	layer names, exterior first
`materials`	list of Text	layer materials
`thicknesses`	list of Number	layer thicknesses (m)
`total`	Number	overall thickness (m)
`swatch`	list of Brep	a stepped section sample, one solid per layer
`colours`	list of Colour	colour per swatch solid
`info`	Text	what happened: a summary, sources and notes

How it works

Layers run exterior -> interior in mm (‘brick 110; cavity 40; timber stud 90*; plasterboard 10’; m and cm work; * marks the core); a layers text replaces the preset’s.
Junk tokens are reported one by one; an empty custom falls back to a generic 200 mm wall.
Outputs layer names, materials, thicknesses, the total and a stepped swatch with colours.

Walls

walls Layered walls along any line, polyline, arc or outline, from one level to the next, joined at the corners, with plan linework at the cut height. Cost: Free.

Inputs

Input	Type	On the component	Default	What it does
`path`	list of Curve	Select in Rhino	—	wall location lines: lines, polylines, arcs, splines, closed outlines (a sample room when unwired)
`wall_type`	list of Data	Wire	—	wall_types record(s), one per path (the last repeats; default: generic 200 mm)
`levels`	list of Data	Wire	—	level records (sample levels when unwired)
`base`	Text	Text field	blank	base level: name, code or index (blank: the first)
`top`	Text	Text field	blank	top level: name, code or index (blank: the level above the base)
`height`	Number	Slider 0–30	`0`	height (m); 0 = up to the top level
`offset`	Number	Slider -5–5	`0`	base offset from the base level (m)
`location`	Text	Dropdown	`centre`	which line of the wall the path is. One of `centre`, `exterior`, `interior`, `core centre`
`flip`	Boolean	Switch	off	swap the exterior and interior sides
`join`	Boolean	Switch	on	clean joins: mitre L corners, trim walls that butt into others
`cut`	Number	Slider 0–3	`1`	plan cut height above the base level (m)
`site`	Data	Wire	—	site record (optional): places the sample room

Outputs

Output	Type	What it gives you
`walls`	list of Text	wall records (for doors and windows)
`solids`	list of Brep	one solid per layer per wall
`materials`	list of Text	material per solid
`colours`	list of Colour	colour per solid
`plan`	list of Curve	plan linework at the cut height: every layer boundary and the wall ends
`centrelines`	list of Curve	centre of each wall’s thickness, at its base
`info`	Text	what happened: a summary, sources and notes

How it works

The exterior is on the left of an open path; closed outlines put it outside; flip swaps.
Location line: centre, exterior, interior or core centre.
Corners within a wall are mitred exactly; with join on, walls meeting end to end are mitred (L) and walls stopping inside another are trimmed to its face (T). Crossings (X) are left overlapping.
Layers that fold over on bends too tight for the wall are dropped with a note.
Plan linework is cut at a height above the base (default 1 m).

Doors

doors Doors hosted in your walls (swing, double, sliding, pocket, bifold), cut through every layer, with frames, leaves, plan swings and elevation marks. Cost: Free.

Inputs

`walls`	list of Text	wall records with every opening so far (wire into windows)
`solids`	list of Brep	the walls’ layer solids with every opening cut
`colours`	list of Colour	colour per solid

`info`	Text	what happened: a summary, sources and notes

How it works

Positions ‘1.2, -1, 50%’ (negative = back from the end), or points (nearest wall); wall by id, index, list or ‘all’.
Openings stay clear of corners and wall ends and never overlap (skipped or moved with a note).
walls in, walls out: each record gains its openings, so walls -> doors -> windows chains, and solids are the walls with every opening so far cut (straight walls rebuilt face by face, curved ones by Booleans).
hand is seen from the side the door opens into; swing in or out.
Drawings: plan (leaf drawn open with its swing arc), reflected (seen from below), elevation (dashed V to the hinges).
design: generated geometry (e.g. object_3d’s parts) is fitted into each leaf, mirrored for right hands.
