Levels and grids

Levels and grids come first. Wire Site base into both, and every wall, slab, stair and beam afterwards knows where it sits.

Component	What it’s for
Levels	A stack of named levels (basements, storeys, roof) with RLs from the site datum, level lines and heads for elevations, and plan labels.
Grids	Column grids the way Revit and ArchiCAD draw them: numbers one way, letters the other, from bay sizes, with bubbles, intersections and dimensions.

Levels

levels A stack of named levels (basements, storeys, roof) with RLs from the site datum, level lines and heads for elevations, and plan labels. Cost: Free.

Inputs

Input	Type	On the component	Default	What it does
`count`	Integer	Slider 1–100	`4`	storeys from the ground up
`height`	Number	Slider 0.5–20	`3.2`	floor-to-floor height (m)
`heights`	list of Text	Text field	—	per-storey heights (m), from the lowest up, e.g. ‘4.5, 3, , 3.6’ (a blank keeps height)
`base`	Number	Slider -20–50	`0`	ground level above the site origin (m)
`outline`	Curve	Select in Rhino	—	floor plate to copy to every storey (optional; else the site boundary or a 20 x 12 m sample)
`site`	Data	Wire	—	site record from bim_site: places the levels, datum gives RLs, scale sizes the text
`naming`	Text	Dropdown	`Level 1`	level names. One of `Level 1`, `L1`, `L01`, `Level 01`, `LVL 1`, `custom`
`prefix`	Text	Text field	`Floor #`	custom names: prefix + number, or # for the number (‘Floor #’, ‘##F’ gives 01F)
`start`	Integer	Slider -5–100	`1`	number of the first numbered level
`ground`	Text	Dropdown	`Ground`	name of the ground level. One of `Ground`, `Ground Floor`, `GF`, `G`, `numbered`
`basements`	Integer	Slider 0–10	`0`	storeys below ground (Basement 1 is just below)
`roof_level`	Boolean	Switch	on	add a Roof level on top of the last storey
`view`	Text	Dropdown	`both`	level lines for which elevations. One of `front (along X)`, `side (along Y)`, `both`
`ends`	Text	Dropdown	`right`	level heads at. One of `right`, `left`, `both`, `none`
`margin`	Number	Slider 0–20	`2`	level lines run past the floor plates (m)
`scale`	Text	Dropdown	`site`	drawing scale of the annotation. One of `site`, `1:50`, `1:100`, `1:200`, `1:500`
`text`	Number	Slider 1–10	`3.5`	text height on paper (mm) at the drawing scale

Outputs

Output	Type	What it gives you
`planes`	list of Plane	one per storey
`elevations`	list of Number	storey z (m)
`floor_heights`	list of Number	floor-to-floor of each storey (m)
`names`	list of Text	storey names
`plates`	list of Curve	floor plate at each storey
`roof`	Plane	top of the last storey
`total`	Number	ground to roof (m)
`levels`	list of Text	level records, storeys and roof: wire into the building components’ levels input
`lines`	list of Curve	level lines for elevations and sections
`heads`	list of Curve	level heads: datum symbol, name and RL at the line ends
`annotations`	list of Curve	plan label on each level: ‘LEVEL 1 RL +3.200’
`labels`	list of Text	one per level
`rl`	list of Number	reduced level of each level (m): datum + elevation
`info`	Text	what happened: a summary, sources and notes

How it works

count, height and per-storey heights (‘4.5, 3, , 3.6’; a blank keeps the default); basements below the ground level; an optional Roof level.
Naming: Level 1 | L1 | L01 | Level 01 | LVL 1 | custom (‘Floor #’, ‘##F’), a ground name and a start number.
RL = site datum + elevation (‘RL 23.460’ with an AHD datum, else ‘RL +3.200’).
Level lines run along project X and/or Y past the plates by margin; heads at either or both ends.
The old outputs (planes, elevations, floor_heights, names, plates, roof, total) stay one per storey; levels, lines, heads, annotations, labels and rl include the roof.

Grids

grids Column grids the way Revit and ArchiCAD draw them: numbers one way, letters the other, from bay sizes, with bubbles, intersections and dimensions. Cost: Free.

Inputs

Input	Type	On the component	Default	What it does
`site`	Data	Wire	—	site record from bim_site: grids start at its origin and run along its rotation
`x_spacing`	Text	Text field	`3x7.2`	bays along project X (m): ‘7.2, 7.2, 8.4’ or ‘3x7.2’; empty = no grids that way
`y_spacing`	Text	Text field	`2x6`	bays along project Y (m)
`labels`	Text	Dropdown	`numbers along X`	numbered or lettered grids along X (the other way gets the other). One of `numbers along X`, `letters along X`
`x_start`	Text	Text field	`1`	first label of the grids along X (‘1’, ‘4’, ‘C’, ‘X1’)
`y_start`	Text	Text field	`A`	first label of the grids along Y
`skip_io`	Boolean	Switch	on	skip I and O in letters (they read as 1 and 0)
`extension`	Number	Slider 0–20	`3`	grid lines run past the outermost grids (m)
`bubble`	Number	Slider 4–30	`10`	head diameter on paper (mm) at the drawing scale
`ends`	Text	Dropdown	`both`	heads at. One of `both`, `start`, `end`, `none`
`scale`	Text	Dropdown	`site`	drawing scale of the heads and dimensions. One of `site`, `1:50`, `1:100`, `1:200`, `1:500`
`custom`	list of Curve	Select in Rhino	—	extra grids: angled or curved curves (optional)
`custom_names`	list of Text	Text field	—	names of the custom grids (default G1, G2 …)
`dimensions`	Boolean	Switch	on	bay and overall dimension strings (mm) on the start sides

Outputs

Output	Type	What it gives you
`grids`	list of Text	grid records: wire into the building components’ grids input
`lines`	list of Curve	grid lines
`heads`	list of Curve	bubbles: circle and name
`names`	list of Text	one per grid line
`points`	list of Point3d	grid intersections
`point_names`	list of Text	’A/1’ …
`dims`	list of Curve	dimension linework
`info`	Text	what happened: a summary, sources and notes

How it works

Bays as ‘7.2, 7.2, 8.4’ or ‘3x7.2’ (values over 100 read as mm); numbers along X and letters along Y by default (swap with labels), start labels such as ‘4’, ‘C’, ‘X1’; I and O skipped; AA after Z.
Heads (bubbles) at both, start, end or no ends, sized in paper mm at the drawing scale.
Custom angled or curved grids with names; their crossings are found on the curve.
Bay and overall dimensions in mm on the start sides.
