door DBL-9070 D1 in wall.W1 at 4' swing right
sill 6"), and drop it once the anchor
spelling lands. Kinds contribute selectors over the jamb pair
(and, where geometry demands, their own placed datums).
Placement: hosted, as the opening interface’s — in wall.W1 at 4'; see
opening for the station vocabulary.
Parameters
| Word | Accepts | Required | Meaning |
|---|---|---|---|
typeDBL-9070 | a doortype | instance · required | the doortype, leading the statement — it fixes or delegates width and height |
inin wall.W1 | a wall | instance · required | the host wall |
atat 4' | length | instance · required | the station along the host, from its start — or from a reference (past / short of), landing to jamb, to jamb.far, or to centerlinethe station’s reference words are their own rows — past, short — and the value is a length along the host, so door.D1.jamb.far + 2' composes here |
pastpast grid.A | plane (normal xy) | instance · optional | the datum the station measures forward from |
shortshort of grid.B | plane (normal xy) | instance · optional | the datum the station measures back from spelled short of: at <length> short of <datum> |
widthwidth 3'-0" | length | bound | the clear width — every door has one; the type fixes it or delegates it (instance) to each placement |
heightheight 7'-0" | length | bound | the clear height — every door has one; the type fixes it or delegates it (instance) to each placement |
u-u-fire-rating "90" | length or boolean or text | bound | job-specific data, one row per name (u-fire-rating): fixed on the type, or delegated (instance <type> [required]) and supplied per placement |
sillsill 3' | length | instance · required · default: the host level + 0’ practice — a hole with no sill is a passage, the commonest opening of all — decision 84; the window refines sill to required with no default (decision 82, D0272) because a 0’ window sill is never intended | the bottom of the opening, up from the host levelsill 3' reads as sill <host level> + 3'; a value below the level is legal (the anchor spelling that writes one is parked — PARKINGLOT “ẑ anchors everywhere”). |
swingswing right | left · right | instance · required · default: right practice — decision 82 left “required?” open; the owner (2026-09-10) left it as the default with no requiredness ruling | the hinge side, in the host wall’s from → to frame |
reverseswing left reverse | flag (the bare word) | instance · required · default: off revit-parity — Flip Hand unchecked | open the other way — the hardware handing (swing left reverse = LHR), a suffix on swing |
Reserved
| Word | Rung | Meaning | Arrives with |
|---|---|---|---|
fire-rating | type | the assembly’s fire rating — drawn, not just scheduled (NCS ships nine fire-rating linetypes) | the duration value type (90 min, 2 hr) — every parameter value carries units; until then the corpus spells it as text, u-fire-rating "90" |
hardware-set | type | the hardware set the leaf carries | the door worksheet — u- today, a built-in candidate then |
head-height (derived) | instance | the head’s height above the level — sill + height (Revit’s Head Height) | the derived-parameter era |
kind | type | which kind of leaf the type is — the category’s declaration lists them | a second kind of leaf — the door’s and the window’s declarations list what is coming (D0242) |
label | instance | what the tag prints when it is not the id | a bubble or tag printing text other than the id — the grid’s bubble is the one that ships |
phase | instance | the phase this element is created in | the phasing era — phases are an ordered list declared in their own file, and a view looks at the model as of one |
demolished | instance | the phase this element is demolished in | the phasing era — phases are an ordered list declared in their own file, and a view looks at the model as of one |
Datums
Inherited from opening:centerline / cl, head, sill, jamb (pair), jamb / jamb.near / jamb.far.
| Datum | Shape | Status | Resolution | Rule |
|---|---|---|---|---|
hinge | plane | core · swinging | operational | The swing-side jamb, by the swing declaration (swing right hinges at the jamb nearer the wall’s to end; left mirrors — the renderer’s rule, now the format’s). Rehang the door and hinge follows to the other jamb, dependents in tow. Default = swing-side jamb; a family may override with a placed datum (pivot doors — the axis really is off the jamb). |
strike | plane | core · swinging | operational | The opposite jamb, same declaration. |
| (sliding/pocket, bi-fold, double) | — | reserved | operational | Each future kind names its own selectors in the spec (fixed/operable side, stack side, active-leaf edge) — never ad hoc. Referencing an absent kind’s selector is a teaching error naming the element’s actual set. |
