View

view plan L1-plan of level.L1 scale 1/4" cut 4'-0" name "L1 Floor Plan"

Project nothing and are projected off by nothing: a view is a declared query (kind, level, scale, cut, range, crop) over the elements above, never a container of them. of <level> is a dependency edge onto a datum, and the crop’s corners (from (x, y) to (x, y) — the view’s placement slot; Revit’s crop region) are ordinary coordinates whose datum references are edges too; a corner never anchors to a wall. The view range (decision 74; revit-parity: View Range) is three viewtype facts — top / bottom / depth, lengths relative to the level, defaulted by the query (top = the level’s top, bottom = the level, depth = bottom) — and what a plan shows is classified against it: cut / above / beyond / not drawn, computed per element, never authored; openings follow their host. Inverted relationships (bottom above cut, top below cut, depth above bottom) are errors with the fix written out, not a dialog. The annotation body is reserved; rcp / section / elevation are reserved kinds. Placement: the query’s target — of level.L1 for a plan; at grid.B to grid.A for a section or elevation, with an axis word when no grid in the stations implies it. The crop, from (x, y) to (x, y), is ordinary coordinates.

Parameters

Word	Accepts	Required	Meaning
`type` `A-PLAN`	a viewtype or `plan` · `section` · `elevation`	instance · required	a viewtype, or a bare kind word for an untyped view — the kind is the language’s, never a template’s name
`of` `of level.L1`	a level	instance · required · plans only	the level a plan looks at
`from` `from (0', 0') to (40', 30')`	line (direction z)	instance · optional · plans only	the crop — `from (x, y) to (x, y)`, lower-left to upper-right (Revit’s crop region); ordinary coordinates, never anchored to a wall
`axis` `vertical`	`vertical` · `horizontal`	instance · optional · sections only	which way the plane runs — written bare before `at`; inferred from a grid in the stations when unwritten (D0267 when neither)
`at` `at grid.B`	plane (normal x) or plane (normal y)	instance · required · sections only	the cut plane’s station — on the axis the plane is normal to
`to` `to grid.A`	plane (normal x) or plane (normal y)	instance · required · sections only	the far clip’s station — the pair’s order is the gaze
`scale` `scale 1/4"`	length	either · required · default: 1/8” practice — decision 76(a) — the language default a view falls to when neither it nor its viewtype writes one	paper inches per model foot — the sheet scale
`cut` `cut 4'-0"`	length	either · required · default: 4’-0” · plans only revit-parity — View Range: Cut plane, Associated Level + 4’-0”	the cut plane’s height above the level
`top` `top 8'-0"`	length or a level ± offset	either plans: required · default: the level’s top sections: optional revit-parity — View Range: Top — the level’s story is where a plan stops looking up	the range top above the level on a section or elevation, an optional level trim (`top level.L3 + 2'`) with no default
`bottom` `bottom 0'`	length or a level ± offset	either plans: required · default: the level + 0’ sections: optional revit-parity — View Range: Bottom, Associated Level + 0’-0”	the range bottom relative to the level (a leading `-` reads below it) on a section or elevation, an optional level trim (`top level.L3 + 2'`) with no default
`depth` `depth -2'-0"`	length	either · required · default: the range bottom · plans only revit-parity — View Range: View Depth, Associated Level + 0’-0” — what it reaches draws beyond	how far below the bottom the plan still shows, as beyond
`name` `name "L1 Floor Plan"`	text	instance · optional	the printed title — the id references, the name prints

Reserved

Word	Rung	Meaning	Arrives with
`units`	type	how derived quantities display on this sheet — units are presentation, never a fact about the model	the metric / areas era — a tier on the view ?? viewtype ?? project cascade
`phase`	instance	the phase the query looks at the model as of	the phasing era — the phase filter, discipline’s twin (a filter on the query, never a kind)
`discipline`	instance	the discipline the view reads the model as (structural, mechanical…) — a filter on the query, and the graphic standard’s cell beside scale	the views/filters era — phase’s twin (a filter on the query, never a kind); object styles stay one standard, the view’s discipline picks the resolver cell the way its scale does

Datums

Datum	Shape	Status	Resolution	Rule
(the target)	plane	core	intrinsic	The level a plan is `of`, or the cut plane a section stands `at`, looking `to` its far clip. A dependency edge onto a datum — never onto an element (a wall edit must not move the drawing, decision 76(c)).
(the cut plane)	plane	core · plan	intrinsic	`cut` above the level a plan is `of`; a section’s plane IS its cut (D0265).
(the range top)	plane	core · plan	intrinsic	`top` above the level — what a plan classifies as above stops here (decision 74).
(the range bottom)	plane	core · plan	intrinsic	`bottom` relative to the level — the cut must sit between it and the top (D0522).
(the view depth)	plane	core · plan	intrinsic	`depth` relative to the level, at or below the bottom — what it reaches draws as beyond.
(the sheet scale)	—	core	—	The one non-geometric view fact: `scale`, required with a default like every other.
