Module arch 

ACAD Arch classes.

Walls, doors, stairs, spaces, slabs, curtain walls, structural members, and the style and display objects that belong to them are registered AEC classes. Opaque native bodies are preserved on same-version DWG saves. Supported typed edits update decoded native parameters and cached graphics together. Unsupported layouts return ArchEditError and leave the entity unchanged.

The calling guide is src/classes/arch/API.md.

Structs

AecPlacement

Placement stored by an Arch entity after its schema tag.

ArchEntityData

Class body of an Arch entity.

ArchObject

ContinuousWall

One connected run of wall segments, in baseline order.

DecodedAec

What can be read from any Arch class without a private schema.

MemberSize

Length and the two cross-section sizes of a beam or column.

OpeningSize

Width and height of a door, window, or opening, in drawing units.

StairSize

Run, width, and floor-to-floor height of a stair.

StoredNumber

One number found in the class bytes, with the role it plays for this entity.

StraightWallGeometry

One straight run of a wall: baseline start, baseline end, full thickness, and base height.

Enums

ArchEditError

Why an architecture edit left the entity unchanged.

ArchKind

Which Arch entity a class name represents.

NumberRole

What a stored number means.

PreviewRecord

One piece of the proxy-graphics preview.

Constants

ENTITY_CLASSES

DXF names of the Arch entities found in the Arch sample projects, with the C++ class ACAD registers for each.

Functions

centered_wall_profile

Closed preview of a center-justified straight wall.

continuous_wall_outline

Closed mitered outline of a center-justified wall chain.

continuous_walls

Walls in document grouped into continuous chains.

cpp_class_name

C++ class name registered for a known Arch entity, when this crate knows it. Callers that have the drawing’s CLASSES section should prefer that entry.

decode_profiles

Profiles carried by an entity’s proxy-graphics blob.

door

Create one standalone, unanchored native door at the origin.

door_size

Door leaf width and height, excluding the insertion elevation and swing clearance.

entities_anchored_to

Arch entities whose anchor depends on host.

is_architecture_name

Whether dxf_name is an ACAD Arch / MEP class.

kind_of

Entity kind for a known Arch DXF name.

map_profile_points

Map complete encoded profile runs, without scanning for isolated coordinate values.

member_size

Dimensions of the measured rectangular structural-member layout.

opening_size

Opening width along the wall, and its height.

polyline_from_type6

Decode a type-6 profile payload: u32 count, then count XYZ doubles.

reshape_rectangle

Reshape the first profile to a rectangle when it has the same point count.

set_ceiling_grid

Unsupported: native ceiling-grid placement has not been decoded.

set_column_grid

Unsupported: native column-grid placement has not been decoded.

set_continuous_wall

Replace every segment of chain so the baseline becomes points.

set_curtain_wall

Unsupported: native curtain-wall placement has not been decoded.

set_display_theme

Unsupported: native display-theme placement has not been decoded.

set_door

Set a door’s leaf width and height.

set_mass_element

Unsupported: native mass-element placement has not been decoded.

set_member

Set a rectangular member’s length along its decoded native placement axis. Cross-section changes are unsupported and leave the entity unchanged.

set_opening

Set an opening’s width along the wall and its height.

set_profile_bounds

Resize the bounds of an axis-aligned wall with a decoded native baseline. Native geometry for other entity kinds must be edited with a typed setter.

set_railing

Unsupported: native railing placement has not been decoded.

set_roof

Unsupported: native roof placement has not been decoded.

set_roof_slab

Unsupported: native roof-slab placement has not been decoded.

set_slab

Unsupported: native slab placement has not been decoded.

set_space

Unsupported: native space placement has not been decoded.

set_stair

Unsupported: linked stair rise, tread, and offset parameters are not decoded. The entity and its graphics stay unchanged.

set_wall

Rewrite one straight wall onto a new baseline.

set_window

Set a window’s plan width and height.

set_window_assembly

Unsupported: native window-assembly placement has not been decoded.

stair_size

Dimensions of the measured straight-stair layout.

wall

Create one straight, centered wall in the world XY plane.

window

Create one standalone, unanchored native window at the origin.

window_size

Window width and height. The insertion-point Z coordinate is the sill elevation.
