Crate ifc_systems 

ifc-systems – Distribution systems: ports, connectivity and system grouping.

23 entities in IFC4. Turns a bag of pipes and ducts into a connected network that can be traced – the basis of any MEP analysis.

Module map

Module	Role
system	IfcSystem, IfcDistributionSystem and grouping
port	IfcDistributionPort and port assignment to elements
connectivity	IfcRelConnectsPorts and network traversal
flow	Flow direction and segment/fitting/terminal roles
error	Why a system query failed

Status

Implemented: systems with subtype-aware discovery and membership, ports and both element-attachment forms, the undirected connection graph with cycle-safe traversal, flow roles and direction, zones, and what a system serves: IfcRelServicesBuildings and the IFC4X3 ServicesFacilities references, read onto System and authored with serve_buildings.

Modules

authoring

Transactional authoring of systems, ports and their connections.

Structs

Connection

One stated port-to-port connection.

ConnectionGraph

An undirected port connection graph.

FlowNetwork

A network oriented by flow direction.

FlowQuery

The answer to a directed query.

NetworkGraph

A network view that also steps THROUGH elements, not just between them.

NotInSchema

An accessor that reads an attribute the declared release does not define for the entity’s type.

Port

A port as the file states it.

SpatialPlacement

Where one element sits in the spatial structure.

System

A system as the file states it, with its members resolved.

Zone

A zone: a grouping of spatial elements.

Enums

Attachment

How a port was attached to its element.

Direction

Which way a query walks.

ElementRole

What kind of flow element this is, by schema ancestry.

FlowDirection

Which way material or energy moves through a port.

RoleInconsistency

A disagreement between an element’s role and how its ports are directed.

SchemaGap

Why a per-attribute accessor bound to the model’s declared release could not produce a value.

SchemaResolutionError

Why a model’s declared schema release could not be resolved.

SchemaVersion

The IFC release a read binds to (re-exported from ifc-schema). Which IFC schema version a table describes.

SystemAnomaly

A system membership the file states but cannot support.

Functions

long_name_of

LongName of a single IfcZone, distinguishing “not authored” from “this release has no such attribute”.

ports

Every port in the file, with its owning element resolved.

role_inconsistencies

Check every element that owns ports for role/direction disagreement.

schema_of

Resolve the IFC release a model declares, from its FILE_SCHEMA header.

spatial_placements

Read spatial containment and referencing for every element that has either.

systems

Every system in the file, with members resolved and anomalies reported.

zones

Every IfcZone in the file, with WR1-valid members resolved.
