How this service works
Resolve nested BIM product placements into complete world transforms.
Output
Returns the fully composed world-space transform for each placement in the input chain, resolving all parent references so that each element's absolute position and orientation in world coordinates is available as a combined transformation matrix or equivalent representation.
Example use cases
BIM element absolute position lookup
“I have an IFC model with 4 nested local placements, each referencing the previous as parent. The root has location [0,0,0], axis [0,0,1], reference [1,0,0] and no parent; child 1 has location [5,0,0], axis [0,0,1], reference [1,0,0] and parent 0; child 2 has location [0,3,0], axis [0,0,1], reference [1,0,0] and parent 1. Can you resolve the full chain to get the final world-space transform for child 2?”
Architectural clash detection preprocessing
“Before running clash detection, I need to convert all these nested IFC axis2 placements into absolute world coordinates. Here are 10 placements forming a hierarchy with indices 0 through 9 — please resolve each one's parent chain and give me the composed world transforms.”
Structural element geolocation for GIS export
“I'm exporting IFC structural elements to a GIS system and need their absolute world positions. I have a 3-level deep placement chain: a site placement at [100,200,0] with no parent, a building placement at [10,0,0] with parent 0, and a floor slab at [0,0,3] with parent 1. Can you resolve the complete chain to give me the slab's world-space transform?”

Endpoint
POSThttps://detect.halowerk.com/v1/F-TD2000-GEO-INDUSTRY-B002/ifc-axis2-local-placement-parent-chain-transform?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve IFC IfcAxis2Placement3D or IfcLocalPlacement hierarchies into absolute world-space transforms in a BIM/IFC workflow. It is purpose-built for the IFC placement chain composition problem and handles up to 32 placements in a single call, making it ideal for pre-processing BIM data for clash detection, GIS export, or visualization pipelines.
Side effects
- Circular parent references in the placement chain cause infinite loop or error
- Parent index out of range (exceeds 31 or references non-existent placement) returns validation error
- Malformed axis or reference vectors (not unit vectors or not 3-element arrays) may cause computation errors
- Too many placements (over 32) rejected by schema validation
- Invalid claim object causes authentication/authorization failure
- Coordinate values outside [-1000000, 1000000] range rejected
