Ifcledger is a focused data microscope for IFC STEP files. It inventories complete records, resolves selected openBIM relationships, and keeps every finding tied to exact source instance identifiers.
Trace
Search by class, name, path, GlobalId, or STEP ID. Open any indexed record to inspect forward and reverse references.
Audit
Review evidence for duplicate identifiers, dangling references, unnamed containers, aggregation cycles, missing units, and large coordinates.
Compare
Match rooted objects by compressed GlobalId and surface additions, removals, renames, class changes, and linked-data changes.

Clear about what it does not do
Ifcledger does not render geometry, author IFC, certify schema conformance, validate an IDS, detect geometric clashes, estimate cost, approve a delivery, or provide contractual acceptance.
Use its source-linked findings as review evidence inside the project's approved authoring, coordination, validation, and quality workflow.
