IFC Schema Validation Errors

Diagnose and fix the errors raised by IFC schema validation : EXPRESS WHERE and global RULE violations, instantiation of abstract entities, cardinality and attribute-type errors, and the normative Gherkin-rule layer. Also : how to read a buildingSMART validation report without misinterpreting it.

For the validation MODEL (the conceptual three-tier hierarchy) see ifc-core-validation. For STEP syntax and character-encoding errors see ifc-errors-encoding-issues. For deprecated-entity errors see ifc-errors-version-mismatch.
