SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It helps prevent and debug IFC model failures caused by using the wrong entity names, attributes, or types for a specific IFC schema version (IFC2X3 vs IFC4 vs IFC4X3), especially during migration.

Core Features & Use Cases

  • Schema mismatch diagnosis for common runtime errors like “entity not found” and attribute errors caused by version differences.
  • Version-aware entity selection to avoid IFC4/IFC4X3-only classes and removed entities when running code against older schemas.
  • Safe migration guidance using ifcpatch Migrate plus post-migration validation patterns to catch invalid outputs early.

Quick Start

Use the ifcos-errors-schema skill when Claude is generating IfcOpenShell code and you want it to diagnose schema compatibility issues between IFC2X3, IFC4, and IFC4X3.

Frequently Asked Questions about ifcos-errors-schema

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix IFC schema errors when migrating between IFC2X3 and IFC4?▼

IFC schema errors during migration stem from using IFC4 or IFC4X3-only entities in older schemas. Diagnose missing entities and mismatched attributes by checking model.schema, then apply schema-aware migration and validation to satisfy compatibility constraints.

How do I validate an IFC model after converting it to a different schema version?▼

Validate converted IFC models by running post-migration checks using ifcpatch Migrate patterns. This catches invalid outputs early by verifying correct entity naming rules and attribute alignment across IFC2X3, IFC4, and IFC4X3 schemas.

What is the best way to handle version-aware entity selection in IfcOpenShell?▼

Version-aware entity selection avoids using IFC4 or IFC4X3-only classes and removed entities when running code against older schemas. Check the schema version via model.schema to ensure correct entity naming rules before execution.

Does ifcpatch support schema migration from IFC2X3 to IFC4X3?▼

ifcpatch supports schema migration across IFC2X3, IFC4, and IFC4X3. Use ifcpatch Migrate to convert files, then run post-migration validation to detect invalid outputs and satisfy compatibility constraints.

How do I diagnose mismatched attributes in an IFC file?▼

Diagnose mismatched attributes by performing schema mismatch diagnosis to identify version differences. Compare entity attributes across IFC2X3, IFC4, and IFC4X3 schemas, using model.schema checks to pinpoint incompatible types and missing properties.
