OpenBIM and IFC Collaboration
Technical best practices for OpenBIM and IFC Collaboration inside Archicad.
Definition
OpenBIM and IFC Collaboration supports coordination using buildingSMART specifications, mapping elements accurately.
Why it matters
Fosters multi-discipline collaboration without requiring standard software monocultures.
Technical Deep Dive & Core Mechanics
At the database tier, OpenBIM and IFC Collaboration within the Archicad ecosystem relies on a structured, relational object graph rather than simple visual vectors. Each instance is tracked by a unique Global Unique Identifier (GUID), linking its geometry to semantic parameters in the project database. When rendering or scheduling, the engine performs real-time queries to resolve parameter values and apply visibility graphic overrides.
Advanced Troubleshooting & Error Diagnostics
- Topological Reference Orphaned (Revit Warn 102-A): Occurs when a sketch or parameter reference is lost due to a parent wall/slab deletion. Resolution: Edit the sketch plane and re-associate the broken constraints to active levels.
Cross-Discipline Collaboration & Handoff
In global multi-office projects, OpenBIM and IFC Collaboration is a high-frequency handoff node between diverse software packages. During cross-platform export (for example, exporting Archicad drawings to IFC for coordination in Navisworks or Solibri, or converting mechanical STEP files into BIM detail families):
Common pitfalls
- Using incorrect IFC translator settings causing parameter loss
- Forgetting to align project origins during cross-platform model setup

Relevant Archicad FAQs
❓ How do I configure hotlinked modules in Archicad?
Go to File > External Content > Place Hotlinked Module, select the source file (PLN or MOD), and configure translation and layer options.
❓ What is the best way to export IFC files for Revit coordination?
Use the built-in 'Export to Revit' IFC translator, which optimizes Archicad classification mappings to Revit category classes.
❓ How do I automate layout numbering in Publisher Sets in Archicad?
Use Archicad's Auto-Text templates in your Master Layouts. The layout book will automatically sequence sheet numbers during publish.
