Format compatibility: define where IFC building model will be used and what archival handoff must prove there.
Preserve the untouched IFC building model asset and record open format before changing geometry, materials, textures, hierarchy, or metadata for archival handoff.
For IFC building model archival handoff, Keep the sample file, application versions, import and export settings, screenshots, logs, and fallback format. Product, marketplace, regional, and compliance decisions still require the responsible specialist.
