Implements SPECIFICATION.md §6 BCF→ifc:// direction: parse a BCF 3.0 REST viewpoint dict (camera, clips, selection/visibility) and apply it to a base IfcUrl to produce an ifc:// URL string. IfcUrl.to_string() serialises any IfcUrl back to a valid ifc:// URL, enabling round-trip parse→to_string for all URL forms. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
