Edit attributes

Create, modify and delete attributes (layers, layer combinations, lines, fills, zone categories, pen tables, profiles, building materials, composites, surfaces) and set attribute property values (Tapir). DRY-RUN BY DEFAULT; pass dry_run=false to commit. Each change has one action key whose value is the type: {"create": "Layer", "name": "X", } makes a new one and NEVER overwrites (an existing name is skipped, with what would change and the modify to send instead); {"modify": "Composite", "attribute": "", } changes an existing one (name renames; fields not given keep their value, including what Tapir's own overwrite would drop: a composite's useWith, a building material's texts); {"modify": ..., "properties": {"Group/Name": "value"}} sets property values; {"delete": "Fill", "attribute": ...} deletes. Fields use Tapir's names and units (metres, radians, pen numbers); a field holding another attribute (buildingMaterialId, lineTypeId, fillId, cutFillIndex, a layer combination's layers[].attributeId) takes its name. changes=[] lists every type's fields; list_attributes(details=true) shows current values in the same form. The dry run shows current -> new and skips with the reason anything Archicad or Tapir would refuse or silently get wrong: misspelt enums, unknown references, Archicad's own index 1 attributes, a layer delete while elements are on the layer (it would delete them) or without the floor plan active. In Teamwork the attribute type's set must be reserved (reserve_elements object_sets). Attribute writes cannot be undone. A commit returns applied (read back), not_applied, failed (grouped) and stopped.
