class_name ObjectPlaceTool
extends EditorTool
## Places a new catalog object into the chunk at a given transform.
##
## `args`: `catalog_id` (String, required), `position` (Vector3), `rotation`
## (Vector4 quaternion, optional, default identity), `scale` (Vector3,
## optional, default ONE), `properties` (Dictionary, optional, merged in).
##
## Returns the new object's id (String) on success, or "" on failure
## (unknown catalog_id).
