move_elements
Batch move Revit elements with precise coordinate adjustments. Automates unit conversion (mm to feet), provides detailed results, and handles errors effectively via JSON-RPC 2.0.
Instructions
移动Revit元素，支持批量操作，遵循JSON-RPC 2.0规范。 mcp_tool使用时params不要有任何注释信息
特性:
支持批量移动多个Revit元素
自动处理单位转换（毫米转英尺）
返回移动后的元素详细信息（使用ElementModelRequest格式）
完善的错误处理机制
参数: ctx (Context): FastMCP上下文对象 method (str): JSON-RPC方法名，默认为"MoveElements" params (List[Dict]): 移动参数列表，每个字典包含: - elementId (str): 要移动的元素ID - x (float): X方向移动距离（毫米） - y (float): Y方向移动距离（毫米） - z (float): Z方向移动距离（毫米）
返回: dict: JSON-RPC 2.0格式的响应，结构为: 成功时: { "jsonrpc": "2.0", "result": [ { "elementId": "移动后的元素ID", "name": "元素名称", "familyName": "族名称" }, ... ], "id": request_id } 失败时: { "jsonrpc": "2.0", "error": { "code": int, "message": str, "data": any }, "id": request_id }
示例: response = move_elements(ctx, params=[ {"elementId": "123456", "x": 100, "y": 200, "z": 0}, {"elementId": "789012", "x": -50, "y": 0, "z": 300} ])

Implementation Reference
- xml_revit_mcp/server.py:50-55 (registration)The 'move_elements' tool is included in the GENERAL_TOOLS list used for registration.GENERAL_TOOLS = [ get_commands, execute_commands, call_func, find_elements, update_elements, delete_elements, parameter_elements, get_locations, move_elements, show_elements, active_view, get_selected_elements, link_dwg_and_activate_view, get_view_data ]
- xml_revit_mcp/server.py:144-146 (registration)Loop that registers all tools in GENERAL_TOOLS, including 'move_elements', using the FastMCP tool decorator.# 注册通用工具 for tool in GENERAL_TOOLS: server.tool()(tool)
- xml_revit_mcp/server.py:248-248 (registration)Call to register_tools which registers the 'move_elements' tool.register_tools(mcp)
