create_levels
Create multiple building levels in Revit with batch processing, automatic unit conversion from millimeters to feet, and conflict resolution for level names.
Instructions
在Revit中创建标高，支持批量创建，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:
支持批量创建多个标高
自动处理单位转换（毫米转英尺）
自动处理标高名称冲突
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"CreateLevels" params (List[Dict]): 标高参数列表，每个字典包含: - elevation (float): 标高高度（毫米） - name (str, optional): 标高名称（可选，默认为"Level_{elevation}"）
返回: dict: JSON-RPC 2.0格式的响应，结构为: 成功时: { "jsonrpc": "2.0", "result": [ { "elementId": "创建的标高元素ID", "name": "标高名称", "familyName": "标高族名称" }, ... ], "id": request_id } 失败时: { "jsonrpc": "2.0", "error": { "code": int, "message": str, "data": any }, "id": request_id }
示例: # 创建多个标高 response = create_levels(ctx, params=[ {"elevation": 8000, "name": "Level_3"}, {"elevation": 12000} # 自动生成名称"Level_12000" ])

Implementation Reference
- xml_revit_mcp/server.py:41-44 (registration)The create_levels tool is included in the ARCHITECTURAL_TOOLS list, which groups tools for registration with the MCP server.ARCHITECTURAL_TOOLS = [ create_levels, create_floor_plan_views, create_grids, create_walls, create_floors, create_door_windows, create_rooms, create_room_tags, create_family_instances, create_sheets ]
- xml_revit_mcp/server.py:134-147 (registration)The register_tools function iterates over ARCHITECTURAL_TOOLS (including create_levels) and registers each tool function using the FastMCP server's tool decorator.def register_tools(server: FastMCP) -> None: """注册所有工具到MCP服务器""" # 注册建筑工具 for tool in ARCHITECTURAL_TOOLS: server.tool()(tool) # 注册MEP工具 for tool in MEP_TOOLS: server.tool()(tool) # 注册通用工具 for tool in GENERAL_TOOLS: server.tool()(tool)
- xml_revit_mcp/server.py:248-248 (registration)Explicit call to register_tools(mcp), which registers the create_levels tool among others on the MCP server instance.register_tools(mcp)
- xml_revit_mcp/server.py:58-94 (helper)Utility function to get or create a persistent RevitConnection, which tool handlers like create_levels would use to send commands to the Revit plugin.def get_revit_connection() -> RevitConnection: """ 获取或创建持久的Revit连接 返回: RevitConnection: 与Revit的连接对象 异常: Exception: 连接失败时抛出 """ global _connection, _enabled if _connection is not None: try: # 测试连接是否有效 result = _connection.send_command("get_polyhaven_status") _enabled = result.get("enabled", False) return _connection except Exception as e: logger.warning(f"现有连接已失效: {str(e)}") try: _connection.disconnect() except: pass _connection = None # 创建新连接 if _connection is None: _connection = RevitConnection(host="localhost", port=_port) if not _connection.connect(): logger.error("无法连接到Revit") _connection = None raise Exception( "无法连接到Revit。请确保Revit插件正在运行。") logger.info("已创建新的持久连接到Revit") return _connection
- Core method in RevitConnection that sends JSON-RPC commands (e.g., 'CreateLevels') to the Revit plugin; tool handlers would call this with command_type='create_levels' or similar.def send_command(self, command_type: str, params: Union[Dict[str, Any], List[Dict[str, Any]]] = None) -> Dict[ str, Any]: """ 向Revit发送命令并返回响应 参数: command_type (str): 命令类型 params (Dict[str, Any] 或 List[Dict[str, Any]]): 命令参数 返回: Dict[str, Any]: 命令响应 异常: ConnectionError: 连接错误 TimeoutError: 请求超时 ValueError: 参数或响应无效 Exception: 其他错误 """ # 确保连接 if not self.sock and not self.connect(): raise ConnectionError("无法连接到Revit") try: logger.info(f"发送命令: {command_type}") logger.debug(f"命令参数: {params}") # 导入并创建请求对象 from .rpc import JsonRPCRequest, JsonRPCResponse command = JsonRPCRequest(method=command_type, params=params) command_json = json.dumps(command.__dict__) # 发送命令 self.sock.sendall(command_json.encode('utf-8')) logger.debug("命令已发送，等待响应...") # 使用 receive_full_response 接收完整数据流 response_data = self.receive_full_response() logger.debug(f"已接收 {len(response_data)} 字节数据") # 解析响应 try: response_dict = json.loads(response_data.decode('utf-8')) response = JsonRPCResponse( id=response_dict.get("id"), result=response_dict.get("result"), error=response_dict.get("error") ) except json.JSONDecodeError as e: logger.error(f"无法解析Revit响应: {str(e)}") if response_data: logger.error(f"原始响应 (前200字节): {response_data[:200]}") raise ValueError(f"无效的Revit响应: {str(e)}") # 处理错误 if response.error: error_message = response.error.get("message", "未知错误") error_code = response.error.get("code", -1) error_data = response.error.get("data") logger.error(f"Revit错误 (代码: {error_code}): {error_message}") if error_data: logger.error(f"错误数据: {error_data}") raise Exception(f"Revit错误: {error_message}") return response.result or {}
