参数添加 dynamo

news 来源：原创 2024/5/6 0:12:19

以下是Python节点的输入顺序：

IN [0] - 参数名称作为字符串。这将是你的参数的名称。

IN [1] - Group Name as String。这将是共享参数组名称。该参数将被存储在该组中。

IN [2] - 参数类型，它定义是否是一个是/否，文本，整数等参数类型。在左边有一个单独的Python节点，枚举项目中可用的所有参数类型，以便获取其中的一个。

IN [3] - 可见？这是一个布尔真/假，这将使参数用户可见（它将显示在元素的属性中）或不可见（用户不能看到参数，它只能通过API访问）

IN [4] - 元素类别。这是一个你想添加参数到ex的类别。通用模型或家具。

IN [5] - 参数组。这是在UI中显示时参数存储的组。当您选择一个元素时，每个参数都在一个组内。最常用的是图形，文本，标识等，但还有更多可用于放置您的参数。

IN [6] - 实例？这是一个布尔真/假，确定这将是一个实例或类型参数。

一旦你运行这个定义，它将在共享参数文件中创建参数，并将其添加到项目中。
