所以,如果你需要用数学式子计算一个值,那就只有用表达式返回这个值,没有其他语法结构可用,因为否则就无法处理这个值。
And so while you needed expressions for math to work, there was no point in making anything else return a value, because there could not be anything waiting for it.
如果某个行是分层结构中的叶子节点,则返回的值为 1,否则返回值为 0 。
The value of 1 is returned if the row is a leaf in the hierarchy, otherwise a value of 0 is returned.
如果你的模型是一个连接在两边的细线的结构,你可以去稍微薄到0.8毫米,否则我们建议至少1毫米的厚度。
If your feature is a thin wire connected on both sides, you can go slightly thinner to 0.8 mm, otherwise we recommend at least 1 mm thickness.
