object.Value

对象

类型：动态块引用属性，IDPair

此属性适用的对象。

属性值

只读：否 （DynamicBlockReferenceProperty）， Yes （IDPair）

类型：Variant （DynamicBlockReferenceProperty）， Long_PTR （IDPair）

DynamicBlockReferenceProperty：属性的当前值。

IDPair：操作中新创建的克隆对象的对象ID。CopyObjects

言论

动态块引用属性：如果无法设置指定的属性值，则不会返回任何错误。例如，如果属性具有允许值列表或最小-最大范围，并且提供的值不在列表中或超出范围，则不会返回任何错误。

IDPair：使用属性获取源对象的对象 ID。Key
