使用C#在Revit中旋转多个图元

在Revit中使用C#旋转多个图元的方法如下:

  1. 首先,你需要使用Revit API来编写C#代码。Revit API是一组用于与Revit软件进行交互的类和方法。
  2. 在C#代码中,你需要使用Revit的Transaction机制来确保对Revit模型的修改是可撤销的。你可以使用以下代码创建一个新的事务:
代码语言:txt
复制
Transaction transaction = new Transaction(doc, "Rotate Elements");
transaction.Start();

其中,doc是当前的Revit文档对象,"Rotate Elements"是事务的名称。

  1. 接下来,你需要获取要旋转的图元。你可以使用Revit的过滤器来选择特定类型的图元。例如,如果你想旋转所有的墙体,你可以使用以下代码:
代码语言:txt
复制
FilteredElementCollector collector = new FilteredElementCollector(doc);
ICollection<Element> elements = collector.OfClass(typeof(Wall)).ToElements();

这将返回一个包含所有墙体元素的集合。

  1. 然后,你可以使用Revit的旋转方法来旋转图元。例如,如果你想将图元顺时针旋转90度,你可以使用以下代码:
代码语言:txt
复制
foreach (Element element in elements)
{
    Location location = element.Location;
    if (location is LocationPoint)
    {
        LocationPoint locationPoint = location as LocationPoint;
        XYZ point = locationPoint.Point;
        ElementTransformUtils.RotateElement(doc, element.Id, point, Math.PI / 2);
    }
}

这将遍历所有的图元,并将其旋转90度。

  1. 最后,你需要提交事务以保存对Revit模型的修改,并结束事务。你可以使用以下代码完成这一步骤:
代码语言:txt
复制
transaction.Commit();
transaction.Dispose();

完整的代码示例如下:

代码语言:txt
复制
Transaction transaction = new Transaction(doc, "Rotate Elements");
transaction.Start();

FilteredElementCollector collector = new FilteredElementCollector(doc);
ICollection<Element> elements = collector.OfClass(typeof(Wall)).ToElements();

foreach (Element element in elements)
{
    Location location = element.Location;
    if (location is LocationPoint)
    {
        LocationPoint locationPoint = location as LocationPoint;
        XYZ point = locationPoint.Point;
        ElementTransformUtils.RotateElement(doc, element.Id, point, Math.PI / 2);
    }
}

transaction.Commit();
transaction.Dispose();

这样,你就可以使用C#在Revit中旋转多个图元了。

一行代码, Java 怎样把List 转成 Map 的方法( Java 8 中的Stream API )

java.util.stream public interface Collector<T, A, R> A mutable reduction operation that accumulates input elements into a mutable result container, optionally transforming the accumulated result into a final representation after all input elements have been processed. Reduction operations can be performed either sequentially or in parallel. Examples of mutable reduction operations include: accumulating elements into a Collection; concatenating strings using a StringBuilder; computing summary information about elements such as sum, min, max, or average; computing "pivot table" summaries such as "maximum valued transaction by seller", etc. The class Collectors provides implementations of many common mutable reductions. A Collector is specified by four functions that work together to accumulate entries into a mutable result container, and optionally perform a final transform on the result. They are: creation of a new result container (supplier()) incorporating a new data element into a result container (accumulator()) combining two result containers into one (combiner()) performing an optional final transform on the container (finisher()) Collectors also have a set of characteristics, such as Collector.Characteristics.CONCURRENT, that provide hints that can be used by a reduction implementation to provide better performance. A sequential implementation of a reduction using a collector would create a single result container using the supplier function, and invoke the accumulator function once for each input element. A parallel implementation would partition the input, create a result container for each partition, accumulate the contents of each partition into a subresult for that partition, and then use the combiner function to merge the subresults into a combined result. To ensure that sequential and parallel executions produce equivalent results, the collector functions must satisfy an identity and an associativity constraints. The identity constraint says that for any partially accumulated result, combi
