以下是在Revit 2016软件中,使用C#编写的选取CAD链接文件的图层中线的代码:
// 获取CAD链接文件的图层中线
public void GetCADLinkedFileLayerLines(Document doc, string cadFileName, string layerName)
{
// 获取CAD链接文件实例
FilteredElementCollector collector = new FilteredElementCollector(doc);
collector.OfCategory(BuiltInCategory.OST_RvtLinks);
Element linkedFile = collector.FirstElement();
RevitLinkInstance linkInstance = linkedFile as RevitLinkInstance;
// 获取CAD链接文件的图形文档
Document linkDoc = linkInstance.GetLinkDocument();
if (linkDoc == null)
return;
// 获取CAD链接文件的图层
LayerTable layerTable = linkDoc.Database.LayerTableId.GetObject(OpenMode.ForRead) as LayerTable;
if (layerTable == null)
return;
ObjectId layerId = ObjectId.Null;
foreach (ObjectId id in layerTable)
{
LayerTableRecord layer = id.GetObject(OpenMode.ForRead) as LayerTableRecord;
if (layer != null && layer.Name.Equals(layerName))
{
layerId = id;
break;
}
}
if (layerId == ObjectId.Null)
return;
// 获取CAD链接文件的图层中的所有线
BlockTable blockTable = linkDoc.Database.BlockTableId.GetObject(OpenMode.ForRead) as BlockTable;
if (blockTable == null)
return;
BlockTableRecord blockTableRecord = blockTable[BlockTableRecord.ModelSpace].GetObject(OpenMode.ForRead) as BlockTableRecord;
if (blockTableRecord == null)
return;
foreach (ObjectId id in blockTableRecord)
{
Entity entity = id.GetObject(OpenMode.ForRead) as Entity;
if (entity != null && entity.LayerId.Equals(layerId) && entity is Line)
{
Line line = entity as Line;
// 在Revit中创建与CAD链接文件图层中线相对应的Revit线
XYZ startPoint = new XYZ(line.StartPoint.X, line.StartPoint.Y, line.StartPoint.Z);
XYZ endPoint = new XYZ(line.EndPoint.X, line.EndPoint.Y, line.EndPoint.Z);
Line revitLine = Line.CreateBound(startPoint, endPoint);
// 将Revit线添加到文档中
using (Transaction trans = new Transaction(doc))
{
trans.Start("Create Line");
doc.Create.NewDetailCurve(doc.ActiveView, revitLine);
trans.Commit();
}
}
}
}
该代码首先获取CAD链接文件实例,然后获取CAD链接文件的图形文档和图层。接着,它遍历CAD链接文件的图层中的所有线,并在Revit中创建与CAD链接文件图层中线相对应的Revit线,并将其添加到文档中。
