Revit 2013 API提供了一个新功能用FilledRegion.Create() 方法来创建填充区域。
函数的签名如下：

1. <p><font color="#333333" face="Arial"><span style="line-height: 26px;">
   
2. </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">[csharp] view plaincopy</span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">public static FilledRegion Create(  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    Document document,  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    ElementId typeId,  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    ElementId viewId,  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    IList<CurveLoop> boundaries  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">)  </span></font></p>

复制代码

调用这个函数之前，需要预备好填充区域的填充类型(FilledRegionType) id, 放在在哪个文档的那个视图中，以及填充区域的边界封闭曲线。

下面的代码展示了如何创建

1. <p><font color="#333333" face="Arial"><span style="line-height: 26px;">
   
2. </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">[csharp] view plaincopy</span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">FilteredElementCollector collector = new FilteredElementCollector(_doc);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">IList<Element> fillRegionTypes = collector.OfClass(typeof(FilledRegionType)).ToElements();  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">IEnumerable<FilledRegionType> myPatterns =  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    from pattern in fillRegionTypes.Cast<FilledRegionType>()  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    where pattern.Name.Equals("Diagonal Crosshatch")  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    select pattern;  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">foreach (FilledRegionType frt in fillRegionTypes)  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">{  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  List<CurveLoop> profileloops = new List<CurveLoop>();  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  XYZ[] points = new XYZ[5];  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  points[0] = new XYZ(0.0, 0.0, 0.0);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  points[1] = new XYZ(10.0, 0.0, 0.0);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  points[2] = new XYZ(10.0, 10.0, 0.0);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  points[3] = new XYZ(0.0, 10.0, 0.0);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  points[4] = new XYZ(0.0, 0.0, 0.0);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  CurveLoop profileloop = new CurveLoop();  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  for (int i = 0; i < 4; i++)  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  {  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    Line line = _app.Create.NewLineBound(points[i], points[i + 1]);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">    profileloop.Append(line);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  }  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  profileloops.Add(profileloop);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  ElementId activeViewId = _doc.ActiveView.Id;  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  FilledRegion filledRegion = FilledRegion.Create(_doc, frt.Id, activeViewId, profileloops);  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">  break;  </span></font></p><p><font color="#333333" face="Arial"><span style="line-height: 26px;">}   </span></font></p>
