Revit二次开发——剪切

1、实体构建的剪切与连接：

	namespace CreateInstanceTest
 {
[Transaction(TransactionMode.Manual)]
class TestCut : IExternalCommand
{
    Result IExternalCommand.Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
    {
        UIApplication uiApp = commandData.Application;
        UIDocument uiDoc = uiApp.ActiveUIDocument;
        Document doc = uiApp.ActiveUIDocument.Document;

        Element elem_1 = doc.GetElement(uiDoc.Selection.PickObject(ObjectType.Element));
        Element elem_2 = doc.GetElement(uiDoc.Selection.PickObject(ObjectType.Element));

        using (Transaction trans = new Transaction(doc))
        {
            trans.Start("Cut Element");
            SolidSolidCutUtils.AddCutBetweenSolids(doc, elem_1, elem_2);//两个标准族实例的剪切
            ICollection list = SolidSolidCutUtils.GetCuttingSolids(elem_1);//获取剪切实例的个数
            //判断两个构件是否连接

            if (JoinGeometryUtils.AreElementsJoined(doc, elem_1, elem_2) == true)
            {
                JoinGeometryUtils.UnjoinGeometry(doc, elem_1, elem_2); //取消连接
                SolidSolidCutUtils.RemoveCutBetweenSolids(doc, elem_1, elem_2);//取消剪切
                JoinGeometryUtils.JoinGeometry(doc, elem_1, elem_2);//连接
                JoinGeometryUtils.SwitchJoinOrder(doc, elem_1, elem_2);//切换连接顺序
                ICollection listid = JoinGeometryUtils.GetJoinedElements(doc, elem_1);//获取连接对象的个数
            }
            trans.Commit();
        }
        return Result.Succeeded;
    }
}

}

2、空心剪切

public class TestVoidCut : IExternalCommand
{
    public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
    {
        UIApplication uiApp = commandData.Application;
        UIDocument uiDoc = uiApp.ActiveUIDocument;
        Document doc = uiApp.ActiveUIDocument.Document;

        Wall wall = doc.GetElement(uiDoc.Selection.PickObject(ObjectType.Element))as Wall;
        Element elem = doc.GetElement(uiDoc.Selection.PickObject(ObjectType.Element));

        using (Transaction trans = new Transaction(doc))
        {
            trans.Start("Void Cut");

            InstanceVoidCutUtils.AddInstanceVoidCut(doc, wall, elem);
            trans.Commit();
        }
        return Result.Succeeded;
    }
}
