由于Revit的版本问题,在网上找的生成墙图元的代码,在我机器上的Revit 2016中编译不能通过,通过多次调试,终于找到在revit 2016中使用API生成墙图元的代码,现在贴出来。
下面的代码在Revit 2016 + VS2013的环境下通过。
class CreateWall : IExternalCommand
{
public static Document RevitDoc;
public static Autodesk.Revit.ApplicationServices.Application RevitApp;
public Autodesk.Revit.UI.Result Execute(ExternalCommandData commandData,
ref string message, Autodesk.Revit.DB.ElementSet elements)
{
RevitApp = commandData.Application.Application;
var uiDoc = commandData.Application.ActiveUIDocument;
if (uiDoc == null)
{
message = "Please open a document";
return Result.Failed;
} RevitDoc = commandData.Application.ActiveUIDocument.Document;
var uiSel = commandData.Application.ActiveUIDocument.Selection; Transaction transaction = new Transaction(RevitDoc, "TestScript.CreateNewInstanceWithNewType");
transaction.Start();
try
{
var typeFilter = new ElementClassFilter(typeof(WallType));
FilteredElementCollector wallTypes = new FilteredElementCollector(RevitDoc);
wallTypes = wallTypes.WherePasses(typeFilter);
WallType walltype = null;
foreach (WallType wallType in wallTypes)
{
walltype = wallType;
break;
}
if (walltype != null)
{
//创建新的墙类型,使用Duplicate方法
var newtype = walltype.Duplicate(walltype.Name + "_new"); //可以在这里修改墙类型的参数,例如修改吸收率
var para = walltype.get_Parameter(BuiltInParameter.ANALYTICAL_ABSORPTANCE);
if (para != null && para.StorageType == StorageType.Double && para.IsReadOnly == false)
{
para.Set(2.0);
} //找到一个标高
Level level = null;
var levelFilter = new ElementClassFilter(typeof(Level));
FilteredElementCollector levels = new FilteredElementCollector(RevitDoc);
levels = levels.WherePasses(levelFilter);
foreach (Level element in levels)
{
level = element;
break;
} //创建墙
var wall = Wall.Create(RevitDoc, Line.CreateBound(new XYZ(0, 0, 0), new XYZ(10, 0, 0)),
newtype.Id, level.Id, 20, 0, false, false);
TaskDialog.Show("wall creation", "wall created, id = " + wall.Id);
}
transaction.Commit();
}
catch (Exception ex)
{
message = ex.ToString();
transaction.RollBack();
return Result.Failed;
} return Result.Succeeded;
}
}
