一业内朋友让我写个快速创建标高的插件。
//创建标高
[TransactionAttribute(Autodesk.Revit.Attributes.TransactionMode.Manual)]
public class cmdDrawLevel : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string messages, ElementSet elements)
{
UIApplication app = commandData.Application;
Document doc = app.ActiveUIDocument.Document;
Selection sel = app.ActiveUIDocument.Selection;
try
{
Transaction ts = new Transaction(doc, "revit");
ts.Start();
//起始，间距，数量，前缀
double dStart = RevitTools.Unit.CovertToAPI(double.Parse(XmlTools.levelStart), DisplayUnitType.DUT_METERS);
double dDis = RevitTools.Unit.CovertToAPI(double.Parse(XmlTools.levelDis), DisplayUnitType.DUT_METERS);
int iNum = int.Parse(XmlTools.levelNum);
//创建起始标高
Level levelStart = doc.Create.NewLevel(dStart);
levelStart.Name = XmlTools.levelPre + ;
//
for (int i = ; i <= iNum; i++)
{
Level level = doc.Create.NewLevel(dStart + i * dDis);
level.Name = XmlTools.levelPre + (i + );
} ts.Commit();
}
catch (Exception ex)
{
TaskDialog.Show("error", "请检查是否命名重复。");
} return Result.Succeeded;
}
}

using System.Text; namespace RevitCodes
{
class XmlTools
{
public static string levelStart = "";
public static string levelDis = "";
public static string levelNum = "";
public static string levelPre = "F";
}
}
