我正在使用Jeremy Tammik的模板编写Revit的Addin,这为我创建了一个带按钮的功能区。
我正在读取一个Excel文件,选择行和起点。
My Ribbon
My WinForm
用户完成输入后,他应该单击“完成”按钮(在我的情况下是缺少的^^),它应该在项目中生成一些FamilyInstances,而不关闭WinForm。
ShowDialog()
对吗?因为这将为我创建一个模态表单,然后由于Revit窗口显示为灰色,所以我无法获得任何用户输入
Show()
对吗?由于我的代码将继续
有人可以帮助我找到解决我问题的正确方法。我不太确定我的方法是否最终会奏效
我试图在WinForm类中进行事务处理,但是我知道这行不通。
我正在考虑一个单独的类,该类将保存用户输入,第二个ExternalCommand类将执行该事务以创建FamilyInstances。
我查看了SDK,发现了ModelessForm_ExternalEvent,但我很难理解它...
我也找到了这些帖子,并试图理解它们:

Revit Pick element from WinForm
我有一个创建功能区和按钮的应用程序类:
class App : IExternalApplication
{
public Result OnStartup(UIControlledApplication a)
{
// Ingenieurbau Reiter erstellen
string engineerTabName = "Ingenieurbau Addin";
a.CreateRibbonTab(engineerTabName);
// Gruppen erstellen
RibbonPanel lswPanel = a.CreateRibbonPanel(engineerTabName, "Lärmschutzwand");
// Buttons hinzufügen
AddLswPushButtons(lswPanel);
AddTestPushButton(lswPanel);
return Result.Succeeded;
}
private void AddLswPushButtons(RibbonPanel panel)
{
// Strings erzeugen
string lswName1 = "LSW Daten einlesen";
string lswAssemblyName1 = Assembly.GetExecutingAssembly().Location;
string lswClassName1 = "IngenieurbauAddin1.Lsw.DataInput";
// ButtonData erzeugen
PushButtonData lswPushButtonData1 = new PushButtonData(lswName1, lswName1, lswAssemblyName1, lswClassName1);
// ButtonData dem Panel hinzufügen und in einen PushButton umwandeln
PushButton lswPushButton1 = panel.AddItem(lswPushButtonData1) as PushButton;
// ButtonBild einfügen
lswPushButton1.LargeImage = PngImageSource("IngenieurbauAddin1.Resources.Excel.png");
}
}
我有一个显示形式的DataInput类:
[Transaction(TransactionMode.Manual)]
class DataInput : IExternalCommand
{
public Result Execute(
ExternalCommandData commandData,
ref string message,
ElementSet elements)
{
UIApplication uiapp = commandData.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Application app = uiapp.Application;
Document doc = uidoc.Document;
// Form instanziieren
DataInputForm dataInputForm = new DataInputForm(uidoc);
// Form starten
dataInputForm.Show();
return Result.Succeeded;
}
}
这是我的DataInputForm类(我知道PlaceFamily
不起作用):
public partial class DataInputForm : System.Windows.Forms.Form
{
private UIDocument UIDocument { get; set; }
private Document Document { get; set; }
public DataInputForm(UIDocument uiDocument)
{
UIDocument = uiDocument;
Document = uiDocument.Document;
InitializeComponent();
}
private void btnSelectPoint_Click(object sender, EventArgs e)
{
Hide();
SelectionHelper selectionHelper = new SelectionHelper(Document);
XYZ point = selectionHelper.SelectLineEndPoint(UIDocument);
labelPointLocalXValue.Text = Math.Round(point.X, 3).ToString();
labelPointLocalYValue.Text = Math.Round(point.Y, 3).ToString();
labelPointLocalZValue.Text = Math.Round(point.Z, 3).ToString();
Show();
PlaceFamily(point);
}
private void PlaceFamily(XYZ point)
{
FamilySymbolHelper familySymbolHelper = new FamilySymbolHelper(Document);
FamilyInstanceHelper familyInstanceHelper = new FamilyInstanceHelper(Document);
FamilySymbol famSym = familySymbolHelper.FamilySymbolByName("Master-Bauteil");
try
{
using (Transaction t = new Transaction(Document, "Familie platzieren"))
{
t.Start();
FamilyInstance famInst = familyInstanceHelper.FamilyInstanceByPoint(famSym, point);
t.Commit();
}
}
catch (Exception e)
{
TaskDialog.Show("Error", e.Message);
}
}
}
我只想输入输入(Excelfile,线,点),然后它应该为我生成FamilyInstances。但是我现在有点卡住了^^。
感谢您的帮助。

您在ExternalCommand中使用了Form.Show()方法,因此它是无模式窗口。 在此窗口中,有一个按钮,用户单击它,然后选择一个终点。 好吧,问题是:您无法在Revit API上下文之外启动事务! 我建议您研究Revit API示例,其中有一个名为“无模式对话框”的目录。它清楚地演示了如何通过外部事件使用无模式对话框。 https://thebuildingcoder.typepad.com/blog/2015/12/external-event-and-10-year-forum-anniversary.html

调用dataInputForm.Show();
这是修改后的代码:
[Transaction(TransactionMode.Manual)]
internal class DataInput : IExternalCommand
{
private static WindowHandle _hWndRevit = null;
private void SetHandle()
{
if (null == _hWndRevit)
{
Process process
= Process.GetCurrentProcess();
IntPtr h = process.MainWindowHandle;
_hWndRevit = new WindowHandle(h);
}
}
public Result Execute(
ExternalCommandData commandData,
ref string message,
ElementSet elements)
{
SetHandle();
UIApplication uiapp = commandData.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Application app = uiapp.Application;
Document doc = uidoc.Document;
// Form instanziieren
var dataInputForm = new DataInputForm(uidoc);
// Form starten
if (_hWndRevit != null)
{
dataInputForm.Show(_hWndRevit);
}
else
{
return Result.Failed;
}
return Result.Succeeded;
}
}
