我正在尝试使用 Revit API 和 Idling 事件处理程序来自动化 Revit 2017 中的 PDF 打印过程。我使用 OpenDocumentFile 方法打开 Revit 文档,而不是在任何地方使用 ActiveUIDocument。此过程正在生成 InvalidOperationException。我不确定为什么会给出例外,或者是否允许使用 Revit API。
期刊输出:
' 1:< 0 <-pushSettingsIntoDriver
' C 27-Sep-2016 14:45:22.641; 1:< ExportToRequestedFormat() : Pdf Print Exception : InvalidOperationExceptionAt least one view from the view set could not be printed.

背后代码:
using (FilteredElementCollector viewCollector = new FilteredElementCollector(doc))
{
ViewSet set = new ViewSet();
ElementClassFilter viewFilter = null;
PrintManager pm = PrinterDriverSettings.GetPrintManager(doc, _ifcSaveFile, PrinterDriver.Bullzip);
switch (_pdfExportSetting)
{
case PDFExportOptions.SheetsOnly:
viewFilter = new ElementClassFilter(typeof(Autodesk.Revit.DB.ViewSheet));
viewCollector.WherePasses(viewFilter);
foreach (Autodesk.Revit.DB.ViewSheet vw in viewCollector)
{
if (vw.CanBePrinted && !vw.IsTemplate)
set.Insert(vw);
}
break;
case PDFExportOptions.ViewsOnly:
viewFilter = new ElementClassFilter(typeof(Autodesk.Revit.DB.View));
viewCollector.WherePasses(viewFilter);
foreach (Autodesk.Revit.DB.View vw in viewCollector)
{
if (vw.CanBePrinted && !vw.IsTemplate && !(vw.GetType() == typeof(ViewSheet))) //Skip sheets
set.Insert(vw);
}
break;
case PDFExportOptions.ViewsAndSheets:
viewFilter = new ElementClassFilter(typeof(Autodesk.Revit.DB.View));
viewCollector.WherePasses(viewFilter);

if (vw.CanBePrinted && && !vw.IsTemplate !(vw.ViewType == ViewType.Elevation))
set.Insert(vw);
}
break;
case PDFExportOptions.Elevations:
viewFilter = new ElementClassFilter(typeof(Autodesk.Revit.DB.ViewSection));
viewCollector.WherePasses(viewFilter);
foreach (Autodesk.Revit.DB.ViewSection vw in viewCollector)
{
if (vw.CanBePrinted && !vw.IsTemplate && vw.ViewType == ViewType.Elevation)
{
set.Insert(vw);
}
}
break;
case PDFExportOptions.Schedules:
viewFilter = new ElementClassFilter(typeof(ViewSchedule));
viewCollector.WherePasses(viewFilter);
foreach (ViewSchedule vw in viewCollector)
{
if (vw.CanBePrinted && !vw.IsTemplate)
set.Insert(vw);
}
break;
}
if (_pdfExportSetting != PDFExportOptions.None && set.Size > 0)
{
Transaction tr = new Transaction(doc, "tr_pdf_print");
try
{

doc.Print(set, true);
tr.Commit();
}

finally

除了 IsPrintable 字段之外,您还需要检查的另一件事是视图是否实际上是视图模板。使用 IsTemplate 来检查。
这对我来说太复杂了,可能对 Revit 来说也是如此。
您有一个过滤元素收集器。
在这些元素的迭代中,您尝试启动事务并打印。
首先,将过滤元素迭代、交易和打印分离成三个完全独立的操作。
然后弄清楚这三者需要如何互动。
尽量减少互动,你的问题就应该得到解决。
