Plotting files with api doesn't include paper space objects OR viewport

I'm trying to implement a plot method and have problems getting correct results. Sometimes I get paperspace objects only, and sometimes I get viewports only. I haven't managed to get both at the same time for some reason... and I don't know what I've done to get different. Seemingly nothing!

Here is my code:

public static void Plot(string filePath, string layoutName, string plotName, string canonicalMediaName, string plotStyleTable) { var fileName = Path.GetFileNameWithoutExtension(filePath); var path = Path.GetDirectoryName(filePath); var outFilePath = Path.Combine(path, fileName + ".pdf"); var doc = Application.DocumentManager.MdiActiveDocument; var db = doc.Database; using (var trans = db.TransactionManager.StartTransaction()) { HostApplicationServices.WorkingDatabase = db; LayoutManager.Current.CurrentLayout = layoutName; var blockTableRecord = (BlockTableRecord)trans.GetObject(db.CurrentSpaceId, OpenMode.ForRead); // Getting the layout object from elided method Autodesk.AutoCAD.DatabaseServices.Layout currentLayout = LayoutHandler.GetLayout(layoutName); var plotInfo = new PlotInfo { Layout = blockTableRecord.LayoutId }; var plotSettings = new Autodesk.AutoCAD.DatabaseServices.PlotSettings(currentLayout.ModelType); plotSettings.CopyFrom(currentLayout); var plotSettingsValidator = PlotSettingsValidator.Current; plotSettingsValidator.RefreshLists(plotSettings); plotSettingsValidator.SetUseStandardScale(plotSettings, true); plotSettingsValidator.SetStdScaleType(plotSettings, StdScaleType.ScaleToFit); plotSettingsValidator.SetPlotConfigurationName(plotSettings, plotName, canonicalMediaName); plotSettingsValidator.SetPlotPaperUnits(plotSettings, PlotPaperUnit.Millimeters); plotSettingsValidator.SetPlotRotation(plotSettings, PlotRotation.Degrees000); plotSettingsValidator.SetPlotType(plotSettings, Autodesk.AutoCAD.DatabaseServices.PlotType.Layout); plotSettingsValidator.SetCustomPrintScale(plotSettings, new CustomScale(1, 1)); plotSettingsValidator.SetCurrentStyleSheet(plotSettings, plotStyleTable); plotSettings.DrawViewportsFirst = true; plotSettings.PrintLineweights = true; plotSettings.ScaleLineweights = true; var plotInfoValidator = new PlotInfoValidator { MediaMatchingPolicy = MatchingPolicy.MatchEnabled }; plotInfoValidator.Validate(plotInfo); if (PlotFactory.ProcessPlotState == ProcessPlotState.NotPlotting) { using (var plotEngine = PlotFactory.CreatePublishEngine()) { // Start plot plotEngine.BeginPlot(null, null); plotEngine.BeginDocument(plotInfo, doc.Name, null, 1, true, outFilePath); plotEngine.BeginPage(new PlotPageInfo(), plotInfo, true, null); plotEngine.BeginGenerateGraphics(null); // Finish plot plotEngine.EndGenerateGraphics(null); plotEngine.EndPage(null); plotEngine.EndDocument(null); plotEngine.EndPlot(null); } } } }

I have tried to change plotSettings.DrawViewportsFirst to false, but nothing changes...

I don't know what I can do or why I sometimes get the viewport content and sometime only the paperspace content!

Anyone recognizes the problem or has any suggestions?

Thanks!

Might have something to do with you're layoutId assignment to PlotInfo.

Try this:

... var lm = LayoutManager.Current; lm.CurrentLayout = layoutName; var layoutId = lm.GetLayoutId(layoutName); plotInfo.Layout = layoutId; ...

Simplified copy of Layout2Pdf -- without the PlotSettings changes:

public static void Layout2Pdf(ObjectId layoutId, string pdfPathname) { Document doc = null; LayoutManager lm = null; try { if (layoutId.IsNull) throw new System.Exception($"Invalid Argument: {nameof(layoutId)} IS NULL"); if (string.IsNullOrWhiteSpace(pdfPathname)) throw new System.Exception($"Invalid Argument: {nameof(pdfPathname)} IS NULL"); var db = layoutId.Database; if (db == null) throw new System.Exception($"Not in DB: {nameof(layoutId)} "); doc = AcadApp.DocumentManager.GetDocument(db); lm = LayoutManager.Current; lm.SetCurrentLayoutId(layoutId); if (File.Exists(pdfPathname)) File.Delete(pdfPathname); var psv = PlotSettingsValidator.Current; using (var plotInfo = new PlotInfo()) { using (var plotEngine = PlotFactory.CreatePublishEngine()) { plotEngine.BeginPlot(null, null); var validator = new PlotInfoValidator() { MediaMatchingPolicy = Autodesk.AutoCAD.PlottingServices.MatchingPolicy.MatchEnabled }; plotInfo.Layout = layoutId; validator.Validate(plotInfo); plotEngine.BeginDocument(plotInfo, doc.Name, null, 1, true, pdfPathname); using (var pageInfo = new PlotPageInfo()) { plotEngine.BeginPage(pageInfo, plotInfo, true, null); } plotEngine.BeginGenerateGraphics(null); plotEngine.EndGenerateGraphics(null); plotEngine.EndPage(null); plotEngine.EndDocument(null); plotEngine.EndPlot(null); } } if (!File.Exists(pdfPathname)) { throw new System.Exception($"Create PDF failed "); } } catch (System.Exception ex) { throw; } }

Thanks, but unfortunately

LayoutManager.Current.CurrentLayout = layoutName;

LayoutManager.Current.SetCurrentLayoutId(layoutId);

did not make any difference...

It's not the Set Layout but the LayoutId assignment to PlotInfo what looks suspicions to me.

My advise:

0. Create the Layout with the required PlotSettings manually.

1. Then create the PDF without the PlotSettings modifications and use the first four assignments.

2. Then when a valid PDF has been made, Add The PlotSettings modifications.
