Need help to set the TARGET variable zero in C#.

Hey everyone!

As you can see from the title, I've tried changing the TARGET value, but it also changes the view in the model. How can I do this without affecting the view in the model tab?

Any help would be greatly appreciated. Thank you!

private void ResetTarget() { using (Transaction tr = db.TransactionManager.StartTransaction()) { try { ViewTableRecord vtr = ed.GetCurrentView(); vtr.Target = new Point3d(0, 0, 0); ed.SetCurrentView(vtr); tr.Commit(); } catch (Exception ex) { ed.WriteMessage($"\nError in ResetTarget function: {ex.Message}"); } } }

Your question doesn't make sense.

The Target property defines the center point of a view. If you apply a ViewTableRecord to the current view, it is going to modify the view to have the target specified in the ViewTableRecord.

May we Zoom Extents in a new created side database before saving it? Or set an initial view?

I just found a solution when the TARGET is not equal to zero. The TARGET variable affects the plot window coordinates constantly. So, the solution is to create a translation matrix for it and always transform the plot window coordinates using this translation matrix. My code looks like this:

private Matrix3d GetTranslationMatrixFromTarget() { try { ViewTableRecord vtr = ed.GetCurrentView(); Point3d targetPoint = vtr.Target; if (!targetPoint.IsEqualTo(Point3d.Origin)) { Matrix3d translationMatrix = Matrix3d.Displacement(-targetPoint.GetAsVector()); return translationMatrix; } else { return Matrix3d.Identity; } } catch (Exception ex) { ed.WriteMessage($"\nError in GetTranslationMatrixFromTarget function: {ex.Message}"); return Matrix3d.Identity; } }

And used like this:

private void ValidateAndPlot(Layout layOut, Point3d point0, Point3d point1, string path, string fileName, PlotProgressDialog pd) { Matrix3d matrix3D = GetTranslationMatrixFromTarget(); point0 = point0.TransformBy(matrix3D); point1 = point1.TransformBy(matrix3D); Point2d min = new Point2d(point0.X, point0.Y); Point2d max = new Point2d(point1.X, point1.Y); string style = layOut.CurrentStyleSheet; if (style == string.Empty) { style = "acad.ctb"; } string plotDeviceName = "DWG To PDF.pc3"; Extents2d pw = new Extents2d(min, max); try { using (PlotInfo pi = new PlotInfo()) { pi.Layout = layOut.ObjectId; using (PlotSettings ps = new PlotSettings(layOut.ModelType)) { ps.CopyFrom(layOut); PlotSettingsValidator psv = PlotSettingsValidator.Current; psv.SetPlotWindowArea(ps, pw); psv.SetPlotType(ps, Autodesk.AutoCAD.DatabaseServices.PlotType.Window); psv.SetPlotConfigurationName(ps, plotDeviceName, layOut.CanonicalMediaName); if (ps.CurrentStyleSheet == string.Empty) { psv.SetCurrentStyleSheet(ps, style); } psv.SetPlotPaperUnits(ps, layOut.PlotPaperUnits); psv.SetUseStandardScale(ps, true); psv.SetStdScaleType(ps, StdScaleType.ScaleToFit); psv.SetPlotCentered(ps, true); psv.SetPlotRotation(ps, layOut.PlotRotation); pi.OverrideSettings = ps; using (PlotInfoValidator piv = new PlotInfoValidator()) { piv.MediaMatchingPolicy = MatchingPolicy.MatchEnabled; piv.Validate(pi); if (PlotFactory.ProcessPlotState == ProcessPlotState.NotPlotting) { using (PlotEngine pe = PlotFactory.CreatePublishEngine()) { pd.OnBeginPlot(); pe.BeginPlot(pd, null); pe.BeginDocument(pi, null, null, 0, true, Path.Combine($"{path}\\{fileName}.pdf")); pd.set_PlotMsgString(PlotMessageIndex.SheetProgressCaption, $"Plotting: {fileName}"); pd.OnBeginSheet(); PlotPageInfo ppi = new PlotPageInfo(); pe.BeginPage(ppi, pi, true, null); pe.BeginGenerateGraphics(null); pe.EndGenerateGraphics(null); pd.SheetProgressPos = 100; pd.OnEndSheet(); pe.EndPage(null); pe.EndDocument(null); pd.OnEndPlot(); pe.EndPlot(null); } } else { throw new InvalidOperationException("Plot engine is in an invalid state."); } } } } } catch (Exception ex) { throw new Exception($"{ex.Message}"); } }

You can open the ViewportTableRecord having the name "*Active" and modify it.
