Hi,
I’m taking V7 for a spin and seeing if some of my V6 issues will go away with it.
I do a lot of PDF generating. This is a sample command:
using System;
using System.IO;
using System.Linq;
using Rhino;
using Rhino.Commands;
using Rhino.Display;
using Rhino.DocObjects;
using Rhino.Geometry;
namespace Dev.Common
{
[
System.Runtime.InteropServices.Guid("726ced4a-8585-4a66-9a3c-da1964808c58"),
CommandStyle(Style.ScriptRunner)
]
public class PdfCommand : Command
{
public PdfCommand()
{
// Rhino only creates one instance of each command class defined in a
// plug-in, so it is safe to store a refence in a static property.
Instance = this;
}
///<summary>The only instance of this command.</summary>
public static PdfCommand Instance { get; private set; }
public override string EnglishName => "PdfCommand";
protected override Result RunCommand(Rhino.RhinoDoc doc, RunMode mode)
{
try
{
GeneratePDF.DoStuff(doc);
RhinoApp.WriteLine("Done");
return Result.Success;
} catch (NullReferenceException exception)
{
Console.WriteLine(exception);
RhinoApp.WriteLine("Failed");
return Result.Failure;
}
}
}
public static class GeneratePDF
{
public static void DoStuff(RhinoDoc doc)
{
// Using RhinoScript since ViewTable.AddPageView also doesn't work in V7
string createPage = $"_-Layout \"foo\" 297 210 0 _Enter";
RhinoApp.RunScript(createPage, false);
var pageView = doc.Views.GetPageViews().Last();
var detailView = pageView.AddDetailView("bar",
new Point2d(0, 0),
new Point2d(100, 100),
DefinedViewportProjection.Perspective
);
// This is the offending line. Comment this out, and it will work.
// DisplayMode isn't null after this line.
// Doesn't fail before AddPage(..) further down is called.
detailView.Viewport.DisplayMode = DisplayModeDescription.FindByName("Technical");
detailView.Viewport.Rotate(Math.PI, detailView.Viewport.CameraY, new Point3d(1, 1, 1));
detailView.CommitViewportChanges();
detailView.CommitChanges();
var sheetPdf = Rhino.FileIO.FilePdf.Create();
var sheetCapture = new Rhino.Display.ViewCaptureSettings(pageView, 300);
// This will fail:
sheetPdf.AddPage(sheetCapture);
string partPdfPath = Path.Combine(Path.GetTempPath(), $"{Guid.NewGuid()}.pdf");
sheetPdf.Write(partPdfPath);
}
}
}
Running that will fail in the AddPage line marked above.
The NullReferenceException looks like this:
"Object reference not set to an instance of an object"
...
"System.Drawing"

Since I don’t provide a Bitmap at any point I assume this is somewhere in the application code.
System:
Version 7 BETA (7.0.20273.15004, 2020-09-29)
Mac OS X 10.14.6
I didn’t “upgrade” my application code in any way from V6. I just changed target and then it worked. Is there anything else I should do?
Thanks,
Aske
