AutoCAD 2016 Multipage plot crashing at BeginGenerateGraphics()

Anonymous — Mon, 13 Jun 2016 06:35:05 GMT

I have used below function to create Multipage PDF of all layouts of dwg file. But AutoCAD 2016 crashes when for-loop execute for second layout at BeginGenerateGraphics() line. Same code works perfectly in AutoCAD 2013

My machine configuration is Windows 7 SP1 64 bit, AutoCAD 2016 64 bit .NET framework 4.5

Please help.

[CommandMethod("mplot")]
static public void MultiSheetPlot()

Document doc =
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
Editor ed = doc.Editor;
Database db = doc.Database;

db.TransactionManager.StartTransaction();

(BlockTable)tr.GetObject(
db.BlockTableId,

// A PlotEngine does the actual plotting
// (can also create one for Preview)

if (PlotFactory.ProcessPlotState ==
ProcessPlotState.NotPlotting)

PlotEngine pe =
PlotFactory.CreatePublishEngine();

using (pe)

// Create a Progress Dialog to provide info
// and allow thej user to cancel

Not sure it's the root of your problem, but you are calling pe.Dispose() twice. You use an using and you call explicitly dispose.

Hello Maxene,

Thanks for the reply. The same code works perfectly in AutoCAD 2013 64 bit (Windows 7 SP1) but if I use AutoCAD 2016 64 bit (Windows 7 SP1) it crashes. Please see attached image of Fatal Error.

Please help.

Thanks,

Pushpka

May be you are plotting in the background in 2016. Try to put this line at the top to plot in the foreground:

Application.SetSystemVariable("BACKGROUNDPLOT", 0);

Hello Maxence,

I have added this line at top but still same result.. AutoCAD crash.

Application.SetSystemVariable("BACKGROUNDPLOT", 0);

Surprisingly it works perfectly AutoCAD 2013.

Please help.. I am really fed up now...

There is nothing surprising in that. You know, code changes between releases... I'm afraid I cannot help you more, I've run out of ideas and I cannot spend more time on this issue, sorry.

Thanks for the reply.

Please see attached image from the forum http://through-the-interface.typepad.com/through_the_interface/2007/09/driving-a-multi.html

Someone reports the same problem but Kean Walmsley mentioned that he could not observe the issue.

Can you please help on it further.

Thanks in advance

I tried same above code in the Autodesk 2016 (64 bit) Windows 7 SP1 Microsoft Visual Studio 2015 (same install as my machine), it works without crash.

What could be the reason?

Thanks in advance.

Sometimes, programs can behave differently when there is a debugger attached.

I tried with debugger but same code works. Don't know the reason.

Did you find the answer? I have the same problem.

We had the same problem with the BeginGenerateGraphics method and found that the problem is with Service Pack 1 for AutoCAD 2016. When we uninstalled SP1 for AutoCAD 2016 our program worked fine. We were wondering if anyone knows if this is fixed in AutoCAD 2018 or 2019 since we are considering an upgrade soon?

BeginGenerateGraphics() can throw eGraphicsNotGenerated when you're plotting to a file and the target drive/directory does not exist.
