Hello, I am trying to plot multiple drawings - the code is based off through the interface, for plotting multiple layouts in a drawing. I am having trouble finding information regarding the PlotEngine.
The code below is what I have been using, and runs until it gets to pe.BeginGenerateGraphics(null); , The code is running off a command line, I think it has something to do with the current drawing, but as soon as I add Application.DocumentManager.MdiActiveDocument = dwg; the process halts until I go to "Window" in AutoCAD and change back to the initial drawing
Any help would be greatly appreciated.
