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.
