Hello Naresh Patre 

thanks for the fast response.

I was afraid this could be the case. Opening all the sheets would require an enormous amout of memory, though, and occupy the machine for hours. Is there at least an 'open all sheets' option so I could go subassembly by subassembly? Or could there be a scrpiting option to open them all, though only one at a time, save them as PDF and close? I could then print all PDFs in a second step.
