Layouts and printing / Plot to multi sheets PDF
« on: March 17, 2013, 11:22:01 AM »
Hi,
Here's a little class to be used to plot layouts to a single multi sheets PDF file.
Using example which creates a new instance of MultiSheetsPdf passing to the constructor the current drawing file name with "pdf" extension and all layouts except "Model":
