I've recently installed ACAD LT 2015. in '14, I had a terrific dwg to pdf capability, both in the publish and in the plot routines. 2015 does not seem to include this function, or does it? I would like to be able to export drawings with multiple layouts into a single, multi-page pdf. It was so easy in '14. Plpease let me know how to get this feature in '15. Thanks!

Haven't used LT in yrs but I suspect it should include the DWG To PDF.pc3 option within the plot dialog window.
you could simply determine the path and location of the plotter configuration files (Options > Files tab > expand Printer Support File Path > expand Printer Configuration Search Path) and then copy any missing files from your home setup to your work setup.
