Scaling .dwg files in Solidworks Drawings

Hi there,

I have a lot of Inventor .dwgs that I need to open in SW and convert to PDFs.  Some are large or unusual shapes and appear as much larger than the Solidworks drawing sheet when I open them using the SW launcher - and therefore the PDF only captures a corner of the drawing.  Is there any way to efficiently scale these down?  The sizes are not consistent between the drawings at all.

I have a very large volume to work with and have a macro written that will open/save the files - so the ideal solution would be something I could write in to the macro.

Thanks!
