There is no XREF equivalent in LibreCAD. You have to make a frame 48 times the size of ARCH D (24"x36"). You may save this as a library file. Into this you draw or copy the architectural drawing, drawn 1 to 1. Or copy/import the frame into the drawing... how ever you see it.
Then at the printing process, in Print Preview mode, you set the scale 1/48. And print staying in that mode. Same applies to export to pdf.
