This is way I'd do it.
Start a new drawing to be the consolidation of the individual ones and define individual layers for them.
Open one of the drawings, select the section (maybe all) of interest and copy it to the clipboard (Ctl C). Switch back to the new drawing, choose Edit|Paste special, then move the newly inserted section to the required layer.
Lock that layer, switch back to layer0 and then repeat for each of the required drawings.
When everything is in your new drawing, unlock each layer in turn and move it's contents to an appropriate place to achieve the required spacing. Format|Align can help with this.
Scaling is best done in paper space - leave model space at actual size.
