I would try searching the forums with something like "combine drawings" or variants. Also look at the "More Like This" box to the right. I would guess that the "combining Multiple Sheet drawings" thread may help.
I seem to recall that it was a simple matter of copy and paste (ctrl-c, ctrl-v). Try ctrl-c on the sheet in the feature manager of the drawing you want to pull from and ctrl-v in the feature manager of the drawing you want to pull into.If that doesn't work, try variants. If nothing works, you might try pulling individual views in a similar fashion.
Jerry is right about copying and pasting, but I use a little bit different method from the one he described. You can RMB on the sheet tab in one drawing and choose Copy, open the second drawing, RMB on a sheet tab and choose Paste. SW will probably add (2) behind the sheet name, but you can RMB on the tab again and Rename. You will need to repeat this process for each sheet; I don't know of a way to do more than one at a time.
