Don't know about Smithsonian plans but there are some on the web:

Hope I put that in correctly.   If it does not work simply google "Santisima Trinidad" & "plans"

There's a copy of the outboard profile, at least, in the National Archives.  I've got a print of it somewhere, but I'd have trouble laying hands on it.  The text is in Spanish, and it certainly appears to be contemporary with the ship, though I haven't studied it in much detail.  It was explained to me that somebody in the Navy got hold of it while the ship of the line Pennsylvania was in the design stage.

Had a look at these plans, and am not sure how accurate they are.  Certainly, the plans do not appear to match any of the contemporary Spanish paintings of the ship.  One thing that immediately leaps out is the squared off transom/galleries.  In every painting I have seen of the ship, this should be a very round 'horseshoe' shape, not squared off (for example, as is seen in HMS Victory)..... In fact, the 'horseshoe' stern is almost a trademark recognition feature for Spanish ships of the period...
