Help With Understanding The Diminished Arpeggio And Chord Options

[MrVegas]

hello everybody.
Im currently sitting at my practice area for hours now practicing sweep picking and arpeggios at the same time with the 7th. At the moment im practicing in the key of A and I am moving around all 7 chords in that key and playing all there arpeggios from the 6th string to the 1st and im am paying close attention to each interval. So I guess im practicing three different thing at once, intervals, sweep picking, and arpeggios.
I see that 6 chords that belongs in the key of A, the 3rd 5th and 7th intervals of them all share the same notes of A major, or maybe im wrong?
I learned to play the diminished arpeggio by going to the 7interval of whatever major key im in or the 2nd of whatever minor key im in the just play 3rds all the way through the arpeggio and that will give me a diminished arpeggio. When I did this I see there is a F in a diminished arpeggio and no F in Amajor or am I mistaken and am I missing something?
so far my understanding of arpeggios is you can play any arpeggio that is diatonic to the key your in at anytime and it will work, but is this the case for a diminished arpeggio as well. I know diminished is not used a whole lot but I still would like a clear understanding of it.
also if someone would say "play a Amajor arpeggio is it always implied to play the 7th with it. or would most people say play a Amajor7th arpeggio?
