First the D major 7th arpeggio shapes:
|D major 7th arpeggio shapes (click to enlarge).|
Now remember the difference between the major 7th and the dominant 7th is that the latter has a minor 7th. So it is the same shape as the major 7th arpeggios only that you shift the 7th down a half step.
This is what you get:

I won't show anymore shapes here, but they are easy enough to build by yourself.
- Minor 7th arpeggios are like dominant 7th arpeggios only with a minor 3rd. So, find your 3rds and shift them down a half step!
- Minor 7th b5 arpeggios are like minor 7th arpeggios only with a flatted 5th. So, find your 5ths and shift them down a half step!
What to do with these shapes?
Use them in your playing (obvious, uh?).
See where they are located within your scale. For example, where are these arpeggios relativ to your good old pentatonic scale?
Good luck and have fun!
