Thanks for the hint, the problem is placement, How the parts can be placed relatively exactly the same spot, so that the route can be copy and pasted!
That was my point. You copy and paste the tracks and then snap the parts to the tracks.
1) lay out one of the blocks. Be careful to always snap tracks to pad center points.
2) place all of your ICs where you want them. Don't worry (too much) about the passives yet.
3) copy the tracks and vias from the first layout onto each other IC. Use a convenient reference point like one of the IC's pads to snap the tracks into alignment.
4) now move all of the passives into position by snapping their pads onto the ends of tracks.
Voila, a bunch of identically laid out blocks. A couple extra tips (which you should know generally from working in altium but some people may not):
- adjust the snap settings to what works for you. The auto align thing can be frustrating, so find what annoys you the least. I wish they would copy AutoCAD's snap/tracking system, it's pretty much perfect.
- single layer mode is your friend. Makes it easier to isolate the snaps you want
