New Discovery - Suspended ceiling install is a royal pain

[DigitalDon]

This stuff is a royal pain to install as a cathedral ceiling. I'll provide details and pics when I get it figured out. The main problem is attaching the 4' sections coming off the main beams to the angle molding on the wall while still maintaining the 4' distance from wall molding to main beam.

Can you make yourself a string line grid at the 4' level?
Say, half the size of the ceiling tiles?
That way you have at least 2 reference points on each tile.
