Adriatic posted:I like to work from the center to the edges. On large, tight boards, I may fit the large suff first, "just incase". If there is a problem fittlng something, it's usually because of part change, etc. (change in overall size, different case shape or even leg orientation, etc) it is most often easier to change position of a small part (like instead of flat, you can solder one end close to the board and stand it straight up, and use the long leg looped like a candy cane, for going back to the board.)
One thing you clearly should do, especially with a new board design, build ONE and see if everything fits. Don't ask me how I know this.
