Thanks very much for your replies guys.
Will have a go and let you know how I get on.
Much appreciated.

Hi Folks,
I'm trying to model a very simple boardwalk to be built on a wildlife reserve I manage. It's pretty simple, with slats 600x75x25 fixed (25mm spacing) to stringers or rails 75x50x3600. The slats overhang the stingers by 75mm. Producing a model to be used as part of a specification for contractors has been fairly straightforward, until I try to show what happens at a corner, where the boards need to taper to maintain the 25mm spacing.

My questions are:

1. Is there a clever way of working out how many boards, and the angle they should taper, to use in the corner?
2. Is there a quick way of placing the boards on the model, maintaining the 25mm spacing and (approx) 75mm overhang?

I've had a go using a radial array to place boards (got close to correct taper by trial and error), but I wonder if there's a neater way? I'd like to create the array on a curve of varying radius.

I'll try and attach a print of my (very basic) Sketcup model here. If it works, you'll see that I've left the tapered boards as 2D polygons until I figure out how to size and position them.

Any help gratefully accepted.
Cheers,
