Clapboard is an array by nature. So using the array function in MoI, it's not hard. But, if you were going to do this a whole lot in 1 drawing, it can get CPU heavy. For rendering, a bump map is better (but yet a whole other can of worms). Shown is 8" siding with a 7" reveal.

PS-I've hung a square or two of clapboard in my day (in real life, I mean). ;-)
