Shake Siding Pattern

[noah]

I know this has been discussed before but I can't find a decent and basic wood shake siding pattern. The one that ships with autocad that we've been using in Revit has a random horizontal bottom edge and really doesn't portray a traditional shake siding.

I need one that is basically just horizontal lines spaced about 5" apart and random vertical lines. See attached.

I would really appreciate it if someone could share one that they've made. It'd be even more great if someone has these in 5", 7" and 12" versions. And super super great if someone could post a .rvt file that already has the shake loaded so I can transfer project settings to my project.

Thanks!
