First let to say, as Rokas has pointed out, that the RailClone
plug-in is much more suitable for tasks like that. I would highly suggest you to use it for these purposes. You can check a sample of common bond pattern on this related post
Anyway, as the pattern is simple and regular, it's possible to archive that also with Forest Pack
. Just having in mind, that's developed mainly to distribute a huge amount of geometry and there is no specific tool for "joining items on the corner" / "slicing" or so. These areas need be solved by another Forest object(s) as on attached images. Feel free to check attached scene with showing that workflow. Hope that helps.
