I'm completely new to Illustrator, and recently I've been getting into isometric drawings, however I'm experiencing a very frustrating problem with aligning objects to the grid. I'm trying to create a simple road made from small cubes, however whenever I'm trying to put them together there's something wrong as pictured below.
I can't align them right because the original block lies on the grid perfectly while it seems like there's no way to align the copy the same way. I've been trying to do something with Smart Guide and Guides & Grid options but nothing really works for me. Is there any way to align the copied objects to the grid?
Here are my Smart Guides settings
