Merging erases details on top object Hi I have a problem where I go to merge two objects, one has incredibly small details and as such when I go to merge, the little edges vanish and I'm left with one solid block.

 Pic related is what I want the end result to be, this is before I merge the two.
I'll add here an example:

starting from an array modifier creating similar details



you should apply it: pressing the "apply" button you get something  like this



then if you join with the underlying shape



details are still there
