Snapping to corners

hi guys i am having trouble with the snapping tool. I am trying to import walls individually to trigger material changes and when i try to align them next to each other they are always a little off. I tried turning the snapping to 1 and i still had issues. does anyone know how i could snap to edges or vertices of an object. Thanks in advance

Try out ‘enable vertex snapping’ in the Quick Settings dropdown.

Cheers,
Michael Noland
