I'm using Blender 2.81a on MacOS.
I am modelling the 'rook' chess piece, and I want to give it the tower shape with cuts in it. When I select the faces and extrude them down, it makes a hollow shape with the edges, vertices and faces still intact. How do I get rid of these extra faces?
I came across the boolean modifier as a solution but is there any other tool/process that I am unaware of.
