you really have not given enough information for decent help. are you working additive or subtractive? make sure after you add or sub from your piece that you rebuild geo, sometimes it may not show till you do that. notice the color of your brushes, blue are add and orange are sub, so you will need to make the opposite brush to cut the hole. again which this will be is determined by what mode you are workin in.
