How to make a half cylinder? I am having a tough time building a half cylinder and have not found any tutorial showing me how to do that.
Go into top view (Numpad 7), enter edit mode, press B, and box select half the vertices. Then press X > Vertices. You may need to rotate so that the edges align to the grid properly. Once youhave done that, select the four inner vertices and press F. Alt right-click on the end edges and press F to make faces for them as well.
