I use the boolean features a lot. A good lighthouse can be made by taking a cone and stretching it, getting the lower, fatter part to look like what you might like (without thinking about the light part yet). Then, make it positive and make a negative square to cut off the upper portion, with the point. This will give you a slightly tapered cylinder, which you can adjust in any way you want. Then, after you are satisfied with that, go about building the part that holds the light. Before linking the negative square and positive cone, you might want to push a negative square in for a doorway, or indentation for a nice door, then link the mess together and see what you got. I hope this helped some. Walt "Mike"
