dont know the tutorial Jr.Who is working on, but there will be a time maybe when you dont have the choice. sure booleans allways give crappy geometry. BUT - since I have to work on architecture projects a lot I can tell -> better you have some crappy geometry which doesnt show up at rendertime then to spend hours on building up by hand, what boleans can do in some minutes for you (considering angles and inclinations of two complex forms). in the end it´s all a matter of time is money. so it isn´t too bad being familiar with booleans.


one thing I did forget to mention is sometimes when you have 2 edges from both meshes sharing allmost the same spot in space, i mean lying on top of each other booleans wont work too. just rebuild the mesh (1edge) a little.
