Don't forget the simple tutorial...
Now, PLEASE NOTE that you need to use a special building technique (otherwise known as 'cheat') to place them directly under roof gables as pictured on the set preview picture.
And the reason why I'm mentioning this here (as well as littering the window set with various mentions) is that the accompanying tutorial felt a little bit shy this morning and chose to remain invisible to the masses, and so some downloaders might be thinking those windows automatically place beneath a gable when they need a bit of a helping hand (as we now know: (otherwise known as 'cheat'). The 'cheat' is actually very easy, but if you've never dared use a building cheat before, then this tutorial shows you exactly what you need to do.
The tutorial IS most simple, and I thank Illiana for both mentioning the method AND allowing me to write the tutorial so you can know about it too. And if you like mountain abodes, Swiss homes, log cabins and such, then you're going to adore Illiana's finished home - soon to be uploaded here at TSR. What's so incredible (to me, at least) is that Illiana's home is pretty much all Maxis content - except for the occasional window or two! ;-) Maxis content (how on EARTH do people manage that with such good results???)
However, DO NOTE that you need the Nightlife or later expansion pack for this building cheat; the cheat doesn't exist in the base game, nor in University. If you have any later expansion pack though, then you're in luck! All is not lost if you don't have any expansion packs though, because the windows themselves work in any version of the game and you can do lots of different things with them - you just won't be able to place them
under roof gables.
