here it's ... I hope you understand me.
Blendmand, this is a short explanation about how to use this effect, I beg your pardon but is done in five minutes.
Once you decided when or since where you want animate your section:
1.- select from Objects/light and special obejects/utilities "clip plane"
2.- located this plane where you want to initialize your cut
3.- in "movie", make a new animation
4.- add a "new effect" to your animation
5.- From "scene effect" use "basic animation" for instance in this case
6.- go to the first frame and locate where the clip plane will be at beginning of the animation
7.- Go to the last frame and locate where the clip plane will be at the end of the animation (you can do with vertical movement or with horizontal movement (free movement))
8.- Render
your clip plane will make your building appear in your animation
