You can make the doors and windows as greyscale models as flick said - but I suspect since you ask at all that that may be advanced for you... so the answer that you probably can actual deal with is this: yes, make any graphic or photographic graphic of a door or window and use it as a texture map on cube shaped as a door or a wall, etc. There are a number of places online where you can download window and door textures to try it out with before you make your own - including www.marlinstudios.com, or www.3dlinks.com under free textures. - Dave www.citizendave.com
