Is tis Open GL or NeHe specific?

You can create a pointer in Door that you will assign teh window address. Now the door has access (thus connected?) to the window. Vice-versa if necessary.

Opengl doesn''t see objects, it sees polygons. If you want a door and window and wall, you need to draw and door and window and wall using polygons.

Well, first of all, translate to the point on which the doors/windows are connected to the walls,
then rotate (as that's probably what you want), then translate to the point the origin of the door/window should be and draw the door/window.

Am i clear?

red=door/window origin, green=the point where the door/window is connected to the wall.

1. draw the wall

this is per moving object:

2. translate (move) to the connection point
3. rotate a certain amount (so the door/window is open, not closed)
4. translate the amount (door/window origin - connection point)
5. draw the door/window
