Hi Mike,

have a look at this:

Boolean ops

That illustrates what you can do.

Using boolean operations is not always the best way to make shapes in 3D e.g. to make a door shaped hole in a wall, it may be more efficient to create a 2D wall and then extrude it into 3D. This keeps the number of polygons down. However there are some shapes that you must use the boolean ops to create and the pictures on the page above show some.

For Boolean ops to work well in AC3D, the normals in AC3D should be pointing outwards (press 'n' to check), and a 3D object should be 'closed' i.e. no holes in it.
