This is because you have two separate objects, the union{} and the plane{}, in
the macro. When you are calling it inside your object{} wrapper, it is looking
for only one, so when it reaches the second, it returns an error.
Try calling it union{Floor(10,10) } instead, or put the plane and union together
in a union{} wrapper inside the macro.
