Pre Scriptum: Sorry for my english language.
N.B. Abstract article.
I think, may the "minus" clause be useful for "union" and "merge" ?
Often need make hole, and then allocate in this hole some object. For
example:
wall_object, window_hole_object, and window_frame_object (with glasses and
curtains :) ).
Normal way, to make it:
union{
// making wall with hole
difference{
wall_object
window_hole_object
}
// making holled wall with window
window_frame_object
}
Using "minus" clause:
union{
wall_object
// making wall with hole
MINUS window_hole_object
// making holled wall with window
window_frame_object
}
Difference between both cases not very match, but (I think), second case is
more readable.
