Boolean operations

[tkbd]

dgud,Thanks for reply.
If Wings3D has a boolean function, it is easier to pipe joint and/or hollow out the solid in any shape.

Wings3D could be positioning/modeling powerfully if existing some geometric elements are present in the 3D-Space by using it.
But if there are few hints in the space, User spends many steps for joining for objects.
The boolean feature can be a means to overcome this weakness.

I wait patiently
