Michael,

I'm getting better at using groups effectively.

I am still making foolish mistakes such as trying to copy one object in the group and end up copying the entire group.

But one error that sometimes occurs is a bit more annoying.

When working on one object in the group I often use the boolean tools to make changes to the object and when I do it right they work fine.

What isn't so good is when I manage to select the group by mistake and then the program ends up working hard to apply the boolean operation to all of the objects in the group.

I realize they are my mistakes but what if you could somehow analyze what I just told the program to do and ask if I actually want to do what I just tried to do, such as asking me if I really want to union the 37 objects that are selected.

Not sure exactly what might help but Just a thought.

Thanks.

Frederick
