Hi.

Thanks, Lobo. Apparently, for 2015, the Legacy Boolean Algorithm must be 'turned on' and I can't find a way to tell whether it's on-or-off or how to switch it.

Also, you see what I'm trying to do: make a water-tight file of this 3D Braille Label for 3D Printing.

Can you suggest a better way to do this?

Thanks!
