Hi MikeJ . . . It's funny you've brought this up today, I was just trying it again this morning. No, it still doesn't work. I've tried several times, since owning Vue 4, & Vue 4.03, to do a Boolean difference with an imported object, ( even a very simple object ), but it just won't work. I end up with a very distorted final object. Maybe E-on will have a solution or fix ready for the next patch??? I hope. Heheheh. Have a good one . . . Mark. 8^)
