How To Select All Surfaces Outside A Complex Assembly At Once

Please login with a confirmed email address before reporting spam

Dear Mr. Sönnerlind: Thank you for reply the discussion"How To Select All Surfaces Outside A Complex Assembly At Once?", I had tried the way you suggested, but sorry it's not what my expected. So please check my operations OK? I'll appreciate that.

1.My model is a box with a lid.1

2.I want to click a surface on the outside of the box, and then all of the surfaces outside can be selected(not include the inside).2

3.But now I can do is: first I should select boundary, and then I selected the group by continuous tangent, set the deg 100, after that, I click a surface outside, only the domain with the surface I clicked, it's surfaces outside can be selected, not include the lid, so I must click a surface on the lid, so I can have all surfaces outside. It seems can't be contact between domains.3

So my purpose is one click, all surfaces outside can be selected.4

It's my way, so please tell what is my problem, I'll appreciate that.

Thanks a lot and best regards.
