Ok, thanks!
But what happens if there aren't any tabless pieces?
Note: I'm not making a closed model now, I just want to know how
If there is not a suitable tabless piece, then you go into pep designer and make one. Study the model before you even print it out, choose a face that you think would be a good closing piece (preferably a somewhat large rectangular area) and make it tabless using the tab edit function. This works even if you don't have a key to designer, you won't be able to save it, but you can still do it.
This is one of the best looking builds I've seen yet. I especially like that AR, get that thing done, I want to see the finished product!!
Thanks! The AR is still in the state it was on its last update. I will be finishing it, but only after the suit is done. I will be posting it in its finished state in this thread, though.
