      So I’m running into this problem: after selecting the Boolean object, a line appears, (stays even after applying) but it doesn’t show up in Edit Mode. After applying the Boolean modifier, there’s a face orientation issue. The line disappears when I switch to Exact mode, but there’s still a slight face orientation issue even after applying it in Exact mode.
      I’m not watching the tutorial. I’m trying this on my own, so I don’t know if there was any issue like this in the tutorial as well. But because I’m doing it myself, I really don’t want to watch the tutorial — I want to create it on my own by solving all the problems along the way.

        Hard to tell Deb @AgainstTheFlow ,

        Booleans can be very finnicky.

        The issue with the line, I simple, you have found that already, just use the Exact Solver.

        The Normals issue, looks like some ‘holes’. That is something, that can possibly be solved, by slightly moving the Boolean Cutter Obnject. It is not clear how you use that, is that 2 different cutters, or 2 Boolean Objects, offset from each other. Your Screenshots are a bit confusing to me in that regard.

          @spikeyxxx …Solved! Damn, I must have been really stupid — it was a modifier stack issue. I was applying the Boolean before the Bevel, and that’s what was causing the problem.That weird line issue was solved by switching to the Exact solver. Interestingly, the line was disappearing even when I was just aligning one of my Boolean objects. But yeah, some areas weren’t beveling properly — switching to the Exact solver fixed that too.
          Thanks, mate!
          I added a cylinder, then applied an Array modifier along the X axis. After that, I duplicated the array stack along the Z axis — so that became one stack of a Boolean object.Then I used Alt+D to make another instance, so now there are two Boolean objects. I put both of them into a collection and used that collection as the full Boolean object. I know my explanation might be a bit messy, but I said that because you asked if there were two Boolean objects.
          Anyway, thanks a bunch for always helping!

            Great that it’s solved.

            I thought it would indeed be easiest to use 2 Objects and use Collection as Boolean, but that wasn’t shown in your images, that’s why I wasn’t sure.

              I was deleting one, undoing it, and trying different things — so these screenshots are all different and probably don’t have the collection, as I thought the collection or instances might be causing the problem.
