    When I use Manifold I obtain that ok
    But When I kill or move the group red repair
    I have the original copy with killed internal faces Yes ok ☀ , but always segments on the faces! 😮
    Does it normal? A simple box with 6 faces must be result ? No clean selection?

      This is correct.
      The internal faces are removed by any edges they has forming part of the external envelope are kept.
      If you want rid of then use one of the tools that removes coplanar edges...
      It could seek to remove coplanar edges too ?

        Here's v2.1
        http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

        It now has the option to remove coplanar edges before triangulation, this will minimize the number of faces -useful if for example internal faces have been removed and their old edges are not needed to keep the external 'manifold' skin intact...

          Cool now we have possibility or not to "clean" the model in the same time 😉

            2 volumes
            copy move

            for each selected (2 volumes) Intersect Selected
            Group

            for each "group" apply Manifold
            with same answers : Yes for the first question (of course)
            and No for the others questions

            Curious result is not the same! 😮
            Is that normal?

              @Pilou,

              tested your .skp on mac and got two different results? first time I opened SU from your download file, 2nd time I opened it from inside SU, but that was the only thing I changed, something odd??

                Manifold has to start somewhere in its checking - the first entity it encounters might not always be the same so you get differing results if there's a big mess...

                Manifold was written to do specific job - check that a group is 'manifold' and if not try to fix it - it is so that when you export your model - e.g. to 3D-printer software - it will work. As it says at the start 'give us break' and try and at least offer it a set of geometry you hope might be manifold - it is NOT a boolean tool to merge volumes - it tries to decide which is the face to keep but sometimes removing or healing something changes the form - hence the colored 'report' group.

                Before using 'manifold' try manually to get rid of at least a few known internal faces etc [x-ray mode + hide is good for this] - then the processing is quicker and more consistent...

                😒

                  I well understand 😄
                  The only curious thing is that it not the same result for 2 similar groups inspected 😉

                        Does/should this work with SU 8?

                        I'm not seeing any colours or new models created, even with the downloaded example but the example skp file is v7.

                        I suspect v8 needs a plugin like this too. If there is some other way to find doubles/duplicates/manifolds etc I'd love to know

                        Cheers

                          In v8 there are 'manifold' functions built in...

                              The new solid tools. Outer shell (available in the free version, too), should do (more or less) what manifold plugin would (unless I am completely mistaken as I have never used this plugin yet)

                                  Cheers! I found a tool called solid Inspector which shows some red and orange lines. I'm not 100% sure what the problem is in some cases (although in others it's obvious). I'll see if I can track down where to ask about those tools 😄

                                  Thanks again

                                    You can ask about Solid Inspector here: http://forums.sketchucation.com/viewtopic.php?f=323&t=30504&p=267832#p267832

                                    IT circles red/orange around edges where there is a hole, or the edge connect to internal faces. In a solid all edges should have two connected faces - if there are more or less it means it's not a solid. These are the areas which the inspector highlights. So check if the faces are connected to internal faces, or if it's a hole. Note that the whole could be very small and you'd have to zoom a lot to see it.

                                      Hi!

                                      Thanx for creating this awsome plugin! I have been working on converting 3D objects from some GIS application and it has been so difficult, until now, that is.

                                      I just have one small and kind of silly question but please bear with me:
                                      After running Manifold a copy of the selected group is created. Wich one is the fixed one? Are both fixed? The way i interpret what happens right now is that the one created is just a "showcase" of what changes have been made and that it should be removed.

                                      / KJ

                                        It then processes the group, making a modified copy of it set off to
                                        one side.
                                        If it has errors then a nested group is overlaid that has these
                                        errors highlighted - red for removals, green for healing.
                                        This error-group has a 'text-handle' so you can easily select it to
                                        move it away or erase it later...
                                        There is a closing dialog which either tells there were no major
                                        errors [although it might have removed non-face/edge entities or
                                        oriented faces and done some triangulation] or it reports the number
                                        of errors.
                                        If X-ray mode is off it asks you if you want to change to X-ray Mode
                                        to look inside the group to see what has been affected.
                                        On Yes/No the tool closes, with the new 'manifold' group now selected.
                                        Otherwise OK to end, with the new 'manifold' group now selected.

                                        Does this answer your query?

                                          Thanx for the quick reply!

                                          Sadly the answer is no. This quoted text is the reason I wrote this post in the first place. And no: I am not trying to be a pain in the ass, I just don´t get it. 😕

                                          "It then processes the group, making a modified copy of it set off to
                                          one side."
                                          This sentence kind of implies that the first "original" group has not been modified but that the generated one has.

                                          "This error-group has a 'text-handle' so you can easily select it to
                                          move it away or erase it later..."
                                          This implies both groups have changed, but in different ways.

                                          So I am thinking the logic could be that the program leaves the original group unchanged for comparison, as that seems to be a big deal further down the text, or that the original group is fixed along with the generated group but that the latter one is just a showcase.

                                          / KJ
