      Hi,
      bool tools said that all figurs must be ''solids''
      pls could you tell me what ''solid'' means ?
      all my figurs are components only and I cannot handle the 3 tools of booltools well, they dont give me any results
      it give me that words

      I would like to make this

        Look at Entity Info with a component selected. if it doesn't say "Solid component" you'll run into trouble with BoolTools. You can use ThomThom's Solid Inspector to locate the problems with your components. Typically components aren't solid because there are extraneous line segments or missing faces.

        Please don't take offense at this but it seems to me that you are trying to run before you've learned to walk. It would be a good idea to start with simpler models to actually learn how to use SketchUp before getting into these extremely complex models you're making.

          it's not written ''solid''
          for your other subjection I will look after it tomorrow

          p.s. I finished my work on reversing faces, you can see the result on this component for example
          I did the same on bigger buildings to

          no worry I don't take offense what you told me
          it's true that I am getting into some complex models lol
          that's my biggest problem haha

            Good luck. If you would start with something much simpler, you could work out a lot of your learning much more easily. Starting as you have, you've made things so complex that it is difficult to understand what is wrong when things don't work.

              I see
              I have a small idea for correct this issue, it would be an additional extra that I will add to the back of the ship, a simpliest form which could be more easier a solid, I will post the result if succeeded
              anyway, thanks for your help

                Let's look at it another way... What is a 'Solid' ?

                A 'Solid' is a group or component that contains only geometry - edges and faces [it can also contain 'guides', but they are special because they do not 'interact' with other geometry etc].
                Every edge in this collection must have exactly two faces - no more faces, no fewer faces.
                So any edge without faces will break the 'solidity'.
                It also means that any 'hole' in a face [no matter how tiny] will break the 'solidity' because the edges around that hole will only have one face.
                Similarly any 'flap' face that doesn't join onto other faces will have some one-face edges and so they'll break the 'solidity'.
                Any 'internal partition' face also breaks the rule that 'edges must have exactly two faces', because some of that face's edges will be shared with another two [or more] faces in the object.
                Also 'Solids' must not contain any nested groups or components etc as these will break the 'geometry' only rule...

                  ok I see
                  so I reverified my components and I can imagine why the number 1 have issues
                  after that I created a simple component which is a 'solid' now, a very simple component (no2)
                  also no3 seems to be very simple and perfect to my eyes, I verified it again, ereased some unusless lines but it still not a solid, I dont know why..
                  can I send you this no3 component and could you tell me if you see something bad on it ?

                    Just attach the file here. From here ("outside") it even (could) look solid so there may be some minor defect.

                      Yes, please attach the SKP file for that component.

                      In the screen shot I see back faces on that component. Does that area have thickness? If not, it is probably the cause of the problem.

                      TIG wrote a very good description of what makes a component solid in SketchUp. You might also consider this. Could the thing you've drawn be manufactured out of real materials? Remember, edges and faces have no thickness. If the part of your component that shows blue in the screen shot has no thickness, it couldn't be manufactured out of, say, metal.

                        Comp#3 has several reversed faces.
                        Arrange for all faces to be 'outward looking' i.e. you should never see any blue faces in a solid.
                        A good test for solidity is to select one face that is correctly oriented [out] and use context-menu 'Orient'. All connected faces should become orientated so that they are all 'out'.
                        But if some edges have more than two faces - e.g. internal partitions - then the faces will be oriented inconsistently, because you can't orient three faces that share an edge correctly, one of them will always be 'reversed in the shared edge', i.e. there will be white and blue faces together - it's topologically impossible to resolve that.
                        Check that there are no 'unfaced-edges, no 'holes' and no 'flaps'...
                        To check for 'internal partition' faces cut a section through the form and you will often see them clearly; edit the component and select+delete to remove the rogue face[s].
                        If you reselect it it will eventually report as 'Solid' in Entity Info, when all errors are corrected.
                        Thomthom's SolidInspector tool will highlight where the object fails to be 'solid' and is a useful tool... but you have to take its results and manually correct the issues it has shown you.

                          True, that skipped my eye actually. 👍

                          Especially that he said he'd already done this. Which means that a single face object cannot have been fixed not to show reversed faces.

                            I cannot reverse them, since they are the 'interior' of my component, there is no tickness, so if I understood well I must creat a tickness for having external white face and internal blue one ?

                            p.s. I saw one issue concerning the circles, it seems they are not totaly complet..but I dont know how to modify them..

                            p.s. I succeeded to find an optional solution, I made it handly and filled up the empty spaces with the pen tool ''L'' (after I can build all other details around the component)

                              Do you understand now why that component as you drew it could never be a "solid" component? It's exactly what we were telling you.

                                It is quite possible to make two components or groups that are NOT 'solid'... but when they are exploded, and then saved as a new component or group they could merge and become 'solid'.
                                Because their various faces/edges will merge and then meet the rules about 'solidness' that I set out in my earlier post. 😒

                                  but when I put it on (prog.files/google/sketchup/plugins.
                                  I open sketchup and it give me an advertising like the plugin is not functional or not work/installation failed

                                      ok, just a few minutes

                                      p.s. for conclude the solid component and be sure I understood well
                                      like this my reactor component is in good way to be solid ?
                                      blue faces inside, white outside = no nude faces (blue outside)
                                      only the circles aren't really good (I think that0s the only issue, but certainly thomthoms will tell it..

                                        That's certainly got a chance of being solid.

                                        I don't know why you keep ignoring requests to post the component. This could have all been sorted out days ago. 😒
