      Hello Experts,

      I have been generating 3D coordinates in Excel, and importing these into Sketchup using the points cloud plug-in, which works very well. Is there a plug-in or other means to import connection data? Some of my coordinate sets have >1K points. So, the connection matrix would have >1M cells.

      Thanks to all of you,

      Andrei

          Hi Pilou,

          I very much appreciate your suggestions, but I did not find a solution among them. I have attached an .skp file, illustrating my challenge. I think sdmitch's Connect Guide Points, and then Fredo6's Curviloft, should create a wing from these guide points. But in my hands, Curviloft detects errors in the outputs from Connect Guide Points. Any suggestions?

          Thanks!

          Andrei

            Sorry, must have been a glitch in my file, or a user error by me. Connect Guide Points and then Curviloft will create an airfoil from these guide points.

              Save your file as V6 skp 😉

                My Connect Guide Points will only connect those points that are in each profile group which you have to select one at a time. It is not designed to connect the profiles. Curviloft will need a lot more to workwith than that.

                The biggest problem with this type of situation is that you can never be assured that the points will be found in the correct order. Taking a few things from various plugins, I was able the piece together one that produced the attached model.

                Nothing is worthless, it can always be used as a bad example.

                  What you need to do is make a set of edges that replicate each of the 'ribs' in turn.
                  Once you have those CurviLoft or some of my EEby.. tools which will then 'loft' between them.

                  If your points [e.g. x,y,z] are ordered and in a file [TXT/CSV etc] then it would be relatively straightforward to read them into an array of points, from which you can use the method some_entities.add_edges(array_of_points) to add the edges that go between them; rather than trying to get something else to guess how to 'join-the-dots' after they already loaded as guide-points in the model...

                    Pilou, sdmitch, and TIG,

                    I very much appreciate your help. Now I'm generating thousands of guide points in Excel. I think editing a connection matrix in Excel would be just too much. But for me, using Connect Guide Points to create tens of 2D airfoil sections, and then CurviLoft to create 3D surfaces between them, is working OK. I haven't yet validated Pilou's suggestion to save as V6 skp, but I am pretty confident the intermittent troubles CurviLoft has with outputs from Connect Guide Points is addressable by a file handling SOP.

                    What a capable and helpful community.

                    Andrei

                      sdmitch, did I understand correctly, the SKP file you uploaded was created by a plug-in you just wrote, which accepts a guide points and connection matrix input? If so, that's a great plug-in! Andrei

                        This is just for more people can reload your file for maybe try to find a solution to your problem! 😉
                        Like me, now I can't reload your file! 💚
