        Hello Fredo,

        I have almost the same thing to do : a wing - but this time curved like a kitesurf wing.

        I have yet done this with a triangular half wing and CurviLoft worked fine for this with 3 edges, but since I have added some right tips to do a trapezoidal half wing, I'm not able to re-do the miracle.

        The problem : I would like to make a skin on the upper face following the tailing and the leading edges as rails, with the upper half of a foil as upper skin shape, then end flat to the tip.

        In attachment you will find the half of the wing I talk about :
        The purple is the upper half foil shape, the dark red is the tailing edge, the dark green is the leading edge and the green is the tip.

        This happen after I select Tailing and leading edges as 1 & 2, then clic, then select upper foil shape and tip as 3 & 4, then "skinning" : nothing happens.
        The same trying almost all other selecting orders.

        Could you take a look and tell me were I'm wrong please ?

        Best Regards,
        Guy

          I mocked-up something similar to your picture and can't get it to fail. Seeing as I can make a number of things fail, perhaps you should post your SU file, to see what it is exactly. But the way I am doing it is: I just select all of it and pick the skinning tool.

            Thank you very much for your try to help pbacot,
            here in attachment you will find a SKP file with the half kite wing a talk about to test it.

                you have a tiny line in there at an angle too steep to be picked up by curviloft's autoselection.. (it's in between the red and purple selected lines of your screenshot)

                either a) zoom in real close and select that tiny line manually or b) fix the curve so it's continous..

                (option b being the best.)

                [EDIT] actually, you have more errors going on than just the one i mentioned.. i'm out the door..
                someone else can pinpoint them for you 😉

                  Just amazing and awesome ! Many thanks cotty ! 😄

                  Jeff, I tought this, but very difficult to fix and CurviLoft auto-fix function does not seems to work on my so dirty design. I have to re-draw the stuff but I'm not able to do more fine within SU.

                  Anyway, I have now some material to test and work on.

                  Best Regards to all, and best wishes !

                    I concur with Fredo.

                    What you need to do is take a copy of the chord at the root and scale it to (at least) 1 other rib location near the tip, but just before the tip curve starts.

                    Then CL skin individually the inner top and outer (tip) top airfoil, then do the bottom in 2 goes as well. Only explode the surfaces after all curves are satisfactory.

                    Should take all of 5 minutes.

                    If you have a problem, come back here with your SKP file and I will do a detailed explanation.

                        I've welded some lines and Curviloft asked me if it should repair some issues ...

                          Thank you for checking and fixing the wing.
                          would like to know what you did and where i need to look for the next time.

                            Cotty:

                            Never mind my last question, i found out what i`m did wrong the whole time...
                            I installed curvizard and select all contours 1 by 1 and using the make curve weld option.
                            and your right.. the script was telling me also to fix some problems.
                            After that there was no problem selection those lines(curves) and make the wing.

                            this will keep me going for a while.

                            Thanx all.

                              Cotty & Trion

                              The reason I would split the wing into 2+ parts is to preserve the chord section along the inner span section.

                              Doing it in 1 go (per side) gives a nice looking result, but the chord tends to be flattening towards the outer section and wing tip.

                              That is NOT a fault of Curviloft; it's just the way it works going from a "shape" to a point. Intermediate proportional "shapes" result in a better overall curve.

                              This may not be relevant to a model for "show" but could be critical if accuracy is important. Such a case would be if drawing internal wing structure was part of the model, rather than just an outward appearing skin or mold line.

                                I cant seem to get Curviloft to appear in SketchUp. As far as I can tell, I installed that and LibFredo6 correctly. Any help would be appreciated! Thank you for your time.

                                  But you haven't installed Curviloft correctly. You've not maintained the file structure as described in the first post of this thread.

                                  All of the files in the red box as well as the folder called IMAGES_Standard should be in a folder called CURVILOFT_Dir_12.

                                        Where is the file called bootstrap_Curviloft.rb? It should be in a folder called CURVILOFT_Dir_12 but I'm guessing it isn't.

                                        In fact you should have all these files in that folder.
