      Did you unzip those zip files into the plugins folder?

      Under the text area you are posting, there is an attachment tab.

        OK, so i got it to work on Sketchup 8...still can't get it on 7 pro (maybe it's not compatible?!). I unzipped them and did everything i usually do (i did with my home PC with no problems at all). I think i'll just bounce between the two Sketchup versions as i've spent enough time getting it to work. Thanks for the speedy responses, this site really is awesome.

          Sorry, I was in transit to work. Glad Csaba got you sorted. The plugin is compatible with V7 so it should work. Since it isn't, I would suggest you look again at the install. Or, since it works now on V8, rename the V7 Plugins folder to something like Original Plugins so SU won't look at it when it starts. Then copy your V8 plugins folder and paste it into the V7 location. See what happens when you restart SU7.

            Howdy.

            I'm having a bit of trouble and would appreciate suggestions. I'm trying to skin a pair of surfaces and the curviloft tool isn't working.

            I haven't had that problem before - anyone care to suggest why the two wireframes in the attached file won't skin?

            To clarify: This is supposed to be two parallel surfaces, offset by a small gap. The two closed hoops are what I'm trying to skin.

              Try to weld[.rb] the two loops into curves [loops].
              Try scaling it up x10 to avoid tiny edges/facets issues [scale down after skinning].
              You will find one loop had a minuscule edge off perpendicular that's not needed - erase that and re-weld the rest...
              Then it should skin OK...

                Still not working:
                Found and removed a stray edge
                Scaled up by 10x
                Welded curves together
                Same failure state

                Revised file attached. Still baffled.

                    Sorry. Must not have been clear. Wrong way. I'm trying to loft the two surfaces bounded by the loops, not the space between them.

                      I see. The two sets of curves are a red herring. πŸ˜„

                      I wonder if you might be better off with a different tool for what you want to do.

                        What's weird is that I originally skinned something exactly like this. And now I'm trying to reconstruct it. And it's not working... πŸ˜•

                          The contour is made of a single curve with no sharp angle. Curviloft Skinning does not know where to cut the contour in 4 pieces. In such cases, you simply need to draw dummay segments, for instances at the corners.
                          Skin contour - dummay segments.png

                          Then, you select each of the 4 portions (click on it, then click in empty space).

                          And you apply skinning.

                          PS: I also suggest you simplify a bit the contour to have a more regular spacing of the vertices, and thus obtain a more balanced mesh

                            Argh. Still not working.

                            I added dummy segments, and now when I enter the skinning tool it does take four clicks to select everything. The sections break at the dummy segments. So that's progress.

                            But when I "click to validate" the contour just turns purple and nothing happens.

                            Might this be related to the fact that I'm on a Mac?

                              Your dummy segments may not be well placed (note that the contour curve is placed exactly on top of the group which forms the border surface)
                              In any case, you can first select the contours and dummy segments, and then call Curviloft Skinning.
                              Also, if you explode that group, you'll be more confortable
                              It works for me

                                Thanks for the help. Still can't make it work, but I think it's time to give up and call it a day.

                                I'm guessing it's something unique to my machine/configuration or whatever. I've tried about 20 different approaches / placements of dummy segments / etc and it never works. Very odd.

                                Anyway, thanks again.

                                      I just had the time to install the new version of Curviloft (with Quad faces) and
                                      BOY AM I IMPRESSED 😍 😍 😍 😍

                                      It was great before, but with Quads it is absolutely great. No more tiny surface fragments to clean up (so far as I see). And way FASTER to boot.

                                      I'm just getting into a total revamp of my big airplane projects' fairings, and this new version will make that a piece of cake. Compared to the old way (manual meshing and tweaking) that took days to get a fairing right, the older Curviloft reduced that to a few minute to generate the fairing, and a few hours to cleanup the surface fragments that simply added more lines and faces than needed. I was happy then.

                                      The new version should not need more than a few minutes tweaking if needed at all.

                                      Thanks again Fredo. β˜€ β˜€ β˜€

                                        Fredo - We have A problem 😲

                                        The attached model is an extracted edge of a fairing. It should be a single face and all flat.

                                        When I loft it, I get either a black face then just an empty group (thought that was fixed ❓ ) or nothing happens, but an empty group forms anyway. If I manually join verticies it will form a flat face.

                                        There are no edge fragments, or gaps. The faces perpendicular are all properly formed, as well as the opposite edge to this one.

                                        There are also no "errors" (colored lines) appearing, so I cannot find the problem.

                                        I've had a few like this and it was easier to manually face them, but I figured you shold take a look at it.

                                        Won't form a face.

                                          Interestingly, this file skins fine for me, but what you're describing is exactly like the problem I was having above.
