      Hello Fredo, I'd love to know if you can extract the lines in between when you use loft by spline. I'm using two lines and the tool, I'd love to get the line.

      Those are the lines I want to get in order to create this kind of design.

      Thank you so much!

        In the button palette, you have a section titled "Geometry". The first two buttons gives options to keep only lines in one or the two directions (use the tooltips for details).

          Hi,
          I think what yo want to achieve is something like Loop Selection in 3DSmax. You can use ThomThom's Quad Face Tools, convert your mesh to quads, then select quad loops.

          There is also a small plugin by Blindcop "Extrapolate selected edge"
          https://sketchucation.com/forums/viewtopic.php?f=323&t=61884
          which will let you select continuation of an edge in a mesh. However, it doesn't manage triangulated faces well (or at all?).

            Fredo, could you please DISABLE Loft by spline tool working with PRE-selected set of edges?
            Or at least give some give pop-up warning (this operation will take a loot of time co compute blah blah blah)?
            So MANY times I have to shut down skp session (=loosing 15 min of work 😒 ) because it's freezing forever trying to guess the appropriate order

              Do you have a model example where this happens

                Select all 7 (not one by one), then run loft by spline-
                permanent freeze. Very common thing.

                  This is just a bug, due to the fact that all contours is exactly spaced at the same distance.

                  Thanks for signaling

                  I fixed it in version 1.7d, just published.

                  Fredo

                  PS: Actually, the long waiting time you had is not infinite. After a number of seconds, you get back control. So there was no need to force an exit of Sketchup.

                    NEW RELEASE: Curviloft v1.7d - 31 May 18

                    Curviloft 1.7d is a maintenance release fixing a bug in the automatic ordering of contours for the Spline tool.

                    See Plugin Page of Curviloft for Download (or use the Sketchup PluginStore plugin for auto-installation.

                      Unprecedented responsiveness Fredo,many thanks!
                      I'll test the update later today.
                      Another imperfection (?, - maybe I just can't find right buttons) I encountered with Loft by spline is that
                      the inter-medial segments can't keep exact dimensions of initial profiles (lowest and highest ones in attached example 12X81m*, storey height is 3.5m). Another issue is that segments are slightly OFFXY Plane.

                      Is it possible to develop some special mode that'd keep segments exactly parallel to the input profiles, and if initial profiles are equal it'd keep their dimensions?

                      • P.S. In this particular case of 50+ storey towers PlayitItAgain script helped a lot.

                        This seems to be a problem of geometry which you can simulate manually.

                        Profile not same length.png

                        If you wish to keep the junction straight, then the intermediate profiles do not keep the same dimensions.

                        Also, the intermediate sections are parallel to the initial profiles. Do you have something different?

                          With prussian pedantry I took all horizontal segments, run make faces and...
                          it did it all 🙂 which proves you are right- they are horizontal. What misleads is "~" sign in measurements, must be some SU glitch.

                            No, what is needed is intermediate segments to preserve initial dimentions of the profile.
                            In attached file the red body is OK (all horizontal segments keep right sizing),
                            and the blue one (lofting with 51 intermediate segments) misbehaves.

                              Then, Curviloft is not adapted, and you should use FollowMe Rotate or TIG Grow extensions.

                              With rotated profile, line joining the begin and end profile corner does not meet the corner of the intermediate profiles.

                              In your red shape, you can see that the short segments joining stores are not aligned and do not form a big straight line.

                                Thanks for mentioning those alternatives- I'll check them. I'm so glued to your tools that completely forgot others 😄
                                BTW the straight line on a blue tower shows the horizontal segments don't sit perfectly on it. The gap is ridiculously small in real life scale (~0.3cm in the middle floors, but big enough to spoil the model

                                    I need to consider this case of indetical profiles more seriously, which Curviloft did not really do.

                                    So I'll come with something more robust.

                                      Hi there,

                                      When selecting more than 3 edge curves, and choosing for junction by orthogonal bezier curves, the surfaces do not get the reach the right spline method result.

                                      Here is what the ruby console shows

                                      Error: #<ArgumentError: Cannot create unit vector from zero length vector>

                                          Sorry for my late reply. Here is the attached 2018 skp file . You can see that the selected mode is only applied between the first 3 curves.
                                          Let me know if I can provide more information.
                                          Cheers
