    . . . the shape (the nose of a car) popped into my head - few minutes later this was modeled using SketchUp w/the SketchyFFD script . . . I really, really love that script!!! 😍

    THANKS!!!

    Thats cool.

    I'll have a small update soon. I added a tool to draw an NxN grid with a control point at each grid intersection.

      I haven't been paying attention to this thread, as I haven't needed a freeform, control point manipulator yet.

      However, I find myself needing to model a very complex tapered helical seashell form. This script is absolutely amazing!!! I don't know how I would have a pulled this off any other way, short of using another piece of software.

      THANK YOU!!!! THANK YOU!!!! What an awesome piece of scripting.

      now, if only Sketchy Physics worked on the mac, too..........

      Cheers, Chuck

        i was modeling a harp and had some problem during modeling . does your ruby can help me ? or is there any ruby/solution for this kind of forms ( a tight one)?

          I dont know if FFD can do that or not. Whats wrong with it? It looks pretty good to me.

            i did it usin pull/push + line tool + 3 hours of tight work!!!! . so there must be a shortcut that i dont know or something wrong whit me.

              hmm... I can see 2 ways to do this with FFD rather quickly... but as far as mm acuracy goes... not so confident.

              Draw harp shape with general thickness in elevation. Use a higher-poly arc so that the segments are not as bad. The group it and FFD... x3... I think. Then you should be able to play for a while to get it to look as you want.

                I would name my next child SketchyFFD if we could make the edge curves (borders) static or locked.

                Any possibility this could be worked out?

                Danke,

                    Indeed, that would be great as that would allow making a FFD group of parts of the organic shape . Manipulating that part would hold a seamless transition with the rest of the object.

                      So i'm using SketchyFFD on a surface I created with SoapSkin Bubble.

                      It works, however the FFD nodes are not aligned in the group that the surface is drawn. They are created next to the surface. So when I'm editing the nodes, I can't really tell which one is relative to which part of the surface.

                      Why are my nodes not aligned with my group when they are created?

                      Am I doing something wrong?

                        Try exploding and regrouping the geometry. The FFD script wants the geometry positioned in a certain way inside the group.

                          CP - Thanks! That worked like a charm.

                          I do think it would be easier to control if the nodes were directly ON the surfaces that you are trying to deform. So you knew EXACTLY what part of the surface the node controlled.

                          At least they are in a relative position, now that I've exploded and re-grouped.

                            The math is such that the control points need to be created exactly on a 3d grid. 😞

                              I posted a new version with a few minor changes.

                              Update Mar 21.
                              -Moved all FFD right click menu items to a sub menu.
                              -Fixed a bug that forced you to have a least 2 control point in each direction. You can now have do 2D grids. IE. 1x4x3.
                              -Added an option to create a NxN 2d patch. A grid with a control point at each intersection.

                              Get it here:

                                  I mis-read this at first -- I thought you were saying you made it possible to encase the model in a grid box, rather than floating points (to help visualize the distances between points).

                                  Great work over all! I'd love to see SU incorporate this as a scale tool (lattice) option.

                                      I am having trouble with the new FFD.
                                      I made a so called 'TIN', made a 4,4,4 FFD out of it and wanted to let the surface curve upwards so I selected the points of the short outer edge and moved them up.
                                      The FFD result however is a mesh soup.... 😞
